Nitrification Inhibition by Heavy Metals in Activated Sludge Process
Nitrification is the most sensitive part in the biologic nutrient removal of wastewaters, since the growth rate of nitrifying microorganisms is very lower and strongly dependent on temperature, substrate concentration, oxygen content, pH, and the presence of inhibiting components. This review addresses the nitrification inhibition by heavy metals. This inhibition can be quantified by different ...
متن کاملAdsorption and toxicity of heavy metals on activated sludge
The adsorption of Cu, Cd, Ni, Zn, and Cr from synthetic solutions on powdered activated carbon (PAC), activated sludge, and dried sludge were investigated under laboratory conditions to assess its ability to remove heavy metals. The adsorption efficiency increased rapidly within the first 30 min and then slowed down as it approached a steady state after 5 h of contact time. The results showed t...
متن کاملPerformance Evaluation of Combined Process of Powdered Activated Carbon-Activated Sludge (PACT) in Textile Dye Removal
Introduction: The Powdered Activated Carbon Treatment (PACT) has been proposed as an alternative in wastewater treatment and wastewater biomass protection against toxic substances. This study aims to evaluate PACT performance in treating dyes, acid orange, and remazol brilliant reactive blue. Materials and Methods: This empirical- applied research was carried out in pilot scale in which differ...
متن کاملAdsorption of heavy metals by EPS of activated sludge.
Extracellular polymeric substances (EPSs) were extracted by high-speed centrifugation at 20,000 G for 30 min from an activated sludge treating municipal wastewater. Each gram of sludge, as measured in volatile suspended solids (VSS), contained 7.3 mg of EPS, including 6.5 mg of protein (EPSp) and 0.8 mg of carbohydrate (EPSc). The EPSp had a mean MW of 2.0 x 105; about 18% of EPSp had MW over 5...
متن کاملInhibition of activated sludge respiration by heavy metals
Inhibition of the respiration microbial activity in the activated sludge caused by heavy metal concentrations (Cr, Cd, Cu and Ni) was studied by means of respirometric method using Strathtox respirometer (Strathkelvin Glasgow).The studied sludge samples were obtained from the two waste water treatment plants with different types of pollution (municipal waste water and domestic waste water). Key...
