Coagulation

This study evaluates the factors affecting pretreatment conditions for hybrid UF membrane processes for reuse of secondary effluent from the sewage treatment plant. The experimental results obtained from the ultrafiltration (UF) membrane process showed that the particles of the size range between 0.

The objective of this study is to evaluate the effect of electric fields application for the reduction of membrane fouling, the inactivation of microorganisms and the enhancement of particle coagulation. It was found that electric fields treatment prior to microfiltration showed in large quantity of

The results of studies are presented on the treatment of natural waters with a high content of organic compounds. The research involved unit processes of coagulation, microfiltration, and the hybrid process coagulation– sedimentation–microfiltration. In the membrane filtration process 19-channnel ce

Gas-filled membrane absorption has been used to remove cyanide from different cyanide containing wastewaters. In this study, cyanide removal from an industrial praziquantel wastewater has been investigated. The wastewater contained a high cyanide concentration and turbidity due to the presence of li

This study attempted to identify fouling-causing material during membrane filtration of surface water. For this purpose, two different coagulation conditions were designed: the optimum removal of turbidity-causing particles (Case I) and the optimum removal of organics (Case II). It was hypothesized

Unplanned transportation systems near water resources have not only caused a dramatic population increase in the water catchment areas of Istanbul but also created major water pollution problems as a result of illegal settlement and industrial and agricultural activities. In this study, water qualit

We considered the treatment of secondary effluent by coagulation–adsorption coupled with ultrafiltration. Tests were performed on the secondary effluent of the wastewater treatment plant at Staoueli (Algeria) where the average chemical oxygen demand (COD) was 46 (mg O2/L) and turbidity, 16 NTU. The

Cross-flow microfiltration alone or associated with ultrafiltration or coagulation was conducted to investigate the efficiency of this process in the reducing of chemical oxygen demand (COD) and proteins (Npr) in the waste waters produced from cuttlefish conditioning and freezing process. The study

The objectives of this research were to evaluate two different processes using for wastewater reclamation in a hightech industrial park area in Taiwan. The major units of the first AC–RO–IE system included sand filter, an activated carbon (AC) bed, microfiltration module, a reverse osmosis (RO) memb
