“…The resulting effectiveness is comparable to that found during the coagulation process, which may point to the fact that large molecular mass compounds were removed during coagulation, while medium molecular mass compounds were removed during adsorption [21], with compounds absorbing UV light dominating the fraction removed in both processes.…”

Abstract. The presence of organic substances in the water intaken for consumption could be hazardous to human health due to the potential formation of disinfection by-products (TOX). The study were carried out in the pilot surface water treatment system consisting of coagulation, sedimentation, filtration, ozonation, adsorption and disinfection. Due to continuous operation of the system and interference with the parameters of the processes it was possible not only assess the effectiveness of individual water treatment processes in removing TOX, but also on factors participating on the course of unit processes.

“…It was also observed that R f was greater for CFQ than for SW and CFS, but concentration polarization resistance (R cp ) and R t were lower for CFQ than for SW and CFS at 1 bar and 2 bar. The floc cake resistance is lower than the resistance due to the unsettled floc and the uncoagulated organics, as reported by Guigui et al (2002). The use of chitosan as a coagulant can lead to the formation of denser flocs.…”

“…Coagulation, which is regarded as an economical and efficient pretreatment method, has been widely used in drinking water and wastewater treatment. The actual effect of pre-coagulation on the permeability of the membrane depends on coagulation conditions, including coagulant types, dosage and mixing condition [21]. The coagulant directly affected the coagulation performance, and the coagulation performance directly determined the efficiency of water treatment [22].…”

a b s t r a c tThe aim of this study was to investigate the coagulation performances in different algal systems, and effects of algal morphology and composition of extracellular organic matter (EOM) on membrane flux were also investigated. The results indicated that Al 13 generated the largest flocs, and strength factor and recovery factor were also largest. The results of ultrafiltration experiments also showed that the floc size and the concentration of Soluble Microbial Products (SMP) may be the main decision factors in the membrane fouling process. Al species distribution was important in removing EOM in the coagulation process. SMP in EOM could be effectively removed by Al 13 and Al 30 , so the membrane fouling could be alleviated due to the larger removal efficiency of SMP. The roughness of the sediment layer formed by Al 13 was largest, and the sediment layer would adsorb and intercept more algae organic matter.
