What happens to all the organic and inorganic impurities removed by Coway R/O Water System?

They are automatically rinsed from the membrane surface and washed down the drain. Unlike filters that trap impurities, the membrane used in Coway R/O Water System is self-cleaning. As water flows across the membrane, it becomes divided into two streams. The production stream is the purified water that is forced through the membrane by diffusion. The impurities are left behind. The concentrate stream serves as a rinse that carries those impurities off the membrane surface and into a drain. As a result, accumulation of impurities on the membrane is slow, keeping it clean and effective over time.
