Ultra filtration is a unique pressure-driven physical separation process in which the water is passed through porous (partially permeable) membranes with pore sizes in the range of 0.1 to 0.01 micron. These membranes are in the form of long hollow fibers. The result is high pure water free from physical and biological contaminations.
WTE UF Plants are designed for a variety of industrial & commercial applications requiring high quality equipment with a fast delivery and competitive price. These pre-engineered, pre-assembled and factory tested units minimize installation and start-up time. With simple utility connections and easy to set up controls, the UF plant in Mumbai is ready for quick on-line service. The control system is an advanced microprocessor based system that is very easy to use.
Ultra filtration (UF) is an important purification technology used for the production of high-purity water in the many industries. When strategically combined with other purification technologies in a complete water & Wastewater system. UF membranes of UF plant used to remove high molecular-weight substances, colloidal materials, silt, turbidity, organic / inorganic polymeric molecules, algae, particulate matters, suspended solids and all microorganisms from Water & Wastewater.
Treatment of feed prior to the membrane is essential to prevent damage to the membrane and minimize the effects of fouling which greatly reduce the efficiency of the separation. Types of pre-treatment in Ultra Filtration Plant manufacturer in Pune are often dependent on the type of feed and its quality. For example in wastewater treatment, household waste and other particulates are screened. Other types of pre-treatment common to many UF plant in Mumbai include pH balancing and coagulation. Appropriate sequencing of each pre-treatment phase is crucial in preventing damage to subsequent stages. Pre-treatment can even be employed simply using dosing points.
Ultra filtration system of Ultra Filtration Plant manufacturer in Pune can either operate with cross-flow or dead-end flow. In dead-end filtration the flow of the feed solution is perpendicular to the membrane surface. On the other hand in cross flow systems the flow passes parallel to the membrane surface. Dead-end configurations are more suited to batch processes with low suspended solids as solids accumulate at the membrane surface therefore requiring frequent back flushes and cleaning to maintain high flux. Cross-flow configurations are preferred in continuous operations as solids are continuously flushed from the membrane surface resulting in a thinner cake layer and lower resistance to permeation.
Cleaning of the membrane of UF plant is done regularly to prevent the accumulation of foulants and reverse the degrading effects of fouling on permeability and selectivity.
Regular backwashing is often conducted every 10 min for some processes to remove cake layers formed on the membrane surface. By pressurizing the permeate stream and forcing it back through the membrane, accumulated particles can be dislodged, improving the flux of the process. Backwashing is limited in its ability to remove more complex forms of fouling such as biofouling, scaling or adsorption to pore walls.
These types of foulants require chemical cleaning to be removed. The common types of chemicals used for cleaning in Ultra Filtration Plant manufacturer in Pune are:
Factors Affecting the performance of UF
Performance of UF System
Ultrafiltration is a low-pressure membrane process used to separate bacteria, viruses, and high molecular weight compounds colloidal and particulate matters from a feed stream. Ultra Filtration Plant in Pune has larger pores and high permeability with less osmotic effects that allows Ultra filtration plant to operate at relatively lower pressure than nanofiltration and reverse osmosis and is therefore it is least costly to operate.
Ultra filtration plant is considered more effective as compared to traditional water filtration. An Ultra Filtration Plant in Pune is used in turbidity removal; in addition, it also removes bacteria, virus, microorganisms, particulate material, and natural organic materials from the water.
Ultrafiltration is used to recycle flow or add value to later products and more. In many cases Ultra Filtration Plant in Pune (UF) is used for prefiltration in reverse-osmosis plants to protect the reverse-osmosis process. UF plant in Mumbai is an effective means of reducing the silt density index of water and removing particulates that can foul reverse osmosis membranes.
Ultra filtration plant is frequently used to pre-treat surface water, seawater and biologically treated municipal water upstream of the reverse osmosis unit.
