textile industry is the major source of water consumption and wastewater pollution.there are various treatment techniques to remove textile wastewater pollution. coagulationflocculation is a widely used process to remove pollution due to suspended particles. in this research, different coagulants like alum, lime, fecl3, feso4 and mgcl2 were applied to select the suitable ones with optimum remov...

the textile industry has long been one of the largest of water users and nolluters and there has been little success in developing low cost treatment methods , which the industry urgently needs to lessen the pollution loads it discharges to streams. the obiective of this preparatory study was to determinen the effects o f coagulants and aid coagulant s as alum, ferrous sulfate , ferric sulfate ...

In water scarce countries such as Eritrea, maintaining brewery industry remain ever challenging task. Currently, Asmara breweries is the only beer producing factory consuming 8.46 L of per every produced which notably higher than Brewer’s Association (BA) benchmark and consequently generates 7.53 wastewater/L beer. Bottle cleaning activities ascertain ample effluent bases. Wastewater from bottl...

Two coagulants, aluminum sulfate and ferric chloride, were tested to reduce natural organic matter (NOM) as a pretreatment prior to polyvinylidene fluoride (PVDF) microfiltration (MF) membranes for potable water treatment. The results showed that the two coagulants exhibited different treatment performance in NOM removal. Molecular weight (MW) distributions of NOM in the tested surface raw wate...

The use of synthetic coagulants is not regarded as suitable due to health and economic considerations. Studies were carried out in laboratory scale on deionised water containing synthetic turbidity of kaolinite. Experiments were carried out in four turbidity ranges: 10, 50, 500, 1000 (NTU) and the pH range 5-8. The efficiency of moringa oleifera seed extract and polyaluminum chloride was examin...
