Disinfection by-products (DBPs) have heterogeneous structures which are suspected carcinogens as a result of reactions between NOMs (Natural Organic Matter) and oxidants/disinfectants such as chlorine. Because of variability in DBPs characteristics, eliminate completely from drinking water by single technique is impossible. The current article reviews removal of the precursors and DBPs by diffe...

Our objective was to determine if annatto color or bleaching had any influence on ultrafiltration (UF) flux during production of 80% whey protein concentrate (WPC) or 80% serum protein concentrate (SPC). Cheddar cheese whey (18 vats using 900 kg of whole milk each) and microfiltration (MF) permeate of skim milk (18 processing runs using 1000 kg of skim milk each) were produced. The 18 runs were...

There are many water quality characteristics which could influence the filterability of biologically treated effluent from Melbourne's Western Treatment Plant (WTP). Statistical correlation was used to identify the key water characteristics affecting the microfiltration (MF) and ultrafiltration (UF) filterability in terms of permeate volume of the treated effluent. The models developed showed t...

The effectiveness of microfiltration (MF) and ultrafiltration (UF) for nutrient recovery from a thin stillage stream was determined. When a stainless steel MF membrane (0.1microm pore size) was used, the content of solids increased from 7.0% to 22.8% with a mean permeate flux rate of 45L/m(2)/h (LMH), fat increased and ash content decreased. UF experiments were conducted in batch mode under con...

In the era of freshwater scarcity, world seeks to limit overexploitation all accessible resource and also recover potable water by treating wastewater. Various domestic, agricultural industrial activities lead in generating high amount wastewater from which can be recovered for human needs. Over many years, conventional filtration process has gained success some extent effluents treatment dispo...

In Project WASTEC, an experimental Reverse Osmosis (RO) desalination system was developed. It serves as a platform for testing new technologies. For this system, we solved two problems, which are described in paper. Firstly, developed and investigated strategies scheduling chemical enhanced backwashing cleaning secondly, due to the nature of project, several technological developments with resp...

Membrane filtration processes like microfiltration (MF) and ultrafiltration (UF) are proven to be effective in industrial wastewater treatment, including oil-water separation, as they generate suitable quality permeate for water reuse applications. Various research efforts have been conducted areas of developing and/or modifying commercial MF/UF membrane materials through synthesizing new advan...

background: onchocerciasis is endemic in the imo river basin, nigeria. this study was aimed at assess­ing the prevalence and intensity of microfilaria of onchocerca volvulus in the area. methods: a cross-sectional study was carried out in the okigwe local government area, imo state, nige­ria. two skin snips (one from the waist and another from the shoulder) were taken from 1024 individu­als exa...

New regulations aimed at curbing the problem of eutrophication introduce limitations for traditional ways to use by-product anaerobic digestion—the digestate. Hydrothermal carbonisation (HTC) can be a viable way valorise digestate in an energy-efficient manner and same time maximise synergy terms recovery water, nutrients, followed by more efficient remaining carbon. Additionally, hydrothermal ...
