The fate of polar organic micropollutants (logDOW (pH 7) between −4.2 and +3.5) during riverbank ,filtration, (RBF) at the river Thur was studied using both spatiotemporally resolved sampling and single-well push–pull tests (PPT), followed by LC-MS/MS analysis. The Thur is a ,dynamic, prealpine river with an alluvial sandy-gravel aquifer, which is characterized by short groundwater travel ...

Physicochemical ,filtration, is a favoured method for removal of bacteria from the potable water and ,wastewater, because of its simplicity, high efficiency, and low-cost operation. The governing mechanism of this ,filtration, technique is adsorption and this process does not produce by-products as is found in chemical disinfection process used for water purification [ 5 ].

In fact, the treatment of ,wastewater, might be a net energy producer (Switzenbaum 1984). Originally, anaerobic treatment was the preferred process for domestic ,wastewater, management. Imhoff modified the septic tank for ,wastewater, treatment in Germany, and by 1933 the Imhoff tank was used by over 240 towns in Germany.

The particular ,wastewater, was characterized by oil and grease (O & G) concentrations as high as 6 g/L, COD of 51 g/L, BOD of 16 g/L and volatile fatty ,acid, (VFA) of 8.3 g/L. The use of a submerged membrane bioreactor for the treatment of industrial oil contaminated ,wastewater, was investigated using microfiltration hollow fiber membranes by [56] .

NF experiments with MF-prefiltered secondary effluentsThe experiments with MF-prefiltered secondary effluents (TSS = 5.1 mg/l, COD = 55.6 mg/l) lasted from few days up to 12 days. During 12 days experiment the rejection of the organic matter and brine were steady along the experiment and were about 70% and 60%, respectively.
