Microfiltration

Arsenic removal from drinking water is a major problem in many parts of the world. We have investigated arsenic removal by flocculation and microfiltration. Ferric chloride and ferric sulphate have been used as flocculants. The use of small amounts of cationic polymeric flocculants, as flocculation

The role of the cake particle solidosity in the context of the shear-induced diffusion model for membrane dominated microfiltration is presented. First the concept of shear-induced diffusion is reviewed to illustrate the importance of the particle solidosity in the formation of the cake. The diffusi

Membrane coalescence is a chemical-free technique for breaking stable oil-in-water emulsions. In this work the effect of oil droplet residence time within the membrane porous matrix was investigated and a novel process is proposed based on intermittent permeate flow (flow or no flow) at 0.01 Hz. Pol

In this work ten different polymeric microfiltration membranes of different materials polyethersulfone (PES), cellulose mixed esters (CE), cellulose acetate (CA), polypropylene (PP) and nylon (NY) with different pore diameters and of different commercial companies have been tested for wine clarifica

Membrane filtration has become firmly established as a primary technology in ensuring the purity, safety and efficacy of modern Biopharmaceuticals. As the Biopharm/Biotech industry comes to maturity filtration has a key role to play in the reliable and economic production of a wide range of biologic

Water shortage problems are becoming more widespread and are encouraging users to treat difficult waters and to value the reuse of wastewater. Membrane processes such as reverse osmosis (RO) have been used to treat such waters as well as sea water (SWRO). The applications, particularly for wastewate

Numerous pilot plant studies and commercial facilities operating all over the world have demonstrated the technical and economic feasibility of reclaiming municipal wastewater treatment plants (WWTP) effluent through dual-membrane treatment processes. Dual-membrane processes such as continuous micro

The water resources of Kuwait are limited to desalinated water to meet the requirements for all freshwater needs, unreplenishable brackish water as a supplementary source for blending and agriculture, and municipal wastewater which is treated and mainly discarded to the sea. Limited quantities of th
