Cross Flow or Tangential Flow Membrane Filtration (TFF) to Enable High Solids...
Cross Flow or Tangential Flow Filtration (TFF) Membrane Plants are used in Desalination, Brackish Groundwater Treatment, High Chloride Surface Water Treatment, Waste Water Treatment Plant Effluent Reuse, Biopharmaceutical, Food & Protein Applications for removal of undesired constituents and harvesting of desireable products. Cross flow membrane filtration technology has been used widely in industry globally. Filtration membranes can be polymeric or ceramic, depending upon the application. The principles of cross-flow filtration are used in reverse osmosis, nanofiltration, ultrafiltration and microfiltration. When purifying water, it can be very cost effective in comparison to the traditional evaporation methods. Techniques to improve performance of cross flow filtration include:
Backwashing: In backwashing, the transmembrane pressure is periodically inverted by the use of a secondary pump, so that permeate flows back into the feed, lifting the fouling layer.
Clean-in-place: Clean-in-place systems are typically used to remove fouling from membranes after extensive use. The CIP process may use detergents, reactive agents such as sodium hypochlorite and acids and alkalis such as citric acid and sodium hydroxide.
Concentration: The volume of the fluid is reduced by allowing permeate flow to occur. Solvent, solutes, and particles smaller than the membrane pore size pass through the membrane, while particles larger than the pore size are retained, and thereby concentrated. In bioprocessing applications, concentration may be followed by diafiltration.
Diafiltration: In order to effectively remove permeate components from the slurry, fresh solvent may be added to the feed to replace the permeate volume, at the same rate as the permeate flow rate, such that the volume in the system remains constant. This is analogous to the washing of filter cake to remove soluble components. Dilution and re-concentration is sometimes also referred to as "diafiltration."
Presentation1 tff
Tangential flow filtration (TFF) is a type of filtration where the fluid flows parallel to the filter surface rather than perpendicular. This allows particles to be swept along the membrane surface rather than building up. TFF has advantages over normal flow filtration like being faster, more efficient, and able to concentrate and exchange buffers in one system. Key steps in TFF include flushing, sanitizing, integrity testing, buffer conditioning, processing like concentration and diafiltration, product recovery, cleaning, and storage. Process parameters like transmembrane pressure, flux, and fouling must be optimized for each application.

Ultrafiltration
Ultrafiltration is the process of removing water from the bloodstream during hemodialysis to achieve solute clearance and adequate fluid removal. There are two main methods of controlling ultrafiltration: pressure control, where blood compartment pressure is increased to remove fluid, and volumetric control, which directly measures ultrafiltrate volume for more accurate control. High efficiency dialysis aims for high urea and solute clearance rates using large surface area membranes and optimized blood and dialysate flows. High flux dialysis uses more permeable membranes to improve clearance of middle and large molecules. Hemofiltration provides solute clearance solely through convection while hemodiafiltration combines dialysis with large volume ultrafiltration for combined con

Membrane Separation Processes
This document summarizes membrane separation processes. It describes that membrane separation uses a semi-permeable barrier to allow faster movement of some components over others. The retained part is called retentate and the passing part permeate. Membrane separation is desirable as it saves energy, has a long membrane life, is defect-free, compact and easily operated. The document discusses membrane materials, permeance factors, transport mechanisms including porous and non-porous membranes. It provides examples of industrial applications like dialysis, reverse osmosis, and pervaporation.
Hybrid system
Distillation is the most important separation technology in the chemical process industry. More than 90% of separations are based on distillation.
Hybrid systems offer an interesting alternative in some difficult separations for distillation with either large number of theoretical trays; large heat loads or both.
Hybrid processes in separation operations are characterized by the combination of two unit operations.
Each unit operation itself is considered to be a separation process, but the combination generates special advantages.
dialysis, ultrafiltration and lyophilization
This document discusses three separation techniques: dialysis, ultrafiltration, and lyophilization. Dialysis uses a semi-permeable membrane to separate molecules based on molecular weight, allowing small molecules to pass through while retaining larger ones. Ultrafiltration concentrates solutions using membranes that retain proteins while allowing water and small molecules to pass through under pressure. Lyophilization, or freeze drying, removes water from a frozen sample by sublimation under vacuum, leaving a dry powder.
Membrane technology
Membrane technology uses semi-permeable membranes to selectively separate substances through diffusion or filtration. It is widely used for water purification and in various industrial separation processes. There are two main types of membrane modules - tubular membranes located inside tubes, and plate and frame membranes consisting of membrane envelopes wrapped around a central drain. Membrane processes are classified based on the driving force used, such as pressure, concentration gradient, electric potential, or temperature difference. Common applications include microfiltration, ultrafiltration, nanofiltration, reverse osmosis, gas separation, and pervaporation.
Membrane separation technology
This document discusses membrane separation technology. It begins by defining membranes and the four types of separations they can perform. It then classifies membrane processes based on permeable species size into microfiltration, ultrafiltration, nanofiltration and reverse osmosis. Each process is described in terms of pore/molecular weight cutoff size and applications such as cell harvesting, virus removal, water purification. Finally, common membrane module configurations including flat plate, hollow fiber and spiral wound are outlined along with their uses in food/pharma processing, water treatment, and other industries.

Membrane processing technologies jan.2012
Membrane technology has been used since the 18th century but only recently has it gained widespread industrial use. There are various types of membrane processes that separate materials using size exclusion, charge, or other properties. The most common membrane processes are reverse osmosis, ultrafiltration, microfiltration, and electrodialysis which see wide use in water treatment, food/dairy processing, and other industries.
Ultra filtration and reverse osmosis
The document discusses ultrafiltration and reverse osmosis membrane filtration processes. Ultrafiltration uses semi-permeable membranes to separate solids and liquids based on particle size. It is used to purify water by removing bacteria, viruses and other pathogens. Reverse osmosis uses pressure to force water through a semi-permeable membrane, allowing pure water to pass while retaining dissolved ions and solutes. It has various industrial and domestic uses, including water purification, wastewater treatment and desalination. Both processes are effective at removing microorganisms and suspended particles from water and liquids.
Filtration
Filtration is commonly the mechanical or physical operation which is used for the separation of products like solids from fluids by interposing a medium through which only the fluid can pass.
Membrane filtration
Membrane filtration uses filters with pores smaller than 0.2 micrometers to remove particles like giardia and cryptosporidium from drinking water. It is effective for tertiary water treatment and reuse or discharge into rivers. However, it does not remove dissolved substances. There are several types of membrane filtration that separate particles of different sizes using pores and pressure.
Solar water disinfection (SODIS) uses sunlight to make contaminated water safe to drink. It involves placing water in clear PET plastic bottles and exposing them to full sunlight for 6 hours, utilizing UV radiation and increased temperature to inactivate pathogens. SODIS is recommended by the WHO and widely used in developing countries as a free and effective household water
Purification of water by membrane Technology
The document discusses various membrane technologies used to purify water, including microfiltration, ultrafiltration, nanofiltration, and reverse osmosis. Membrane technology uses semipermeable membranes to separate particles and molecules of different sizes from water. Microfiltration removes particles between 0.9-90 microns. Ultrafiltration uses membranes with pores between 10-1000 Angstroms to remove molecules like sucrose and polymers. Nanofiltration, which has pores around 0.5-1.5 nm, removes ions and prepares water for reverse osmosis. Reverse osmosis uses membranes that reject 96-99% of salts to produce ultrapure water for various industrial applications.
ULTRA FILTRATION & NANO FILTRATION WITH APPLICATIONS
Ultra filtration and nano filtration are membrane filtration processes. Ultra filtration uses membranes with pore sizes from 0.1 to 0.001 microns to remove particles and molecules. It is used in water treatment, food processing, and industrial applications. Nano filtration uses even smaller pores from 1-10 nanometers to soften water and remove organic matter. It has various industrial and water treatment uses such as removing contaminants and concentrating products while allowing monovalent ions to pass through.

Top 5 water treatment processes
The top 5 types of water treatment processes are: Activated Carbon Filters, Ion Exchange, Multimedia Filtration, Reverse Osmosis, and Ultraviolet.
Membrane process for water treatment
Microfiltration is an inexpensive water treatment process that uses membranes to reduce turbidity, suspended substances, and bacteria. It has advantages like reducing treatment chemicals and microorganisms while lowering costs compared to conventional treatment. However, it may require pretreatment to prevent fouling and scaling, and membranes require replacement every 3-5 years. Microfiltration is used for water pre-treatment in various biological and membrane processes. Ultrafiltration and nanofiltration can remove even smaller particles and molecules but not salts or sugars. Reverse osmosis uses pressure to force purified water through a semi-permeable membrane, leaving behind dissolved ions and larger particles.

The presentation discusses water treatment using nanofiltration membranes. Nanofiltration is a membrane process that uses nano-sized porous membranes to remove multivalent ions, natural organic matter, and other contaminants from water. It provides high rejection of ions like calcium while allowing monovalent ions like chloride to pass through. The presentation covers the nanofiltration process, types of membranes used, its applications in food processing, water treatment, and a case study demonstrating its effectiveness in removing bacteria, viruses, and heavy metals from wastewater. The integration of nanofiltration membranes provides a sustainable solution for water treatment and ensuring access to clean water.
Reverse osmosis system
This document discusses reverse osmosis as an ideal system for water softening. It begins by explaining the history of membrane technology, moving from simple sieves and filters to modern membranes that can separate substances based on differences in solution and diffusion rates. It then defines different types of membrane-based filtration processes based on particle size range, including microfiltration, ultrafiltration, nanofiltration, and reverse osmosis. The key difference between reverse osmosis and other filtration processes is that reverse osmosis uses a semipermeable membrane and osmotic pressure to separate dissolved solids from water. The document outlines the principles of osmosis and how reverse osmosis works by applying pressure greater than natural os

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.

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.

Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. 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.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.

Increasing urbanization, rural–urban migration, rising standards of living, and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities in Nairobi City. It has been noted in other contexts too that increasing population, changing consumption patterns, economic development, changing income, urbanization and industrialization all contribute to the increased generation of waste.
With the increasing urban population in Kenya, which is estimated to be growing at a rate higher than that of the country’s general population, waste generation and management is already a major challenge. The industrialization and urbanization process in the country, dominated by one major city – Nairobi, which has around four times the population of the next largest urban centre (Mombasa) – has witnessed an exponential increase in the generation of solid waste. It is projected that by 2030, about 50 per cent of the Kenyan population will be urban.
Aim:
A healthy, safe, secure and sustainable solid waste management system fit for a world – class city.
Improve and protect the public health of Nairobi residents and visitors.
Ecological health, diversity and productivity and maximize resource recovery through the participatory approach.
Goals:
Build awareness and capacity for source separation as essential components of sustainable waste management.
Build new environmentally sound infrastructure and systems for safe disposal of residual waste and replacing current dumpsites which should be commissioned.
Current solid waste management situation:
The status.
Solid waste generation rate is at 2240 tones / day
collection efficiently is at about 50%.
Actors i.e. city authorities, CBO’s , private firms and self-disposal
Current SWM Situation in Nairobi City:
Solid waste generation – collection – dumping
Good Practices:
• Separation – recycling – marketing.
• Open dumpsite dandora dump site through public education on source separation of waste, of which the situation can be reversed.
• Nairobi is one of the C40 cities in this respect , various actors in the solid waste management space have adopted a variety of technologies to reduce short lived climate pollutants including source separation , recycling , marketing of the recycled products.
• Through the network, it should expect to benefit from expertise of the different actors in the network in terms of applicable technologies and practices in reducing the short-lived climate pollutants.
Good practices:
Despite the dismal collection of solid waste in Nairobi city, there are practices and activities of informal actors (CBOs, CBO-SACCOs and yard shop operators) and other formal industrial actors on solid waste collection, recycling and waste reduction.
Practices and activities of these actor groups are viewed as innovations with the potential to change the way solid waste is handled.
CHALLENGES:
• Resource Allocation.

An Introduction to Types of Water Membrane Filtration
- 1. An Introduction to Types of Water Membrane Filtration Agape Water Solutions
- 2. Introduction • Drawing on decades of experience, Agape Water Solutions provides custom-designed industrial water solutions for long-term service across a diverse range of industries. Products offered by Agape Water Solutions include water membrane filtration systems. Purifying water through membrane filtration technology involves putting in place a barrier layer that allows only certain types and sizes of molecules to pass through. The membrane removes bacteria, viruses, solids, and other undesirable materials that have not been dissolved into the water. Benefits of employing a membrane filtration system include reduced energy consumption and lower operating costs.
- 3. Water Membrane Filtration • Current types of membrane filtration technology include microfiltration, nanofiltration, ultrafiltration, and reverse osmosis. Microfiltration relies on membranes with openings in the range of 0.03 to 10 microns and a pressure force of 15 to 60 pounds per square inch (psi). Membranes used for nanofiltration have openings of only about 0.001 microns and require force pressure up to 150 psi. In ultrafiltration, membranes have openings of about 0.002 to 0.1 microns and an operating force of about 30 to 100 psi. Reverse osmosis has membranes with even smaller openings and thus employs ionic diffusion to separate water from foreign molecules. Contact www.agapewater.com for information about membrane systems for water purification.
