SBR treatment of tank truck cleaning wastewater: sludge characteristics, chemical and ecotoxicological effluent quality

Chemical Cleaning of Utafiltration Membrane after Treatment of Oily Wastewater

SBR Technology and Role of Aerobic Granular Sludge in Biological Treatment of Wastewater

Urban centers are unambiguously discharging wastewater in the natural streams, lakes, ponds and for irrigation in the agricultural fields. In the early stages of human civilization, wastewater discharges did not pose problem to water bodies as the nature had the capability for degradation and restoration of the quality of water to its normal condition.The key challenges towards better managemen...

Comparison of dye wastewater treatment by normal and anoxic + anaerobic/aerobic SBR activated sludge processes.

In this research, the effects of different color intensities, anoxic + anaerobic times and types of substrate on color removal effectiveness were studied using 16-litre bench scale sequencing batch reactor (SBR) anoxic + anaerobic/aerobic models. The systems were fed with a synthetic wastewater containing 500 mg/l of COD, 50 mg/l of N, 15 mg/l of P along with 10, 40 and 80 mg/l of reactive diaz...

Characteristics and disposal options of sludge from a steel mill wastewater treatment plant

In the present study, sludge from a steel wastewater treatment plant (SWWTP) was analyzed regarding its physicochemical characteristics and metal contents, and disposal options. For these purposes, grab sampling was used to collect 18 slurry and 18 cake sludge samples in 6 mouth (May-October 2012). Mann-Whitney U test, one sample T-test and Wilcoxon signed rank test were applied to analyze the ...
