The physicochemical wastewater treatment techniques are used as pretreatment, final treatment as well as specific treatment for wastewater reuse as processwater. Often used techniques in physicochemical wastewater treatment are flocculation,coagulation, flotation, neutralization, electroflotation, membrane technology-membrane filtration, NH3 stripper-absorbers and sludge treatment.
Physico-chemical analyses were carried out according to Standard Methods for the Examination of Water and Wastewater (1985). Nitrification unit A continuous-flow sand-bed was used for nitrification. It consists of a non- transparent, hard PVC tube of 150 cm length and 15 cm inner diameter coupled to a settling basin of 3.471 capacity.
