Ultra-filtration is a process that falls in the membrane processes category. The principle is based on the filtration of raw water through a partition of a given pore size. A process that uses a partition with pore sizes on the order of tenths to hundredths of µm can be designated as ultra-filtration.
Ultra-filtration removes almost all undissolved substances from the treated water along with most microbial contamination, namely bacteria and viruses. The treated water is free of the colloidal particles and humic substances present, for example, in most surface water in the Czech Republic. The advantage is the low amount of added auxiliary chemicals such as coagulants or sanitary safety products, and low consumption of wash water. Another indisputable benefit is the possibility to use ultra-filtration to produce drinking water from surface water, such as a river. Ultra-filtration is also used as a pre-treatment for reverse osmosis stations, which reduces the risk of blockage by colloidal substances and thus prolongs the life of the membrane modules.
G-servis Praha is capable of designing and making an ultra-filtration unit for you according to your requirements, taking into consideration the quality of the input water. The output of ultra-filtration stations is highly variable, with the option of dimensioning it in a range from 0.2 m3/h to several tens or hundreds of m3/h.
