Evaluation of an emerging water treatment technology: ceramic membranes

Historically, low-pressure membranes (microfiltration (MF) and ultrafiltration (UF)) used in potable water treatment are made of polymers (polysulfone (PS), polypropylene (PP), polyethersulfone (PES), polyvinylidene fluoride (PVDF) etc). Recently, membranes made of ceramic materials (aluminium oxide) have been developed by MetaWater (Japan), Kubota (Japan) and others and is being marketed in the ...

Use of a ceramic membrane bioreactor (CMBR) to treat wastewater at Guilin University of Technology

A ceramic membrane bio-reactor (CMBR) process was first used to treat wastewater collected from a campus of Guilin University of Technology (GUT). A CMBR with a submerged flat-sheet ceramic membrane module was designed for a Qmax of 300 m3/d. With a stable flux at about 33 L/m2 h, the transmembrane pressure was maintained at −10 kPa until the end of the experiment. The results ...

New treatment plant to feature ceramic membranes

The Parker Water and Sanitation District (PWSD) in Colorado has contracted for a membrane treatment system for its Rueter-Hess water treatment plant project. The new plant will treat water from the Rueter-Hess Reservoir (RHR), which is being built three miles southwest of downtown Parker on Newlin Gulch, which is a tributary drainage of Cherry Creek. The reservoir and associated treatment plan ...

Methods of Purification by Water Innovations, Inc.

Carbon Filtration is used for several reasons. Its primary purpose is the reduction of chlorine to less than 0.1 ppm. Chorine can damage softener resins, reverse osmosis membranes, and mixed bed deionization resins. Activated carbon will also help control tastes and odors, provide organic and hazardous organic chemical reduction, and some particulate reduction. ...

Comparison of optional process configurations and operating conditions for ceramic membrane MF coupled with coagulation/flocculation pre-treatment for the removal of NOM in drinking water production

The increase of Natural Organic Matter (NOM) in natural water sources, partly caused by progressing climate change issues, is a growing concern for drinking water production. In recent years, membrane technology like Reverse Osmosis (RO) or Nanofiltration (NF) has been successfully applied as a robust solution for NOM removal to produce potable water. However, coagulation/flocculation ...

Picking Their Membranes - Part I -

Membrane use by water suppliers may not be new, but suppliers are considering membranes in new ways -- by number and variety of applications. Membranes can work on a wider range of resource waters, more efficiently and for less cost than before. Among membranes' attractions as substitutes for conventional water-treatment technologies, such as filtration, distillation and ion-exchange are: ...

Energetics for gas separation in microporous membranes

Gas separation by inorganic membranes has proven to be effective at laboratory scales, but is now facing challenges in developing for industrial scales. A particular type of inorganic membrane is the class of porous molecular sieves formed by sol-gel method deposited on ceramic substrates. These molecular sieve silica (MSS) membranes are ideally suited to high temperature He, H2, CO2 and CH4 ...

Common Treatment Technologies for Nonhalogenated VOCs

Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with nonhalogenated VOC-contaminated soil. Because a presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site, the presumptive remedy approach will accelerate site-specific ...
