Filtration processes varies from plant to another, while it’s crucial among them. Main purpose of filtration is to remove obstacles and particles from the raw water as well as Total Dissolved Solids (TDS). Filtration divides into several categories. General purpose filtration which includes sand, carbon and birm filters. Another category is the advanced filtration using ultrafiltration and nanofiltration. UUES provides a wide range of filtration products to its customers, considering cost effectiveness, best quality and challenging delivery time, in addition to the extraordinary before and after sale services.
Sand and Carbon Filters:
Most common types of sand and carbon filters are gravity and pressurized sand filters. Every type has certain applications and duties must be considered in design and construction criteria. Sand filters are ideally responsible for removing suspended solids from water, while carbon filters are ideally responsible for certain chemicals, particularly organic chemicals, from water.
UUES presents between its customers hands the birm filters’ solution for iron and manganese removal. Birm is an efficient and economical media for the reduction of dissolved iron and manganese compounds from raw water supplies. It may be used in either gravity fed or pressurized water treatment systems. Birm acts as an insoluble catalyst to enhance the reaction between dissolved oxygen (D.O.) and the iron compounds. The physical characteristics of Birm provide an excellent filter media which is easily cleaned by backwashing to remove the precipitant.
Ideally ultrafiltration is an effective means of reducing the Silt Density Index (SDI) of water, and removing particulates that can foul reverse osmosis membranes. Ultrafiltration is frequently used to pretreat surface water, seawater and biologically treated municipal water upstream of the reverse osmosis unit.
Nanofiltration is a new technology currently in hand with UUES. Nanofiltration is a membrane filtration-based process which been used most often with low TDS water supplies. Recently nanofiltration is being used for industries such as milk and juice production. Nanofiltration design and applications varies between an industry to another, and UUES now is ready to fulfil its customers requirement in term nanofiltration systems design, technical support and operation.
