Ultrafiltration

• T he investigations substantiated the thesis that t he hydrophilicity of the membranes noticea bly affects the efficiency of treating water p olluted with natural organic matter by u ltrafiltration. • S trongly hydrophilic membranes (made of r egenerated cellulose) displayed a high p ermeability a

Bovine blood is a potentially important source of raw material for the alimentary industry and many pharmacochemical industrial products. Different fractions obtained with the application of membrane separative techniques were studied, orientating our work to obtain bovine seroalbumin (BSA). Pretrea

Groundwater is still one of the main sources for the production of drinking water. In the preparation of drinking water, the groundwater is first aerated and then filtered through a sand filter in order to remove Fe, Mn, NH4 and methane. After saturation, these sand filters have to be backwashed per

Among the desalination technologies available, reverse osmosis is currently considered as the most economical process. However, while RO membranes have been continuously improved over the years, they have had one major shortcoming; the susceptibility to fouling. Indeed, it appears that RO technology

The paper describes a case of rationalization of the use of the waters of a textile factory located in the northern part of Italy. The water used in the factory comes from deep wells located about 170 m below the level of the factory. The yearly used amount of water is about 540,000 m3. Inside the f

Most of the municipal sewage treatment plants (MSTPs) being operated in Korea were designed for wastewater with average concentrations of municipal sewage. However, they are in fact being operated at low organic loading. Thus, most of the secondary small-scale sewage treatment plant cannot satisfy t

With an ever-growing world-wide demand for water and decreasing availability, emerging technologies such as ultrafiltration (UF) hold the key to future water treatment. Two applications to use unconventional sources for water production are described. The reuse of effluent of wastewater treatment pl
