World Latest Technologies of Process for Mineral Water (Bottled Water) Production from Different Source of water Link Bore Well, Deep Well, River Water, Sea Water etc.
1) CHLORINE DOSING SYSTEM: AS PRE TREATMENT (WATER HAVING IRONCONTENTS)
Raw water may contain living micro organisms and organics which are objection Membrane as it may cause fouling to deterioriorate the performance. Even water may contain ferrous which can be oxidized to ferric oxide which settle down in storage tank. We propose 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 HDPF hypo chlorite solution preparation tank along with one number 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.
2) RAW WATER STORAGE TANK:
This is required in for storage of chlorinated water having appropriate capacity. The tank is fitted with PVC pipe work & isolation valves suitable type of level indicator.
3) RAW WATER SUPPLY PUMP:
A Horizontal Centrifugal type of pump in Stainless Steel construction 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 Pressure Scnd Filter Unit.
4) PRESSURE SAND FILTER:
Raw Water is first filtered by filter unit in series prior feeding R.O.Plant. pressure Sand Filter Unit is provided for removal of suspended matters & turbidity from raw water. PSF Unit is a SS/FRP vertical Pressure Vessel. Internally, it is fitted with bottom collecting system. A uniform grades silica quartz sand is placed on the supporting media of pebbles and gravels. This unit is fitted with SS frontal pipe work and Valve externally. During service cycle water is passed in down word 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 flow reduces. At this stage filter bed need to be backwashed.
When pressure drop across the sand bed increases beyond the specified limit (0.5 kg/cm2) or quality of filtered water detoriates, which ever is earlier. Regeneration involves backwash & rinsing of Stand Bed. 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 5 -10 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.
5) GRANULE ACTIVATED CARBON FILTER :
Natural water may contain Colour, Odour, and 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 dis-infection, it is necessary to remove the free Chlorine feeding to R.O System. Chlorine being a strong oxidizing agent, it damages membranes. Activated Carbon can remove Chlorine, Odour, & Colour while passing the water through carbon bed along with Odour & Color. This Carbon granule having larger surface area and specific property to absorb organics. ACF Unit is a FRP / SS vertical pressure vessel. Internally it is fitted with SS frontal pipe work & valve externally. A granular activated carbon is placed on the supporting media of Coarse & Fine Sand. 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 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.
6) ANTI SCALENT DOSING: The hardness salts of calcium & magnesium are likely to be precipitated if concentration exceeds its solubility limit & it may foul the membranes resulting into scaling which ultimately leads to poorly treated water quality from R.O. System. To prevent this a anti scalent dosing ( scale inhibitor ) dosing system is provided. Normally a scale in habitator chemical is dosed in feed water. Dosage rate @ 4-5 mg/liter. A HDPE chemical preparation tank with an electronics diaphragm type dosing pump is provided for this.
7) MICRON CARTRIDGE FILTER:
Micron Cartridge Filter having Series of filtration with the 10 Micron 5 Micron, 1 Micron, Cartridge. These are Cartridges should be replaced approximate 90 Days of operation. This is extra safety of your product water as it comes through the followed filtration and there are no chances for any particles to slip.
8) HIGH PRESSURE PUMP: For Reverse Osmosis Process 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 minimum operating pressure of about 6.0 kg/cm. 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.
(R.O. Pressure varies according to water quality & type of membrane)
9) REVERSE OSMOSIS 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 Skid. High pressure rating FRP / SS Pressure Vessels are fitted on the skid which houses spirally wound membrane elements in series.
In RO System feed water is divided into two streams viz Product & Reject water. Product water / 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 pressure is first feed 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 strong tank and reject is drained off.
For safe operation of system following instruments are provide on Panel
a). Feed & Reject pressure Gauge System. : To indicate respective pressure of R.O
b). Feed & Reject Flow Indicator System : To indicate respective flow of R.O.
c). T.D.S Meter water. : To measure TDS of Raw / Treated
d). High Pressure Switch : For tripping high pressure pump in case of excessive feed pressure to R.O. System.
e). Time Totaliser : For counting working hours of H.P Pump/ R.O.System.
10) PRODUCT WATER STORAGE TANK: One No. of Treated water from R.O. System is stored in a 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 next unit i.e. microncartidge filter.
11) MICRON CARTRIDGE FILTER II & III: 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 elements having absolute fitted internally with P.P spun micron cartridge elements having absolute ratings of 1.0 microns which removes all bacterial impurities present in the water and make the water free of particulates.
12) ULTRA VIOLAET STERILIZER: 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 disinfections, a online Ultra Violet Sterilizer is provided for disinfections 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 is surroundings this tubes during treatment. An electrical system is provided for production of high voltage required for U.V. Rays generation.
13) OZONE GENERATOR: Through 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 provided 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.
