Ammonia Wastewater Treatment by Immobilized Activated Sludge

Effects 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...

Textile wastewater treatment: aerobic granular sludge vs activated sludge systems.

Textile effluents are characterised by high content of recalcitrant compounds and are often discharged (together with municipal wastewater to increase their treatability) into centralized wastewater treatment plants with a complex treatment scheme. This paper reports the results achieved adopting a granular sludge system (sequencing batch biofilter granular reactor - SBBGR) to treat mixed munic...

Experimental 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...

feasibility of using the dried sludge by municipal wastewater treatment with activated sludge process

background: using the sludge as fertilizer on farms is one of the options to dispose it, which due to its variety of pathogenic microorganisms, it may cause a wide range of bacterial and parasitic diseases in human and livestock. the purpose of this study is to investigate the feasibility of using dried sludge produced in municipal wastewater treatment processes to fertilize agricultural lands ...
