A Horizontal Centrifugal type of pump in Stainless Steel construction has been provided for supplying Raw water to Pressure Sand Filter Unit. Necessary Suction / discharge pipe work in Upvc construction with isolation valves are also provided to Unit.
Raw Water is first filtered by filtration unit. Pressure Sand Filter Unit is provided for removal of suspended matters & turbidity from raw water. PSF Unit is a FRP vertical Pressure Vessel. Internally, it is fitted with bottom collecting system. Uniform grades silica quartz sand is charged on the supporting media of pebbles and gravels. This unit is fitted with upvc frontal pipe work and Multiport Valve externally. During service cycle water is passed in down ward direction through sand bed, thus entrapping suspended matter & turbid particles. Over a period of time, sand bed gets chocked due to suspended matters resulting higher pressure drop and lesser floe. At this stage filter bed need to be backwashed. Backwashing is continued for about 10- 15 minutes or till the effluent coming out is clear For Rinsing of Sand Bed: Service water is passed in down ward direction to settle down the sand bed. The effluent water is drained for about 5 minutes time to ensure all unclear water is drained down.
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.
The regeneration involves backwashing & rinsing of Carbon Bed. Over a period of time, life of carbon gets exhausted which can be checked during laboratory testing. Generally carbon is replaced once in a year.
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.
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.
