The effect of different hydraulic cleaning methods was investigated in terms of flux decline and resistance using the cross-flow UF unit. The use of varied production intervals, varied ratios of periodic relaxation and the use of a periodic high-rate crossflow were investigated. This cleaning method

This study aims at identifying the effect of pretreatment such as flocculation and/or adsorption on the performance of crossflow microfiltration (CFMF). CFMF performance was studied in terms of critical flux. The results indicated that: (1) flocculation alone as a pretreatment could effectively remo

This study investigates the performance of CFMF process with flocculation pretreatment for NOM removal using hematite as a flocculent. Spiral flocculator consists of rapid mixing and slow mixing units. The presence of rapid mixing prior to slow mixing enhances removal performance of the treatment sy

In this study, a new design of static floating medium flocculator was examined for its ability to remove suspended solids, organics and phosphorus. The floating medium flocculator also produced uniform microflocs, which could be removed easily by cross flow microfiltration. Flocs formed enhanced the
