- 5. SALIENT FEATURES OF KENT GUARD DOUBLE PURIFICATION BY RO+UV PROCESSES. IN-BUILT TDS CONTROLLER THAT ALLOWS ADJUSTEMENT OF TDS LEVEL OF PURIFIED WATER. SUITABLE FOR PURIFICATION OF BRAKISH/TAP WATER/MUNICIPAL CORPORATION WATER. WALL MOUNTED DESIGN; BEST SUITED FOR INDIAN HOMES AND OFFICES. FULLY AUTOMATIC OPERATION, COMPUTERISED. FILTER CHANGE ALARM. U.V FAIL ALARM. Kent Instruction Hand 5
- 6. TECNOLOGY USED 6 1.REVERSE OSMOSIS Water pressure is applied to the concentrated side, forces the process of osmosis into reverse. It is also known as hyper filtration. Under enough pressure, pure water is “squeezed” through the membrane of pore size 0.0001µm from concentrated salt side to diluted side. Kent Instruction Hand
- 7. Contd…. 7 UV PROCESS UV rays, has shorter wave length (higher energy) than the visible light, penetrate into the micro- organisms, are absorbed by the DNA of the pathogen in the water. The DNA is altered in such a way that pathogens cannot reproduce itself. Kent Instruction Hand

- 10. Contd.. 10 Water production and distribution cost @Rs32/kl (As per PHED GoR) For One Yr 60x365x32 = Rs700/Yr 1000 Maintenance Charges UV Bulb @Rs 300/Year (amazon.in) Booster Pump @Rs 1500/5Year or Rs300/Yr Membrane and other cartage costs @4000/Yr Annual Service Charge @ 3500/Yr Total maintenance charge @Rs/Yr is Rs8100/Yr
- 11. 11 If We take depreciation @10% i.e Rs1490 /Yr Chargers of RO Purifier/Yr is Rs1490+Rs153+Rs700+Rs8100=Rs10443 Total Water Produced 60x365=21900lt Cost per lt is 10443/21990= 47 paisa per lt Contd..
- 12. Quality wise 12 It produces almost distilled water. It removes all pathogens, viruses, cysts and minerals( mono valent ions too). IT IS DESEASE FREE GOOD DRINKING WATER
- 13. DEMERITS OF KENT R.O. 13 It requires electricity to operate, useless in areas where power is erratic. High capital cost & maintenance cost. Water rejection is high,40-70%. & Reject is highly salty. It bypass some water before RO membrane to control the TDS level. This is useless if water is contaminated with harmful minerals like Arsanic, Lead, Hg or Cadmium. Membrane removes almost all pathogens/viruses, no need of UV disinfection. If we consume this water for long time and then we use non RO water , chances of getting ill. It does not gives residual disinfectant effect.
- 14. 14 1. The ground water normally does not contains pathogens and viruses, hence there is no need of UV disinfection unit. 2. TDS controller can not maintain the desired level of useful minerals(Ca & Mg). If these are added externally like in Bisllary Brand bottled water, adds extra cost. 3. It is not economical and wise activity to purify surface water. It can not afford by common peoples. 4. It can be used only where surface water source is available at long distance and ground water is not as per standards. 5. It is advisable to filter small quantity of water with arrangement of reject in the low level use.
