Pre-treatment of textile wastewater in Van Phuc handicraft village by coagulation process
Handicraft textile production of Van Phuc village in Vietnam has released polluted substances into Nhue River. This problem needs to solve by proper methods to treat textile wastewater. coagulation is considered tobe a suitable process with the conditions of Van Phuc village. This paper concentrates on investigating the settling characteristics and removal efficiency of pollutants in wastewater. Different parameters of the treatment process were examined including PAC concentration, coagulant aids concentration, pH, COD values of wastewater. IN this regard, the treatments favors the utillzation of PAC with A101. Moreover, settling characteristics of flocs were studied in a laboratory scale by settling column unit to apply for designing large scale settling tank
