Raw water may contain living micro-organisms and organics which are objectionable to R.O. Membrane as it may cause fouling to deteriorate the performance. Even water may contains ferrous which can be oxidized to ferric oxide which is settle down in storage tank. We have offered a Hypo chlorite dosing system for this purpose. About 3-4 ppm of sodium hypo chlorite solution is dosed in raw water storage tank. This reacts with water to form a hypo chlorite acids which acts as disinfecting agent.

For this purpose one no. of HDPE hypo chlorite solution preparation tank along with One nos. of dosing pumps are provided. Required suction / discharge pipe work in pvc construction is provided with isolation valves. Dosage rate is adjusted as per the actual requirement, which may very on case to case basis


One No. of Raw water is required in for storage of chlorinated water having appropriate capacity. The tank is fitted with PVC pipe work & isolation valves and suitable type of level indicator.


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 s.s construction with isolation valves are also provided up to PSF Unit.


Raw Water is first filtered by filtration unit in series prior feeding Plant. pressure Sand Filter Unit is provided for removal of suspended matters & turbidity from raw water. PSF 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 backwashed.

When pressure drop across the sand bed increases beyond the specified limit (0.5 kg/cm^2) or quality of filtered water determinates, which ever 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. 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.


Natural water may contain Colour, 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, & 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 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/cm^2) or quality of filter water deteriorates, whichever is earlier the unit is isolated for regeneration. 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. Particularly iodine value is most important for this application. Generally carbon is replaced once in a year.


The Chlorinated water may oxidize the membrane and to avoid the same precautionary we have provided Sodium MetaBiSulphite dosing system Dosage rate is 4-5 mg/liter. A HDPE chemical preparation tank with an electronics diaphragm type dosing pump is provided for this.


The hardness salts of calcium & magnesium are likely to be precipitated if concentration exceeds its solubility limit & it may faults the membranes resulting into scaling which ultimately leads to poor treated water quality from R.O.System. To prevent this a anti Scalent dosing (scale inhibitor) dosing system is provided.

Normally a scale inhabitator like Perma care 191 or equivalent chemical is dosed in feed water. Dosage rate is 4-5 mg/liter. A HDPE chemical preparation tank with an electronics diaphragm type dosing pump is provided for this.


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/cm^2 . 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 recirculation valves are provided for safer operation of 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 M.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.

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 Totaliser for counting working hours of H.P Pump/ R.O.System.


One No. of Treated water from R.O. System is stored in a 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. One no. of transfer pump is provided in S.S. material of construction to feed the water in 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.


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, a online Ultra Violet Steriliser 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 micro organisms. This systems 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 systems 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 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 open for some period of time. Also this Ozonation of water can add some taste in to your treated water.
