Ultra filtration of water. Principle, Technology, Equipment
The ultra filtration systems presented in our store .
Depending on the pore size, membrane water treatment methods are divided into the following: ultra filtration , nano filtration and reverse osmosis . The main advantages of such water treatment methods
- continuity of work;
- environmental friendliness;
- reagent less process;
- full automation of the process.
Due to the ultra filtration (UV) membrane, impurities such as microorganisms, algae, and even most bacteria and viruses that are larger than 0.01 μm are screened out, which significantly reduces the turbidity and color of the water. UV cleaning often reduces oxidizability. Ultra filtration completely replaces the processes of sedimentation, deposition and microfiltration. In water treatment, hollow fiber membranes are widely used, in which the main element is a fiber with a diameter of 0.5-1.5 mm, in which the inner surface serves as an ultra-filtration membrane. To increase the filtering ability, the fibers are grouped into modules providing an internal surface of up to 50 sq.m. Ultra filtration of water , in contrast to Industrial Ro plant technology, brightens and disinfects water without changing the salt composition without the use of chemicals. In industrial conditions, the UV system operates with “dead end filtration”, i.e. in the mode without dropping the concentrate, which occurs due to the alternation of filtration and backwashing of the membrane. Part of the purified water is supplied in the opposite direction to remove accumulated contaminants. Adding a special solution to the wash water, which consists of detergents, improves water purification . This kind of flushing water, which has become a concentrate, averages 10-20% of the total water flow. If necessary, enhanced washing of membranes with circulating detergent solutions dramatically increases their resource ..
The uniqueness of ultra filtration is that it can be used to produce high-quality drinking water directly from a source with surface waters, because The UV membrane is an ideal barrier to most viruses and bacteria. This feature of ultrafiltration of water frees water from the need for primary chlorination, because disinfection of water takes place immediately before serving it to the consumer.
