Centrifugal collectors (2)
This document discusses centrifugal collectors and provides details about cyclones. It lists the group members working on centrifugal collectors and then explains the principle and construction/operation of cyclones. Cyclones use centrifugal force to remove particles from a gas stream by forcing the stream into a vortex. They have advantages like low capital cost and can operate under various conditions, but disadvantages include only working for small particles and high pressure drops. The document also mentions mechanical centrifugal collectors but provides no further information.

The document provides an overview of key environmental legislations and acts passed in India from pre-independence to present. It discusses how early laws during British rule focused on resource exploitation rather than conservation. Major legislations started being passed after the 1972 Stockholm Conference, including the Water and Air Pollution Acts of 1974 and 1981. The Bhopal gas tragedy spurred passage of the Environment Protection Act of 1986. Later policies have emphasized a mix of regulatory and economic instruments to control pollution.
Gravity settling chambers for controlling air pollution
1) Gravity settling chambers are used to remove suspended particles from gas by reducing gas velocity to allow particles to settle out under gravity.
2) The simplest chamber is a horizontal duct where large particles settle on the floor, while more advanced chambers use baffles to change gas flow direction.
3) Settling chambers are effective at removing large, abrasive particles before downstream collection and referred to by several names.
Sampling techniques
This document provides guidelines for environmental sampling techniques. It discusses sequencing sampling locations from least to most contaminated and collecting volatile organic compounds first. The minimum sample size depends on analyte concentrations and heterogeneity. Larger volumes are needed for air, water, sediment and toxicity testing. Samples must be properly preserved to minimize changes, with maximum holding times varying by analyte and agency. Appropriate containers and sampling equipment must be selected based on the matrix and parameters of interest.

This study analyzed 9 liquid foundation samples from Malaysia, Indonesia, and Taiwan to determine heavy metal content. The samples were acid digested and analyzed using ICP-MS. All 9 samples contained aluminum and zinc in varying concentrations. The highest aluminum reading was 25.32 mg/l from a sample from Indonesia. Heavy metals in beauty products used daily can accumulate in the body and negatively impact health.
6. proposal report presentation
This document provides guidance for students presenting a proposal presentation. It discusses dividing up the presentation between partners, with each speaking roughly the same amount of time. It suggests rehearsing as a team, being prepared to revise parts of the presentation, and making the transitions between topics and speakers clear. The document also provides questions for students to consider about the organization, slide design, and delivery of their presentation, such as whether the talk fits together coherently and whether the slides have a good balance of text and figures. The goal is to persuade evaluators to support the proposed research project within the 7 minute time limit.
5. discussion review method
This document discusses research methodology and environmental sampling techniques. It covers topics such as operationalization, validity, sampling, sample handling, preservation and storage, selection of sample containers and sampling equipment. Specifically, it provides guidelines on determining sampling objectives, selecting relevant chemical and biological indicators, choosing appropriate sampling locations, equipment and containers, accurately recording and preserving samples, and reporting results. The document aims to help ensure samples are representative and that physical, chemical and biological changes are minimized prior to analysis.
4.1 what's in a literature review
The document discusses literature reviews and the research process. It describes the hourglass model for structuring a literature review with broad context literature at the top narrowing to primary sources relevant to the research problem and knowledge gaps. This focuses the research question which is then widened in the discussion of results. Literature reviews should have breadth, shape, logical flow, appropriate detail, and incorporate primary sources. The key stages of research are planning, acting, observing, and reflecting on one's own practice in an iterative process. Using multiple research methods can strengthen validity and reliability.

Wet collectors
This document discusses different types of wet collectors used to remove particles from gas streams. It describes impingement scrubbers, which use horizontal plates with small holes to accelerate gas and atomize water droplets to impact particles. Spray towers are also discussed, which use spray nozzles to generate water droplets to impact particles as the gas moves upwards. The advantages and disadvantages of each type are provided, such as impingement scrubbers handling flammable dusts but creating waste disposal problems, while spray towers have lower pressure drops but mass transfer efficiencies.
Particulate control
The document discusses particulate control group 2 and their gravity and momentum collector. The collector uses settling chambers and louvers to admit air while keeping out rain and noise. Louvers have adjustable or fixed slats that change the direction of gas streams. Larger particles do not change direction and settle in the dead air space, making it a precleaner for more efficient collectors.
Chap 4
This document summarizes different types of electrostatic precipitators (ESPs), including tubular, plate, wet, and dry ESPs. Tubular ESPs consist of parallel tubes with electrodes running through them, and are designed to eliminate gaps in particle collection. Plate ESPs use parallel metal plates and wires to collect dry particles in multiple parallel lanes, making them suitable for high gas volumes. Wet ESPs use water sprays to collect sticky or wet particles via scrubbing. Dry ESPs periodically rap collected particles off plates into a hopper for removal from the gas stream.
Air noise gases

It then provides a brief explanation of the function of an adsorption tower, stating that it separates components of a rising gas using a falling liquid to trap the gas, and is used for purification and processing in various settings. It notes adsorption towers are designed for specific applications to ensure efficient operation.
Air n noise
This document discusses cyclone spray chambers and orifice scrubbers for removing particles from gas streams. Cyclone spray chambers use centrifugal force to permit good separation of droplets and can remove up to 95% of particles over 5 microns. Orifice scrubbers have the gas flow at high velocity through a narrow section into pools of scrubbing liquid before passing through a series of baffles to remove droplets and pollutants through impingement. The document was written by three students for their lecturer on the topic of these gas cleaning devices.
Cyclone
Packed towers are filled with small objects like catalyst particles or absorbents to perform separation processes like absorption, stripping, and distillation.

Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.

The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.
