5 Stage Water Filter / Purifier
5 স্টেজ ওয়াটার ফিল্টার / পিউরিফায়ার
Stages of water purification
The feed water flows through the three pre-filters intended to reduce sediments (rust, sand, silt etc.), chlorine and chlorination by-products, as well as organic matter.
The fourth stage is represented by the reverse osmosis membrane which at the molecular level purifies the water from 99.8% impurities including bacteria and viruses. The purified water is supplied to the storage tank.
The carbon post-filter is the fifth stage of the water treatment. It contains high-quality activated coconut shell carbon which improves purified water taste and odor, and adds slight sophisticated sweetish flavor.

Pressure in storage tank, atm: 0.4–0.6**1
Temperature of feed water, °C: +4…+30***
Filter weight (basic configuration), kg: 7
Temperature of environment limit, °C: +5…+40***
Water supply external connection, inches: thread, ½
* If the pressure in the water supply system is lower than indicated, the filter should be supplied with a pump. If the pressure in the water supply system is higher than indicated, it is necessary to install a pressure regulator at the inlet before the reverse osmosis filter.
** If the pressure is lower or higher than indicated, it is necessary to pump up or release the pressure.
*** If the temperature of feed water is within the range +20…+30 °C, selectiveness of the membrane insignificantly decreases, and capacity increases leading to insignificant growth of the TDS indicator. Application of the filter when the temperature of feed water exceeds +30 °C is not recommended.
