Basic Accessories in a WD- Mineral Water Treatment Plant

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

For this purpose, one no. of HDPE hypochlorite solution preparation tank along with one no. 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 vary on case to case basis

One Nos. of Raw water is required in for storage of chlorinated water having the 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 to feeding R.O.Plant. Pressure Sand Filter Unit is provided for removal of suspended matters & turbidity from raw water. PSF Unit is an SS vertical Pressure Vessel. Internally, it is fitted with the bottom collecting system. 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 the downward direction through sand bed, thus entrapping suspended matter & turbid particles. Over a period of time, the sand bed gets choked due to suspended matters resulting higher pressure drop and lesser floe. At this stage, the filter bed needs to be backwashed.

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

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. An HDPE chemical preparation tank with an electronics diaphragm type dosing pump is provided for this.

Natural water may contain Colour, Odour, Chlorine& Organics in different proportion, which is undesirable for portable application, and hence, it is necessary to remove the same from the 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. These Carbon granules having the larger surface area and specific property to absorb organics. ACF Unit is an FRP vertical pressure vessel. Internally it is fitted with a strainer on the bottom collecting system. The unit is fitted with SS frontal pipe work & MPV externally. Granular activated carbon is charged on the supporting media of Coarse & Fine Silex. During service, cycle water is passed in the downward direction through Carbon Bed, which removes Chlorine & Odour from the water.

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.

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. The high-pressure pump is fitted with S.S. discharge pipework with necessary control valves. Necessary instruments like a High-Pressure Switch, Pressure Gauge, and recirculation valves are provided for safer operation of the system.

Reverse Osmosis System rejects 97 - 99% of total dissolved solids by the principle of Osmosis. This system consists of an 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 the first Pressure Vessel treated water is collected in the center core tube. Treated water from each membrane is collected jointly in a common product water storage tank and reject is drained.

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.

Pump in Stainless Steel construction has been provided for supplying water to Mineral Adding System.

R.O.Product water has very less TDS value which is not good in Taste. The Water gets bitter and to enhance the taste GIECL providing the Mineral Adding system or Blending system The Stirrer will mix the physical mineral into the Mixing tank and Dosing pump will dose the Mineral to R.O.Product water before Ozonation with TDS Controller. TDS adjustment can be done with Blending system by adding Filtered water after ACF through the proper treatment. Such Blending system is very easy in Operation and it will naturally balance the TDS into the R.O.Product water

After the Mineral Adding water will pass through the 1 & 0.2 Micron Absolute Micron cartridge filter which will take care for fine micron impurities. The Sanitary type housing and Filter will assure the High Quality Treated Water before Ozonation. It will also take care for some part of bacteria and virus. Complete in S.S. - 316 materials with PP Pleated cartridge.

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 disinfection of water is essential for Reverse Osmosis Application before Filling & Sealing in the bottle. Hence, an online Ultra Violet Sterilizer is provided for disinfection of R.O. treated water before filling in pre-cleaned PET Bottles. The water to be disinfected is passed through the 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 an 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 the production of high voltage required for U.V. Rays generation.

Though R.O. System rejects all the microorganisms 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 open for some period of time. Also, this Ozonation of water can add some taste to your treated water.
