System is pre-treatment kit with 5 mico m and 1 micro m filter followed by 3 stage pre-treatment cartridge consisting of activated carbon,
anti scaling agents and 0.5 mico m depth filter to protect down stream cartridge.
Suitable pre-treatment unit for removing hardness, iron, manganese, organics and coarse particles so as to ensure output water quality as
specified below Motor and booster pump for feed pressure.
R O grade water system
Prefilter with anti-scaling and activated carbon reverse osmosis if required for the quoted model. The reverse osmosis module is made up of
thin film composite polyamide RO membrane with rejection rate of 94-99%.
Conductivity cell after RO membrane to check health of RO membrane.
Feed water handling of conductivity up to 2000 microns/cm.
Water is treated with Single wavelength UV (254 nm) in Type 2 RO stage system and Double Wavelength UV (254/185 nm) in Type 1 system. Life of UV is more than 2 years.
TYPE 2 RO Stage Water Quality:
1 Flow rate: 10-15 L/hr
