Following Processes are necessary to treat water to desired level.Get an Instant Quote
Raw water may contain living microorganisms and organics, which are objectionable to the Membrane as it may cause fouling and further oxidation to deteriorate the performance of the filters and the RO membrane. This process can be made manually or can be automated depending upon requirement. For automation one no. HDPE hypochlorite solution preparation tank along with one nos. of electronic diaphragm dosing pump is provided. Dosage rate is adjusted as per the actual requirement, which may vary on a case to case basis.
The chlorinated water is first pumped to this section which is called the Pressure Sand Filter unit which is in series prior feeding to the R.O.Plant. A Pump is used for the purpose to generate the required flow rate and pressure. Pressure Sand Filter Unit is provided for removal of suspended matters & turbidity from raw water. Lesser the velocity higher is the effective filtration, Sand filters used by reputed brands like Bailley, Aquafina, Kinley etc operate sand filters at lower velocity ensuring higher filtration efficiency.
Raw water contains Colour, Odour, Chlorine & Organics in different proportions, which is objectionable for potable application, and hence, it is a necessity to remove the same from water. If raw water is chlorinated for dis-infection, it is necessary to remove the free Chlorine present in the water before it is being fed to the R.O System. Chlorine being a strong oxidizing agent can damage the R.O. Membranes. Activated Carbon can remove the free Chlorine, Odour & Colour from the water after it is passed through the carbon bed. These Carbon granules have larger surface area and specific properties to absorb organics.
The hardness of water mainly depends upon the following two constitutions of the salts of calcium & magnesium which are likely to be precipitated if concentration exceeds its solubility limit & it may result in flaw to the R.O. membranes resulting in scaling which ultimately leads to poor treated water quality from R.O. System. To prevent this scaling effect a anti Scalene dosing (scale inhibitor) dosing system is provided. Normally a scale inhibitor like Hypersperse MDC150, Perma care 191 / Flocon 260 or equivalent chemical is dosed in feed water.
Pre Micron Filters are Micron Cartridge Filter having Series of filtration with the combination of any two of the 20-Micron, 10 Micron, 5 Micron Filters. Depending Upon quality of water. Nominal & Absolute Micron Cartridge. This is a Consumable Cartridge and should replace it after Days of operation normally around one to two months.This for Extra Safety of the Product water as it comes through the followed filtration and there are some chances to slippages for any particles which can be stopped through the Cartridge this micron cartridge filter will also take care of microbiological growth up to 5 micron. These filters are usually housed in PP / PVC or SS housing.
In the Reverse Osmosis System the membrane will reject around 98 – 99% of total dissolved solids by the principle of `Osmosis’. This system consists of a R.O. Module assembly mounted on MS / SS Skid. High pressure rating FRP / SS Pressure Vessel is fitted on the skid which houses spirally wound membrane elements in series. The membrane is made up of TFC (Thin Film Composite). The number of membranes will depend upon the capacity of the output required. Normally used membranes are 4” x 40” (4040) membranes with derived output of approx. 250Litres / Hour and 8” x 40” (8040) membranes with derived output of approx. 1000 Litres / Hr.
This reject water can be further used for flushing, washing and gardening activities in the plant. The rejected water can also be dumped into a sump in the ground where the water can percolate in the ground and recharge the groundwater table.
Here the R O treated water (the product) is collected in a Collection tank which is generally 50 to 100 % of the RO output capacity. Water from the RO generally does not have enough pressure to pass through further Filtration elements and hence is thereby required to be re-pressurized so that it can pass forward through the further process.
This is also an optional process and is required only if the RO treated water is not maintaining its pH value in the desired limits. This process is automated. For automation two no. HDPE solution preparation tank along with respective two nos. of electronic diaphragm dosing pump is provided. One tank contains Acid chemical in dilute form and one tank contains Alkali chemical in dilute form, Dosage rate is adjusted as per the actual requirement, which may vary on a case to case basis. The kind of chemical to be used is referred to by the plant designer. For Mineral dosing also similar kind of technique is used and normally Magnesium Sulphate and Potassium Bicarbonate is used, Dosage rate is adjusted as per the actual requirement, which may very on case to case basis.
Though R.O. treated water is free from all the microbiological impurities like Bacteria, Virus, etc. it may redevelop again in water during prolonged storage. For disinfection of water it is essential for the water to be treated with U V before Storage, Filling & Sealing bottles. 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 U.V. System, which consists of U.V. Tubes, which radiate high intensity UltraViolet Rays, which in turn kills the microorganisms. This system consists of an SS finished surface housing with Ultraviolet Lamps fitted in it. The water to be treated is surrounding these tubes during treatment. An electrical system is provided for production of high voltage required for UV Ray’s generation.
During storage & due to atmospheric or any other factor contamination may take place in R O treated water and also after UV sterilization dead bacteria are present in water. Hence, the water is once again passed through a set of micron cartridge filters. These are S.S.316 Vessels fitted internally with P.P spun micron cartridge elements having absolute ratings of either 0.45 micron or 0.2 microns or combination of both depending upon requirement, each which removes all bacterial impurities present in the water and make the water free of particulates.
Though R.O. Systems along with micron filters and UV sterilizer reject all the micro – organisms like bacteria & virus there always remains a chance that they may redevelop in packed bottles over a period of time. Ozone being a strong oxidizer and disinfectant acts to disinfect the Product water prior to filling. This is very much essential to ensure good Packaged Drinking Water Quality as per the standards. This Ozone Generator will actually help in providing enhanced Shelf Life to the water in packed condition over a period of time. Also this process can add some taste and rectify the pH in the product water. The ozone generator provided herein uses atmospheric oxygen to generate Ozone using corona discharge technology. Oxygen concentrators are used in combination with the generators for higher concentration ratio.
