Biodegradation

Laboratory scale experiments were conducted to investigate the removal mechanisms of trace organic contaminants using a submerged MBR system. The system was equipped with a Zenon ZW-1 membrane module. Bisphenol A and sulfamethoxazole were selected as model trace organics representing endocrine disru

Research on the treatment of two kinds model urban wastewater (W1, W2) with the contents of edible oil were carried out by activated sludge method in the membrane bioreactor. Biodegradation degree for readily and sparingly biodegradable compounds was determined on the basic of COD, BOD and TOC remov

– The effect of COD/O3-N ratio on the biodegradation of complex phenolic mixture was studied in bench scale hybrid upflow anaerobic sludge blanket (HUASB) reactors. HUASB reactor is a combination of a UASB unit at the lower part and an anaerobic fixed film at the upper end. The aim of this study was

Tests of the biodegradation of the azo dyes Reactive Black 5 and Reactive Yellow 145 confirmed the low biodegradability of these components in the considered conditions, namely a strain of Pseudomonas fluorescens, cultivated at 25°C, an initial pH of 7 and in presence of a supplementary carbon sourc

The biodegradability of two petroleum fractions f1 (180–235°C) and f2 (235–350°C) with different boiling ranges has been studied by using pure cultures of Pseudomonas sp., isolated from the contaminated water of Algiers’ port. Experiments were carried out in batch cultures at two temperatures, 15°C
