Drinking water production

A large-scale ultrafiltration (UF) system integrated with coagulation was applied to produce drinking water from the highly turbid Taihu River. This UF installation could produce 10,000 m3 drinking water per day. In this study, the effect of FeCl3 coagulant on the performance of the UF system was ev

Surface water was purified by ultrafiltration membrane to produce drinking water. The membrane flux decreases with increasing turbidity and there is a somehow linear relationship between membrane flux and the log of turbidity. Mathematical model was built to predict the membrane flux based on this.

Ultrafiltration of Binxian reservoir (near Harbin in China) water to produce drinking water was investigated in this study. Membrane flux declined with temperature coming down. Using coagulation before UF not only increases the permeate flux, but also retards the permeability decline. In comparison

Electrodialysis (ED) is applied in Japan for seawater concentrating to ca. TDS 200 followed by thermal concentration and salt crystallization. A partially desalinated water (ED diluate) is obtained at the same time. Its further desalination for potable water production may be considered to decrease

The share of electrodialysis in seawater desalination is very small in contrast to reverse osmosis. It is stated that ED may compete with RO in the range of feed water salinity up to 8–10 g/L only because ED desalination cost is proportional to the amount of salt, which must be carried through the m

The aim of this work is to develop a predictive control algorithm to improve the productivity of an ultrafiltration pilot plant producing drinking water from surface raw water. The objective is to avoid irreversible fouling, that means to get a constant quality of the membrane after backwash and at
