This document discusses using in-line IR spectroscopy to analyze reactions in continuous flow systems. It describes challenges in analyzing continuous reactions and how ReactIR can provide real-time monitoring without sampling. Case studies are presented where ReactIR was used to optimize a Doebner modification reaction in a few hours, monitor a hazardous reaction involving hydrazine for safety, and troubleshoot a multi-step synthesis. ReactIR allows rapid screening and optimization of reaction conditions as well as safer handling of dangerous chemicals through continuous monitoring.

A Combined Ozone Remedy for a Mixed VOC DNAPL Source ZoneChapman Ross, P.E.
Background/Objectives. In 2003, 1,300 drums and over 3,000 tons of soil were excavated from a drum disposal area in New England. Residual DNAPL created a 2,500 foot long plume that includes chlorobenzenes, toluene, and chlorinated ethenes. The plume discharges to a wetland and has led to vapor intrusion concerns at downgradient properties. Full-scale source zone remediation has been implemented to mitigate potential risks to ecological and human receptors.
Approach/Activities. Following extensive site characterization, bench-scale testing, and a successful field pilot test, the full-scale source zone remedy began in November 2010. The combined remedy approach uses physical, chemical, and biological treatment mechanisms to destroy the residual DNAPL in the vadose and saturated zones. Soil vapor extraction (SVE) and air sparging target the more volatile compounds, while in situ ozone injection (IOI) targets the less volatile compounds such as chlorobenzenes. Aerobic biological activity is also likely enhanced as a result of oxygen injection from IOI and air sparging. Three ozone injection systems deliver a total of 100 lbs of ozone per day to the subsurface; the SVE system extracts soil vapor at a rate of 650 scfm; the air sparge system continuously sparges air at 50 scfm at approximately 30 psi.
Results/Lessons Learned. Performance monitoring includes analysis of VOC concentrations in soil, soil gas, and groundwater. Quarterly low-flow groundwater sampling has shown substantial decreases in groundwater VOC concentrations relative to baseline. In the first six months of operation, 18 of the 20 monitoring wells sampled showed decreases in total VOC concentrations ranging from 14 to 97% with an average decrease of 57%. Furthermore, the mass discharge of total VOCs in groundwater from the source area has decreased from approximately 105 g/day before pilot-test start-up to less than 4 g/day. Concentrations of VOCs in soil gas are monitored in real-time by an automated soil gas monitoring system equipped with a photoionization detector (PID), and on a periodic basis with Waterloo Membrane Samplers™ that provide a speciated analysis of VOCs in soil gas. Of the 47 soil gas monitoring points that were sampled during the first six months of operation, 36 show decreasing trends in soil gas TVOC concentrations. Minimal rebound was observed in soil gas concentrations after treatment was temporarily suspended. Performance monitoring data have informed periodic system optimization to increase the efficiency of the remedy. These results indicate that the combined remedial technologies are effectively reducing source mass and mass discharge, and that the aggressive two year remedial time-frame will likely be met.
Dom Hebrault presented on using real time in situ FTIR analytics to enhance development and control of continuous processes. He discussed three case studies: [1] rapidly optimizing a Doebner modification reaction using inline FTIR to monitor concentrations in real time; [2] safely monitoring a hazardous indazole synthesis using hydrazine in flow; and [3] improving product quality of a Grignard reaction for drug synthesis from 40% to 1% impurity using inline FTIR process control. The case studies demonstrated how inline FTIR can provide major benefits for continuous flow reaction optimization, monitoring hazardous substances, and process quality control.

This document summarizes research on the reaction of single-walled carbon nanotubes (SWNTs) with organic peroxides. The main findings are:
1) SWNTs induce the decomposition of benzoyl peroxide, p-methoxybenzoyl peroxide, phthaloyl peroxide, and trifluoroacetyl peroxide through single electron transfer, accelerating their decomposition rates.
2) Phthaloyl peroxide showed the greatest functionalization of SWNTs of the four peroxides tested.
3) t-Butoxy radicals were found to add to SWNTs, but SWNTs did not inhibit the autoxidation of cumene by alkylper
The document discusses techniques for high resolution site characterization and indoor air sampling for VOCs and SVOCs using passive soil gas surveys and sorbent samplers. It provides an overview of Beacon Environmental Services' experience and accreditations. The document also presents a case study using passive soil gas sampling to identify sources of contamination at a Department of Defense facility, with maps showing the distribution of detected compounds.

The document summarizes a meeting of the East Fork Watershed Cooperative (EFWCoop). Key points:
1. The EFWCoop supports research projects related to watershed modeling, stream ecology monitoring, assessing best management practice effectiveness, and data management.
2. Water quality monitoring data from a drinking water treatment plant intake shows algal blooms are leading to increased disinfection byproduct levels and taste/odor issues.
3. Updates were provided on using high-resolution soil data and discretizing the watershed for modeling water quality trading scenarios in the Upper East Fork watershed using the SWAT model.
This document summarizes a thesis presentation on mini-fluidic solvent extraction of EPA/DHA from fish oil using silver. Key points include:
1) EPA/DHA yields above 75% were achieved in both a mini-fluidic reactor and stirred tank reactor, exceeding capabilities of current extraction methods.
2) Flow patterns in mini-channels with fish oil and silver nitrate differed from previous studies using synthetic systems and required handling stratified flow.
3) A conceptual continuous process design was presented for industrial-scale extraction with an estimated capital cost of $14.5 million for a 10 ton/day facility.
This document provides guidelines for collecting water and wastewater samples for analysis, including ensuring representative samples, clean sampling equipment, and proper sample containers. It discusses filling containers, composite sampling, and recording critical sample information. Special precautions are outlined for trace metals, organic compounds, and other unstable constituents. Safety considerations like personal protective equipment and hazardous sample labeling are also covered. The guidelines aim to obtain samples that accurately represent the water body and can be reliably analyzed without deterioration prior to testing.

Sumitomo Metal Mining Co.,- Hydrometallurgical Processing Plant For Low Grade...Archie Casey
The Project is located within the industrial facility of Rio Tuba Nickel Mining Corporation (RTNMC) in Brgy. Rio Tuba, Bataraza, Palawan.
Since 1977, RTNMC has been mining saprolitic nickel ores selling them to ferro-nickel smelters abroad. In more than 25 years of operation, it also generated mine wastes of about 25 million tonnes. Called low grade limonitic mine wastes, these are stockpiled around the mine area.
CBNC will process these stockpiles using the technology called HPAL or high pressure acid leach.
Enzyme Based Analytical Chemistry - Nitrate and the U.S. EPAAnna-Marie Davidson
This document discusses the use of nitrate reductase enzymes for analytical chemistry applications such as nitrate analysis. It provides background on how enzymes work and their advantages for analysis, including selectivity, sensitivity, specificity, and safety. It then focuses on the production and use of nitrate reductase enzymes, including their validation for nitrate testing according to EPA standards. The document promotes the use of these enzymes as a non-toxic alternative to cadmium-based methods for nitrate analysis in areas like water quality monitoring.
This document outlines 10 hot topics in biomanufacturing: 1) product mix and business models in biopharma, 2) high-titer processes in mammalian cell culture, 3) downstream processing being driven by mass rather than volume, 4) facility fit considerations, 5) cost of goods and price margin pressures, 6) biosimilars and biobetters, 7) offshore manufacturing, 8) technology platforms and implications of high titer, 9) emerging technologies for biomass removal and contaminant clearance, and 10) single-use technologies and integrated processing. The speaker concludes by emphasizing the need for new perspectives and solutions to address challenges in biomanufacturing.
Remediation of Volatile Organics in Groundwater Using In Situ Carbon (ISC) In...Antea Group
Presented at this year's Battelle Conference by Jack Sheldon, this presentation includes information comparing various forms of groundwater remediation tactics using In Situ Carbon (ISC) injections.
1) Green Pacific Biologicals has developed a genetic engineering platform that enables more stable and efficient nuclear gene expression in eukaryotic algae.
2) The platform allows for rapid genetic engineering of algae to increase carbon fixation and oil production through techniques such as increasing carbon flux into oil and implementing efficient oil secretion.
3) Modeling by Green Pacific Biologicals and a professor at Cal Poly suggests their oil secretion approach could lower the cost of algal biofuels production to $50 per barrel, compared to over $400 per barrel for conventional approaches.
Clean production for (ultra) high vacuum applicationThemadagen
1) The document discusses various cleaning strategies and techniques for producing clean components for use in ultra-high vacuum applications.
2) A step-by-step cleaning process is recommended, starting with pre-cleaning to remove films and dirt, followed by particle removal using wet cleaning or ultrasonic techniques, and finally molecular cleaning such as baking or plasma to remove last molecules.
3) Wet cleaning using ultrasonic cleaning with deionized water is described as able to achieve high or ultra-high vacuum if combined with baking. Proper monitoring of cleaning parameters is important to avoid damage.
Ohio Awwa 2008 Ozone Drinking Water TreatmentARSacco
This document summarizes an presentation about ozone drinking water treatment applications and operational improvements. It discusses how ozone provides multiple benefits including oxidation, disinfection, and improved flocculation. It also reviews regulatory requirements, operational considerations like bromate formation control and taste and odor removal. Finally, it discusses advances in ozone system design including more efficient generators and monitoring improvements.
Spartan Environmental Technologies supplies ozone water treatment and advanced oxidation systems. They provide both skid-mounted integrated systems and individual equipment components. They offer a range of support services including laboratory testing, pilot testing, engineering support, and equipment servicing. Their ozone systems are used for applications like drinking water treatment, cooling water treatment, industrial wastewater treatment, and groundwater remediation. They also represent ESCO International in supplying advanced oxidation processes using technologies like UV/ozone, UV/peroxide, and ozone/peroxide systems.
The document summarizes an in situ biotic/abiotic treatability study at Installation Restoration Site 28 to determine if contaminated groundwater can be remediated. Pilot tests were conducted in three areas using different treatment approaches: emulsified vegetable oil and microbes in one area, lactate and microbes in another, and zero-valent iron with carbon in the third. Groundwater was monitored before and after substrate injection to evaluate changes in contaminant levels and indicator parameters. Initial results show decreases in chlorinated ethenes and increases in reaction byproducts, suggesting the conditions support contaminant degradation.
This document discusses bioremediation techniques used to clean up contaminated sites. It provides an overview of Solutions-IES, a company that specializes in bioremediation, and describes how bioremediation works by stimulating microbes already present or adding microbes to degrade contaminants. The document also highlights example projects where bioremediation was used successfully to remediate chlorinated solvents like TCE below regulatory limits. Emerging technologies are discussed for addressing new contaminants of concern.

The document describes research on extracting EPA/DHA from fish oil using a mini-fluidic reactor and comparing it to a batch reactor. Key findings include:
- The mini-fluidic reactor reached equilibrium concentration at 10°C in less than 36 seconds, while the batch reactor took over 15 minutes. Both systems extracted over 75% of omega-3 fatty acids from the fish oil feedstock.
- Flow patterns in the mini-fluidic reactor deviated from the expected slug flow due to the properties of the actual fish oil and silver nitrate solutions used.
- Hydrodynamic studies showed stratified flow occurred rather than slug flow, indicating practical fish oil processing with silver nitrate may require handling stratified flows
The document discusses upgrades to the Marshalltown Wastewater Treatment Plant in Iowa to meet a phosphorus limit of 1.0 mg/L. It proposes modifying the existing sequencing batch reactor (SBR) process to incorporate biological phosphorus removal (BPR) through additional treatment stages. Modeling of the Virginia Initiative Plant (VIP) and Anaerobic-Anoxic-Oxic (A2/O) processes for the mechanical portion of the plant show they can achieve 40-60% phosphorus removal and meet permit limits.

Sinds 2005 is de put van Weber, een oude stortplaats gesitueerd aan de Nedereindse plassen, onderwerp van saneringsprojecten. Regenwater infiltreert in het stortlichaam en stroomt eruit in de vorm van een vervuilde stroom. Deze stroom bevat een complexe samenstelling van verschillende chemicaliën. Het meest relevant zijn calcium, magnesium, Minerale olie, BTEX en naftaleen. Minder relevant voor deze sanering, maar wel noemenswaardig zijn ammonium en sulfaat. Door de hoge hoeveelheid zouten heeft het water een hoge geleidbaarheid, wat een uitdaging biedt voor de saneringsmethode. Door de grootte van het stortlichaam is het debiet vrij stabiel, tussen 2-3 m3 uur-1. Momenteel wordt het vervuilde water gereinigd in een conventionele zuivering, die zijn levenseinde nadert. Om deze reden is er gekozen voor een duurzaam alternatief, wat weinig onderhoud nodig heeft, namelijk een constructed wetland (CW). Om te testen of het water geschikt is voor behandeling via een CW voert HMVT een pilot test uit.
In deze pilot test wordt het inkomende water voor de zuivering naar een cascade stap toe geleid waarbij het water stapsgewijs in aanraking komt met zuurstof. Door middel van zuurstofinfiltratie neemt de pH van het water toe, wat ervoor zorgt dat calcium precipiteert in een bezinkbak als slib. Hierna wordt het water naar de biologische stap van de pilot toe geleid: een container met daarin 3 bakken, gevuld met verschillende lagen grond met daarin planten. Deze planten wortelen diep en geven het microbioom de extra boost die ze nodig hebben om de binnenkomende vervuiling af te breken.
Dit geheel dient ter simulatie van een helofytenfilter, en als tussenstap van tekentafel naar een scale-up situatie. In de 3 bakken kan worden gespeeld met de aerobe en anaerobe afbraak condities en met de materialen. Voor de huidige situatie, is er een afwisseling tussen aerobe en anaerobe condities in bak 1, gevolgd door anaerobe condities in bak 2, tot slot weer aerobe condities in bak, om een gevarieerd pallet te creëren aan afbraak condities. Daarnaast kunnen deze bakken worden gebruikt om te testen of de planten zijn opgewassen tegen de condities van het water.
Tot nu toe is er grotendeels aan het systeem gemeten in de herfst en de winter, en tijdens deze periode werd gezien dat de pH waarden vrij stabiel zijn. De conductiviteit lijkt te dalen door het systeem heen, wat erop duidt dat er adsorptie is van ionen aan de bodem matrix. De cascade stap doet zijn taak succesvol: het inkomende water is rijk in zuurstof. In het systeem zelf is de zuurstof laag, waar het weer omhoog schiet in bak 3. Dit wordt ook teruggezien in de RedOx condities, wat erop duidt dat het systeem naar ontwerp en toebehoren functioneert. Tot slot hebben we getest of het systeem in staat is om minerale olie af te breken. Tot nu toe lijkt dit goed te gaan, waar er nauwelijks minerale wordt gemeten in het effluent.

Door de grootte van het stortlichaam is het debiet vrij stabiel, tussen 2-3 m3 uur-1. Momenteel wordt het vervuilde water gereinigd in een conventionele zuivering, die zijn levenseinde nadert. Om deze reden is er gekozen voor een duurzaam alternatief, wat weinig onderhoud nodig heeft, namelijk een constructed wetland (CW). Om te testen of het water geschikt is voor behandeling via een CW voert HMVT een pilot test uit.
In deze pilot test wordt het inkomende water voor de zuivering naar een cascade stap toe geleid waarbij het water stapsgewijs in aanraking komt met zuurstof. Door middel van zuurstofinfiltratie neemt de pH van het water toe, wat ervoor zorgt dat calcium precipiteert in een bezinkbak als slib. Hierna wordt het water naar de biologische stap van de pilot toe geleid: een container met daarin 3 bakken, gevuld met verschillende lagen grond met daarin planten. Deze planten wortelen diep en geven het microbioom de extra boost die ze nodig hebben om de binnenkomende vervuiling af te breken.
Dit geheel dient ter simulatie van een helofytenfilter, en als tussenstap van tekentafel naar een scale-up situatie. In de 3 bakken kan worden gespeeld met de aerobe en anaerobe afbraak condities en met de materialen. Voor de huidige situatie, is er een afwisseling tussen aerobe en anaerobe condities in bak 1, gevolgd door anaerobe condities in bak 2, tot slot weer aerobe condities in bak, om een gevarieerd pallet te creëren aan afbraak condities. Daarnaast kunnen deze bakken worden gebruikt om te testen of de planten zijn opgewassen tegen de condities van het water.
Tot nu toe is er grotendeels aan het systeem gemeten in de herfst en de winter, en tijdens deze periode werd gezien dat de pH waarden vrij stabiel zijn. De conductiviteit lijkt te dalen door het systeem heen, wat erop duidt dat er adsorptie is van ionen aan de bodem matrix. De cascade stap doet zijn taak succesvol: het inkomende water is rijk in zuurstof. In het systeem zelf is de zuurstof laag, waar het weer omhoog schiet in bak 3. Dit wordt ook teruggezien in de RedOx condities, wat erop duidt dat het systeem naar ontwerp en toebehoren functioneert. Tot slot hebben we getest of het systeem in staat is om minerale olie af te breken. Tot nu toe lijkt dit goed te gaan, waar er nauwelijks minerale wordt gemeten in het effluent.
This document summarizes information from a presentation on cannabis extraction. It discusses defining extracts and what constitutes an extract in terms of cannabis compounds. It also examines optimizing extraction processes by exploring factors like temperature, pressure, time and their effects on yield, cannabinoid concentration and terpene content. The document compares subcritical and supercritical extraction methods and shares lessons learned from experiments. It also briefly discusses other separation techniques like rosin presses and ice water hash.
Lessons learned from injecting liquid activated carbon suspensionAntea Group
Three gas station sites in California were selected for pilot tests of injecting liquid activated carbon suspension to remediate contaminated groundwater. At the first site in San Jose, substantial contaminants desorbed initially but then total petroleum hydrocarbons declined over 60 days and stabilized. The second site in Oakland showed decreases in benzene and other contaminants within 2-3 months, meeting remedial goals. Lessons learned included that direct push injection may not distribute as expected, biostimulation aids carbon treatment, and substantial reductions are possible within months with the right conditions.

Performance Evaluation of Dairy Wastewater Treatment PlantIRJET Journal
1) The document analyzes the performance of a dairy wastewater treatment plant in Jaipur, India.
2) It evaluates various water quality parameters (BOD, COD, TSS, oil/grease) at the plant's inlet and outlet to assess the plant's ability to treat wastewater to regulatory standards.
3) The results show that the plant significantly reduces all parameters measured (BOD reduced from 1477 mg/L to 12 mg/L) and meets regulatory limits for treated water discharge.
TREATMENT OF DISTILLERY EFFLUENT BY USING ADVANCED OXIDATION PROCESSIRJET Journal
This document summarizes a study on treating distillery effluent using an advanced oxidation process called electro-Fenton process. It discusses the characteristics of raw distillery effluent and its negative environmental impacts. The electro-Fenton process uses Fenton's reagent of hydrogen peroxide and ferrous ions along with electrodes to effectively treat distillery effluent. Response surface methodology was applied to optimize the process parameters - Fenton dosage, reaction time, and applied current. The results showed that a Fenton dosage of 0.01 mol/L, reaction time of 30 minutes, and current of 2A achieved over 90% removal efficiency of COD from distillery effluent.
This document provides information about the Econtrol® T-CA process, a sustainable single-bath dyeing process for polyester/cellulose and elastane blends. The process uses Levafix® and Remazol® reactive dyes and Dianix® disperse dyes, along with Sera® auxiliaries. It allows for dyeing with up to 85% less chemicals, 65% less water, and 50% less energy compared to conventional multi-step processes. The Econtrol® T-CA process involves a single padding, Econtrol drying, thermosoling, and wash-off step for simplified and more eco-friendly dyeing of polyester/cellulose blends.
This document discusses Bio-XD 9240, a biocide product for oilfield applications. It is an organosulfur compound that is effective against bacteria and fungi. It works by interfering with reproductive enzymes and breaks down into other biocidal compounds. It remains effective over a wide pH and temperature range. Bio-XD 9240 helps control sulfate-reducing bacteria, acid-producing bacteria, and aerobic bacteria. It has been shown to not degrade friction reducers or oxygen scavengers. Field tests demonstrate its long-term control of hydrogen sulfide and bacteria. Dosage rates for various oilfield applications are listed.

11. Why
Butane?
• Butane gas provides a sustainable carbon source to stimulate
the growth of indigenous microbial communities
• Many forms of bacteria exhibit accelerated growth under
butane stimulation
• Butane-grown bacteria also produce enzymes that rapidly
degrade toxic chemicals
• Butane is the heaviest and most soluble of the alkane gases
(propane, methane) – important for bioavailability
12. Why
Butane?
• As a gas, butane disperses and diffuses rapidly and broadly
in the subsurface – large radius of influence
• Gaseous nature makes butane uniquely suited to remediation
in low-permeability environments
• Contaminated soil in the unsaturated zone and capillary fringe
also treated
• Easily adaptable to biopiles
13. Why
Butane?
• Butane-utilizing bacteria have been shown to fix nitrogen -
able to produce their own nutrients
• Ability to treat contaminants in either aerobic or anaerobic
environments
• Simple infrastructure – easy to switch rapidly from aerobic to
anaerobic conditions at most sites
• Degradation of CVOC daughter products occurs
simultaneously

17. MTBE Degradation Pathway Using
Butane Remediation
• MTBE = (CH3)3COCH3 / C5H12O
• Enzymes accelerate C5H12O
Demethylation
• MTBE degraded to form tert-butyl
alcohol (TBA) and formaldehyde
• These species quickly decompose
into H2O and CO2
18. Butane Safety
• Non-Toxic – Used in food processing
• Safe, UL engineered panel
• Concentrations generated in the
subsurface with the butane injector are
less than 0.01% of the LEL for butane
in air
• Excess butane in soil/groundwater
decomposes into CO2, H2O, and other
inert species in 2-3 days
