Household water purifiers will produce four times more wastewater during production. This is because the main function of the RO membrane is to remove salt from the water. Since the salt accumulates on the surface of the membrane, a portion of it needs to be used. The purified water that has been filtered by 5 micron PP filter element, 1 micron PP filter element (granular activated carbon), and compressed activated carbon will wash away and take away the salt on the membrane surface, so the drained water is purified water and is much cleaner than the original water. , but the salt content has increased by 20% compared with the original water. But you can’t drink it without professionals, and the waste water can be recycled. Definitely better than raw water. You can take a bottle each of raw water and drained water and put it in the sun for an hour, and you will know by looking at the precipitation of the water quality.
