Why do Seres RO water purifiers produce wastewater?

RO reverse osmosis is a technology that has been extended from the industrial and chemical fields to the household field with the wider use of semi-permeable membranes. RO reverse osmosis water purifier that produces wastewater. The main difference between the two is that the latter has the ability to purify water further through the application of RO reverse osmosis technology, and has the ability to reduce the content of inorganic salts soluble in water and produce softened water.

But, do we know why the RO water purifiers produced watewater? 

This is related to the fact that the semi-permeable membrane intercepts the salt on the high-concentration side. As mentioned earlier, the salt that cannot pass through the semi-permeable membrane will be deposited on the high-concentration side. At this time, in order to prolong its service life, a self-cleaning method is required. On the surface of the high concentration side of the semipermeable membrane, the carrier of this cleaning method is naturally the water that exists in the water purifier all the time. When the user opens the faucet of the water purifier, the purification process and the flowing water The cleaning process of flushing the surface of the semipermeable membrane is carried out at the same time, and the accumulated salt is thus discharged with a part of the water as waste water. Although these waters with high salt content are not drinkable, they have also undergone the basic purification of various filter elements before the semi-permeable membrane, and there are many scenarios that can be used, so it is not a waste of water resources. 

Seres water purifier has more than 10 years in the field of water treatment in China. We have always keep our attention to the technology upgrade and water quality improve in the past years.
