1, UF processes are currently limited by the high cost incurred due to membrane fouling and replacement. Additional pretreatment of feed water is required to prevent excessive damage to the membrane units.
2, Quartz Sand Filter
It uses quartz sand as filter medium, effectively intercept to remove the suspended solids in the water, organic matter, colloid particles, microorganism, chlorine, smelling and some heavy metal ions, etc., finally to reduce water turbidity, purify water quality.
3, Activated Carbon Filter
GAC(granular actitavted carbon) is used for both removing organic constituents and residual disinfectants (such as chlorine and chloramines) from water. We make GAC media always by coco nut shell which is the best quality media.
Activated carbon filter can effectively remove color, odor, residual chlorine, organic matter and heavy metals, synthetic detergent, such as bacteria, viruses and radioactive pollution.
4, Water softener
A water softener can be used to help prevent scaling in an RO system by exchanging scale forming ions with non scale forming ions. As with a MMF unit, it is important to have a 5 micron cartridge filter placed directly after the water softener in the event that the under drains of the softener fail.Water softener is used to remove calcium and magnesium, and some other metal cations in the hard water.
5, Ultrafiltration(UF)
Ultrafiltration (UF) is a variety of membrane filtration in which forces like pressure or concentration gradients lead to a separation through a semipermeable membrane.Suspend solids and solutes of high molecular weight are retained in the so-called retentate, while water and low molecular weight solutes pass through the membrane in the permeat (filtrate). This separation process is used in industry and research for purifying and concentrating macromolecular (103 - 106 Da) solutions, especially protein solutions.
UF can be used for the removal of particulates and macromolecules from raw water to produce potable water.
