Water treatment by ultrafiltration (UF) method

Информация о продукте

UF ultrafiltration is one of the newest water treatment methods that is widely used in industrial, domestic and agricultural sectors. Ultra-Filtration UF is designed based on the use of a the empty filter (membranes) that due to the very small diameter of the holes on the filter, has the ability to remove waste and contaminants in the water up to 99%. In the following, we will have a complete look at water purification by ultrafiltration method and the advantages and important points in using this equipment. Join Haft Industrial Group, a manufacturer of ultrafiltration water treatment packages. Due to the shortcomings of water treatment methods such as sand filter and bag filter and their inability to completely remove germs and viruses in water, a new method called ultrafiltration was introduced. In this method, with the help of empty polypropylene filters, water-suspended particles with a size of less than 0.02 microns can be completely removed. In other words, the use of filters or membranes with holes with a diameter of 0.01 microns makes it impossible for all particles smaller than 0.02 microns to pass through the water, and as a result, the water is purified to 99.99%. Excessive water consumption for industrial, domestic and agricultural use, as well as declining rainfall in recent years, has raised many concerns around the world. In addition, in many areas and cities, purified drinking water is difficult to obtain and may even contain a lot of salts. For this purpose, various methods for water treatment have been introduced, which one of the bests is ultrafiltration. With this method, not only industrial water, but also in the production of drinking water, can produce from impure water the pure water which is away from any pollution, viruses and dangerous microbes. In order to better efficiency in the ultrafiltration method, it is necessary to pay attention to the features considered in the design and production of filters and membranes, standards and the quality of water entering the device. In general, based on a regular standard, the quality of water entering the UF is as follows: COD or oxygen demand less than 60 mg / lit Maximum pH in the range of 2 to 11 units Oil in water less than 2 mg / lit Maximum water turbidity, 300 NTU Maximum Solid suspended particles in water less than 100 mg / lit Lack of attention to the quality of the water entering the UF causes the membranes or filters to become dirty very quickly and lose their efficiency and reduce its lifespan.
