How Reverse Osmosis System is different from a resin based Softener process? Under no circumstances can you drink resin-softened water. Softener converts hardness which is in the form of Calcium & Magnesium into Sodium. There is no reduction in the total salt content of the water. Softened is good for washing clothes, preventing scaling in your geyser and washing machine. But under no circumstances it can be used for drinking or cooking.
What is the difference between the Ultra Violet & Reverse Osmosis Water purifier? Ultra Violet water purifier only inactivates microbes, that too they cannot remove protozoan cysts of amoebae and Guardia. Also it does not reduce salt content of water while reverse osmosis water purifiers can virtually make any water potable. Reverse osmosis water purifier gives you sweet, pure, and safe drinking water eliminating the harmful chemicals, microbes and excess salts & hardness from the water.
When Should The Membrane Be Changed? One indication is a gradual reduction in water production caused by a layering of minerals and salts on the membrane surface. Another is a gradual deterioration in the quality of water being produced. You may notice a different taste or more white scum on the inside of a pan of water you are boiling. This might mean the RO membrane is disintegrating and requires replacement.
What Is Important Of Water Pressure To A RO System? It is the pressure of water that forces water through the membrane for purification and flushes the rejected solids away. Low water pressure will result in reduced production and premature fouling of the membrane. The ideal pressure for operating an RO system is 60 PSI. Pressure below 40 PSI is generally considered insufficient, and should be boosted using a pressure booster pump.
How Can A Line Be Run From The RO Unit? Approximately 10-15 feet with ¼" POLY tubing. Tubing that runs from the RO system for the icemaker & other uses should always be POLY tubing, not copper.
Isn't Water Wasted By RO System? There is a significant percentage of water from the system that goes to the drain. This water is carrying away the impurities. These particles are too small to be caught by the filters. Reverse osmosis has an automatic shut-off valve that shuts off the flow of water to the drain when the holding tank is full. This valve stops the RO system from continuously running water down the drain, thus conserving water as the RO System works according to usage.
Can This Water Be Saved And Used? Yes, most waste water today is recycled for golf courses and artificial lakes. The drain water is slightly higher in TDS concentration than the incoming water, but as RO does not added anything to the water, it can be used to water your lawn or garden.
