Submerged membrane

Performance and fouling characteristics of two pilot-scale polyvinylidene fluoride hollow fiber microfiltration membranes for drinking water treatment were studied under the same flux and physical cleaning conditions. It is expected that this paper can provide insights into the functions of operatio

Although submerged microfiltration is widely used as a pretreatment process for surface water treatment and RO desalination, its high energy consumption is a major drawback compared to conventional pretreatment. Especially, aeration during filtration is an energy-intensive step in most submerged mem

The performance of the submerged membrane filtration system was investigated under various aeration rate and membrane inclination. The teat solutions were the aqueous solutions of PMMA and dextran T500. Experimental results show that aeration enhanced the permeate flux of PMMA solution more signific

Adsorption-membrane hybrid systems present an interesting alternative for the treatment of contaminated waters. This study aims to understand the role of NOM on membrane performance and on removal of pharmaceuticals during the combined application of powdered activated carbon and submerged membranes

Interactions between dissolved organic substances (dissolved organic matter and two model substances), ions (Na+ and Ca2+) and the membrane surface were investigated using a submerged membrane module. The membrane permeability, the fouling formation and the rejection were significantly influenced by

In this study, hydrodynamics and physiology of microorganisms were investigated in a new type membrane bioreactor, MHCR, which is a membrane coupled HCR (High performance Compact Reactor) having very high COD removal efficiency. The degree of interference caused by inserting a submerged membrane was

Fully submerged laboratory scale hollow fiber microfiltration module was used to treat a food industry wastewater in Malaysia. Permeate extraction was carried out continuously under a suction pressure not exceeding 0.9 bar. The module is aerated from beneath the microfiltration module to provide the

Partial nitrification is required before transporting secondary treated wastewater by pipe, which is common in most schemes of wastewater reclamation for irrigation. Sulfide, generated in the anaerobic conditions of the pipe, induces toxicity, corrosion and unpleasant odours. However, a low nitrate

Water in many areas of Australia is scarce and of poor quality. In some areas high levels of treatment are required either due to contamination of waters or due to high salinity. Nanofiltration (NF) and low-pressure reverse osmosis membranes are well-recognized technologies to treat waters of qualit
