Raw Water is first filtered by filtration unit in series prior feeding R.O. Plant. Dual Media Filter Unit is provided for removal of suspended matters & turbidity from raw water. DMF Unit is a SS vertical Pressure Vessel. Internally, it is fitted with bottom collecting system. A uniform grades silica quartz sand is charged on the supporting media of pebbles and gravels. This unit is fitted with SS 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 back washed.

When Pressure drop across the sand bed increases beyond the specified limit (0.5 kg/cm2) or quality of filtered water determinate, whichever is earlier. Regeneration involves backwash & rinsing of Sand Bed as below. For backwashing service water is passed in reverse direction of service cycle to loosen the filtering media bed. Due to this, entrapped suspended matters get free and comes out along with effluent water. Back washing 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.

Natural water may contain Color, Odour, Chlorine & Organics in different proportion, which is undesirable for potable application, and hence, it is necessary to remove the same from water. If raw water is chlorinated for die-infection, it is necessary to remove the free Chlorine feeding to R.O System. Chlorine being a strong oxidizing agent, it damages R.O. Membranes. Activated Carbon can remove Chlorine, Odour, & Color while passing the water through carbon bed along with Odour & Color. 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 SS frontal pipe work & MPV externally. A granular activated carbon is charged on the supporting media of Coarse & Fine Silex. During service cycle water is passed in down ward direction through Carbon Bed, which removes Chlorine & Odour from water.

when pressure drop across the Carbon Bed increased beyond the specified limit of (0.8 kg/cm2) or quality of filter water deteriorates, whichever is earlier the unit is isolated for regeneration. The regeneration involves, back washing & rinsing of Carbon Bed. Over a period of time, life of carbon gets exhausted which can be checked during laboratory testing. Particularly iodine value is most important for this application. Generally, carbon is replaced once in a year.

The Water Softeners are charged with a high capacity polystyrene bead cation exchange resin in sodium form. When hard water passes through this resin column, the hardness forming calcium and magnesium salts are replaced with sodium salts which do not possess any hardness properties. This softening process is continuous until the material is exhausted of sodium salts when it is regenerated with a solution of common salt.

This kind of Micron Cartridge Filter having Series of filtration with the 20 Micron, 10 Micron, 5 Micron, 1 Micron, 0.45 Micron & 0.2 Micron Nominal & Absolute Micron Cartridge. This is a Consumable Cartridge and should replace it after Days of operation. This for Extra Safety of your Product water as it comes through the followed filtration and there are some chances to slippages for any particles which can be stop through the Cartridge also 1, 0.45, 0.2-micron cartridge filter will also take care of Bacteriological growth up to 0.2 micron.

For Reverse Osmosis Process to take place feed pressure of water need to be raised. For this purpose, a Vertical Multistage Centrifugal High-Pressure Pump in S.S construction is provided R.O. System requires operating pressure of about 14-16 kg/cm2. High-pressure pump is fitted with S.S. discharge pipe work with necessary control valves. Necessary instruments like a High-Pressure Switch, Pressure Gauge and re circulation valves are provided for safer operation of system.

For safe operation of system following instruments are provide on Panel. Feed & Reject Pressure Gauge to indicate respective pressure of R.O. System. Feed & Reject Flow Indicator to indicate respective flow of R.O. System. T.D.S Meter to measure TDS of Raw & Treated water. High Pressure Switch for tripping high pressure pump in case of excessive feed pressure of R.O. System. Time Totalizer for counting working hours of H.P. Pump/ R.O. System.

Reverse Osmosis System rejects 97 – 99% of total dissolved solids by the principle of `Osmosis’. This system consists of a R.O. Module assembly mounted on S.S. Skid. High pressure rating FRP Pressure Vessel is fitted on the skid which houses spirally wound membrane elements in series.

In RO System feed soften water is divided into two streams viz Product & Reject water. Product water is treated water having lesser TDS. Reject water is highly concentrated water, which is not to be used for any purpose but drained. Feed water at elevated pressure is first fed to first Pressure Vessel; treated water is collected in center core tube. Treated water from each membrane is collected jointly in a common product water storage tank and reject is drained.

One No. of Treated water from R.O. System is stored in an our supplied a S.S. constructed storage tank of appropriate capacity. The tank is fitted with S.S. pipe work & isolation valves and suitable type of level indicator.

Transfer pump is provided in S.S. material of construction to feed the water in Post MCF.

During storage, atmospheric or any other contamination may take place in treated water. Hence, after passing water from R.O. System, water is once again passed through a micron cartridge filter. This is a S.S.316 Vessel fitted internally with P.P spun micron cartridge elements having absolute ratings of 1.0 micron & 0.2 microns which removes all bacterial impurities present in the water and make the water free of particulates.

RO water is like pure distilled water that is 100% water without any dissolved salts. All RO water purifier manufacturers are aware of this, so some RO water purifiers have a Cartridge called a remineralizer cartridge, filled with purified alkali essential mineral salts of Calcium and Magnesium, through which the pure RO water passes through. Thus the pure RO water dissolves some of the essential minerals from this remineralization cartridge or an alkalizer to give alkaline RO water. The alkaline RO water is good for health.

Through R.O. treated water is free from all the micro- biological impurities like Bacteria, Virus, etc. it may redevelop again in water during prolonged storage. For dis-infection of water is essential for Reverse Osmosis Application before Filling & Sealing in bottle. Hence, an online Ultra Violet is provided for disinfection of R.O. treated water before filling in pre-cleaned PET Bottles. 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. These systems consist 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.

Though R.O. System rejects all the micro – organisms like bacterial & virus and even after passing through U.V. System it may redevelop in packed bottles over a period of time. Hence, it is necessary to disinfect R.O. Product water prior to bottling filling. This is very much essential to ensure good Mineral Water Quality as per the standards. This Ozone Generator will give your water Oxygen Rich water and remove the Bacteriological growth and also provide you the Shelf Life of your Packed Bottle water unless it opens for some period of time. Also, this Ozonation of water can add some taste in to your treated water.
