Integration of alumina ultrafiltration membrane and palladium-catalyzed peroxymonosulfate for removal of organic micropollutants

Tian, He (author)

Organic micropollutants (OMPs) originate from organic chemicals such as drugs and pesticides that are widely used in human activities. OMPs are difficult to remove by conventional water treatment techniques, and hence continue to accumulate in natural water bodies. More effective methods need to be investigated for the removal of OMPs in...

Performance and membrane fouling of alumina UF membranes in treating nano-sized oil-water emulsions

LIU, HAO (author)

Ultrafiltration (UF) is an efficient and effective method of filtrating oil-in-water (O/W) emulsions. However, the favorable conditions of filtrating nano-sized O/W emulsions have not been investigated. This study investigated the influence of four different parameters including membrane pore size, cross flow velocity, pH and salinity on...

Predicting suspended ion exchange with PHREEQC

Schouten, Sander (author)

Natural organic matter is one of the key components to remove from source water during drinking water production. NOM not only negatively influences the colour, taste and smell of the water, it also decreases the effectiveness of common water treatment steps such as (membrane) filtration and UV desinfectation. A big fraction of natural organic...

Proof of concept design of a black water disinfection system for on board use on recreational vessels and yachts

Veel, Lucas (author)

There are more than 160,000 recreational crafts in the Netherlands with a toilet on board. It is forbidden to discharge blackwater into the environment from these crafts. Stricter enforcement of the law by the sealing of the valves of the external drain, leaves the owners of these crafts with a major problem. It is allowed, however, to treat the...
