The paper reports on the results of treatment of wastewater from the bottling of water and soft drinks with a membrane bioreactor (MBR) pilot plant. The existing conventional activated sludge process could not produce effluent suitable for discharge due to significant fluctuations of wastewater comp

The combination of UVA radiation and ozone, in the presence of titanium dioxide, has been investigated as a potential destructive technology for the treatment of pesticide wastewaters. The contribution of single ozonation (O3), photolytic ozonation (O3/UV), and photocatalysis (TiO2/UV) to degradatio

Water content profoundly affects the efficiency of vertical flow constructed wetlands. Detailed vertical water content profiles could help to improve our understanding of the behaviour of these systems. In this study we tested a capacitance probe to measure water content in a vertical flow construct

This study was performed to evaluate the physicochemical properties of dissolved organic carbons (DOC) in the effluents coming from a clinoptilolite amended activated sludge with regard to various sludge retention times (SRTs) singularly run or in combination with a coagulation process. First, four

The TiO2/SiO2/Fe3O4 (TSF) photocatalyst was used for the treatment of synthetic dyes wastewater. Different operating conditions such as catalyst load, pH and dye concentration were investigated in order to determine the optimum operating conditions. The optimum operating conditions were found to be

Reverse osmosis (RO) is increasingly used as a separation technique in chemical and environmental engineering for the removal of organics and organic pollutants present in waste water. Treatment of organics by RO is dependent on many factors and hence developing a viable RO system involves extensive

This study provides information on the Cr(VI) adsorption potential of Turkish (Mihalıççık region) montmorillonite clay as an abundant, cost-effective and untried material. Batch adsorption trials of chromium were performed to investigate the effects of pH, contact time, and initial metal ion concent

Reactive extraction is a promising technique for the recovery of carboxylic acid from dilute aqueous solutions. Reactive extraction requires a proper combination of extractant and diluent which provides higher capacity and selectivity. The recovery of propionic acid by reactive extraction (present i

Arsenic in drinking water is a factor that has recently been shown to be a possible cause for an elevated bladder cancer risk in northern New England. More than 40% of the population in this region uses private wells as the primary drinking water source. Point-of-entry (POE) and point-of-use (POU) a

CO2 plasma was used to modify hydrophobic polypropylene microporous membranes to create hydrophilic surfaces. Structural and morphological changes on the membrane surface were characterized by X-ray photoelectron spectroscopy and scanning electron microscope. Membrane performance was tested with wat
