Isolation and characterization of bacteria from extended aeration wastewater treatment plants / Randy Chin Kok Fei

In this study, three different wastewater treatment plants (STP1, STP2 and STP3) were sampled in Klang Valley. STP1 exhibited the best activated sludge health with healthy Sludge Volume (SV), Mixed Liquor Suspended Solids (MLSS) and Mixed Liquor Volatile Suspended Solids (MLVSS). STP2 were constantl...
