Effects of nanobubble aeration in oxygen transfer efficiency and sludge production in wastewater biological treatment
Low efficiency of conventional aeration techniques and the excessive production and disposal of sludge are great concerns in biological wastewater treatment systems. The present study aimed to evaluate the active sludge method using batch reactors under continuous operation to determine the efficiency of aeration and sludge production through microbubble and nanobubble aeration. The results ind...
متن کامل"study of the biological treatment of industrial waste water by the activated sludge unit"
the activated sludge process simply involves bringing together wastewater and a mixed culture of microorganisms under aerobic conditions. the system usually includes a secondary treatment given to the settled sewage, and requires an environment in which active microorganisms are maintained in intimate contact with wastewater in the presence of sufficient oxygen. in this study, the treatment of ...
متن کاملEffects of pistachio processing wastewater on treatment efficiency of urban wastewater using activated sludge process
Background: In this study, the effect of wastewater produced by pistachio processing in processing terminals on wastewater treatment plants with activated sludge process was investigated. Methods: The pilot of activated sludge was constructed at the laboratory scale similar to wastewater treatment plant in Kerman and it was investigated in different ratios of the wastewater of pistachio proces...
متن کاملExperimental Comparison of Two Modifications of Activated Sludge for Treatment of Furfural-Containing Wastewater
A case study is presented in which two modifications of activated sludge treatment of complex chemical wastewater are experimentally compared: a combination of common activated sludge with powdered activated carbon treatment (PACT), and bioaugmentation of activated sludge treatment (BAST). Industrial wastewater of Pars Oil Refinery that was passed through an oil recovery stage was used to inve...
