Anaerobic treatment of a paper plant effluent
… produces paper by re-pulping waste paper. Effluent from the process has a Chemical Oxygen Demand (COD) concentration of approximately 4500 mg/l with a sulphate content of approximately 300 mg SO₄²⁻/l. The upflow anaerobic sludge bed (UASB) reactor was selected for the study. Important …

Heavy metal removal from bilge water by electrocoagulation treatment
… aluminum and carbon steel; flow rate of 1 L/min; effluent recycling and 7.5 amps; this optimal configuration achieved 99% of zinc removal efficiency, 70% of both, copper and nickel removal efficiency, and low operation costs. The current intensity did not have significance incidence on the removal …

Biological treatment and recycling of textile processing effluents
… culture system for the treatment of textile dye effluents. The bioprocess was optimised using biomass growth supports. The presence of a carbon source such as soluble wheat starch (0.2 % w/v) in dye solution media and effluent samples enhanced decolourisation. A polymer support (polyurethane …

The potential of immobilied algal cell systems for the removal of mercury from aqueous solution
… densities. Considerable cell leakage into effluent was measured. With agarose-immobilized cells, the use of high flow rates reduced mercury removal efficiency whilst lower flow rates. effluent recycling or extended operation times increased volatilization. Scanning electron microscopy …
