Efficiency of Coagulation/Flocculation for the Removal of Complex Mixture of Textile Fibers from Water

Synthetic fibers enter wastewater treatment plants together with natural fibers, which may affect efficiency, a fact not considered in previous studies. Therefore, the aim of present study was to evaluate efficiency coagulation/flocculation process for removal mixture textile from different water matrices. Natural and synthetic (100 mg/L; cotton, polyacrylonitrile, polyamide) were added matrix, surface laundry subjected experiments ferric chloride (FeCl3) polyaluminum (PACl) under laboratory conditions. In both coagulants found be effective, FeCl3 having lesser advantage, removing almost completely (up 99% at concentration 3.94 mM). water, all dosages had approximately similar high values, coagulant resulting complete removal. effluent, presence surfactants is thought coagulation efficiency. PACl effective wastewater, lowest being 89% efficiencies. organic matter bicarbonates showed positive effect on water. better performance coagulating while negative
