 3. Reverse Osmosis Plant(RO): We are one of the leading reverse osmosis plant manufacturers and suppliers of RO plants. These Silver Stream Reverse Osmosis Filter System make use of special semi permeable TFC membrane Filter as well as TFC/Thin Film Composite Filters that reject higher percentage of dissolved solids including sodium, the smallest of molecules present in water. With the unit designed to efficiently change normal tap water into fine quality drinking water, the systems greatest advantage is it allows no harmful chemicals to be carried over to final water

Advantages

• Silver Stream Reverse Osmosis Filter System providing unlimited supply of fresh drinking water
• Capability to deliver portable water that is free of harmful chemicals and pathogens
• Providing complete safety in form of purified water that safeguards from diseases like dysentery, typhoid, jaundice and cholera

4. Ultrafiltration Water Treatment:      The theory of ultrafiltration is not new. What is new is its successful, practical application to the separation of contaminants such as bacteria and organic colloidal impurities.

In the various separation systems listed in Figure 1, the ultrafiltration membranes used are non cellulosic organic polymers having an asymmetric, extremely thin (5-micron) surface layer or skin and a porous substructure of the same material. The total membrane thickness is only 6 to 8 mils; consequently, to handle the 20 to 50 psi used in water treatment, the membranes are reinforced with a nonwoven paper material for added mechanical support. Separations take place at the membrane surface, not within the substructure

In the tests reported here, the ultrafiltration systems comprise a series of modules, each providing 60 square feet of surface area. (Each module contains three replaceable cartridges, and each cartridge contains 20 square feet of membrane housed in a glass-reinforced polyester

Inherent in the use of membranes for phase separation is the fundamental problem of concentration polarization. The separation of one species from another at the surface of a membrane results in local concentration of the rejected species at the membrane surface. This concentration in turn causes an increase in density and viscosity of the laminar sub layer at the surface of the membrane. Associated with these changes is the decrease in membrane flux. The more severe is the polarization, the poorer is the long-term flux characteristics of the membrane.
