The pretreatment of raw seawater is necessary to minimize the organic fouling of seawater reverse osmosis (SWRO) membranes. To predict the membrane fouling of the pretreated seawater, the modified fouling index (MFI) with ultrafiltration (UF) was investigated in terms of molecular weight distributio

The conventional treatment for production of drinking water from surface water generally consists of coagulation, flocculation, sedimentation and sand filtration. One of the main disadvantages of the conventional process combining sedimentation and filtration is the rather long residence time. This

This paper discusses the aeration aspect of an ultrafiltration application involving immersed membranes creating an airlift pattern. The continuous aeration commonly used with immersed membranes to mitigate the effects of fouling was compared with several new aeration configurations. These new aerat

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

The purpose of this study is to investigate, through fractionation experiments, the efficiency with which secondary effluents can be treated using UF and MF membranes alone or coupled with coagulation and/or adsorption. The results obtained prove that there are two mains fractions in a secondary eff

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
