ACTIVATED CARBON FILTER

Activated Carbon can remove Chlorine, Odour, & Colour while passing the water through carbon bed along with Odour & Colour. This Carbon granules having larger surface area and specific property to absorb organics. ACF Unit is a FRP vertical pressure vessel. Internally it is fitted with strainer on bottom collecting system. The unit is fitted with upvc pipe work. During service cycle water is passed in down ward direction through Carbon Bed, which removes Chlorine & Odour from water.

This kind of Micron Cartridge Filter having Series of filtration with the 20 Micron , 10 Micron , 5 Micron , 1 Micron & 0.2 Micron Nominal & Absolute Micron Cartridge. This is a Consumable Cartridge and should replace it after Days of operation.

ULTRA VIOLET STERILIZER

The water to be disinfected, is passed through U.V. System, which consists of U.V. Tubes which radiates high intensity Ultra Violet Rays, which in turn kills the microorganisms. This system consists of a S.S finished surface housing with Ultraviolet Lamps fitted in it. The water to be treated is surroundings this tubes during treatment. An electrical system is provided for production of high voltage required for U.V. Rays generation.
