What is RO plant and why do we use it?
RO water purifier systems are the most used purification system used in India. RO means Reverse osmosis i.e. solvents (like TDS, metallic ions and unwanted materials) flow out from higher concentration to lower concentration in water through a semi permeable membrane when pressure is applied. This water is now free from pollutants but not from pathogens, for that UV(Ultraviolet) rays are used.
Clean drinking water is basic requirement for everyone and anyone. These days we buy packaged water while travelling or when thirsty, we never think of going to a nearby municipality tap and drink water from there.
Why do we do that?
Simple, that water may be containing pollutant, disease causing pathogens or simply not good in taste.Thus, its demand is only increasing day by day. Commercial RO systems demand has increased as pure drinking water is basic need of any place. Commercial places like malls , offices, shopping complex, clubs , hotels, schools , colleges all require clean water which is free from all pollutants. Also , wastewater is reclaimed from these places to move towards sustainability goals of United Nations.This wastewater is reclaimed through a long process of filtration and disinfection.
Why 500 Lph and not lesser?
The per capita demand of water in commercial places varies from 45L/capita/day to 450 L/capita/day. This shows variation of demand which is highest in hospitals and lowest in factories. The average water demand is 135 l/capita/day. Thus water requirement is high and we need high water flow to fulfil the needs of the place.
Certification used in RO systems
- 1. ISI certificate
- 2. NSW certificate for membrane
Comparative cost analysis of 500 Lph Commercial RO plants in India
The general costing of a 500 Lph commercial plant varies around 1,00,000/- to 2,00,000/- rupees which is again influenced by the type of membrane, type of pre- filter material and type of disinfectant used. The price varies from one company to another on the basis of certifications and brand value.
