摘要：

The paper presents the results of water treatment investigation, using UF/MF and a hybrid process coagulation-UF/MF. The experiments were conducted using capillary modules made of polyethersulfone (PES) for ultrafiltration and of polypropylene (PP) for microfiltration. Two coagulants, i.e. iron chloride (FeCl(3)-6H(2)O) and aluminum sulfate (Al(2)(SO(4))(3)center dot 18H(2)O), were used during the coagulation. The hybrid water treatment process was carried out in coagulation-sedimentation-MF/UF and "in-line" coagulation (without sedimentation)-MF/UF systems. Unlike a direct UF/MF, the hybrid processes allow an improvement in water quality and reduction in fouling intensity. UF efficiency can be predicted employing relaxation and resistance models. The mechanism of fouling based on Hermia's equation was determined.
