Page 3: Iintroduction To Reverse Osmosis
To carry the rejected material away from the membrane surface, the feed side of the R.O. membrane is continually flushed with an excess flow, usually two to five times the product flow. T his avoids clogging of the membrane surface and reduces the tendency toward scale formation. Water Tec Int’l. Inc. Version 02A... -

100 gallons of feed water into the membrane and you produce 60 gallons of product water and 40 gallons of reject water, this is known as 60% recovery. PERCENT REJECTION The amount of salts or chemicals rejected by the R.O. membranes. Water Tec Int’l. Inc. Version 02A... - Page 5 When the feed water is entering at 500 PPM, the product water would be from 25-50 PPM (90-95% rejection of dissolved minerals). Usually a conductivity meter or “total dissolved solids” meter is used to measure the mineral content of the product water. Water Tec Int’l. Inc. Version 02A...

Page 6: Purified Water Storage And Delivery
The pumps must never be allowed to run dry, since this will rapidly deteriorate the shaft seal and cause the seal to leak. To prevent this the storage tank should be fitted with a low level switch, which shuts down the distribution pump if the water level in the tank gets dangerously low. Water Tec Int’l. Inc. Version 02A... -

All X frame units include a dual switch to read the pre-membrane TDS and the post-membrane TDS. Water Tec Int’l. Inc. Version 02A...
- Page 9 This is a normally closed electric ball valve. This valve is located on the feed side of the pressure pump. Its purpose is to shut off the feed supply when the unit is in the non-operating mode. If electric power should fail this valve will not close. Water Tec Int’l. Inc. Version 02A...

After about 30 minutes the incoming and product water should be tested with a TDS Meter. There should be no less than a 90% rejection. If the rejection is lower than 90% double check the membrane installation and Water Tec Int’l. Inc. Version 02A... -

Fouling and scaling on the membrane is one of the main reasons a water softener is recommended before an R.O. It is always best to use a twin alternating unit in order to ensure continuous soft water. Water Tec Int’l. Inc. Version 02A...
