Imagine you’re hosting a barbecue, and you’ve got a bouncer at the door. The bouncer’s job is to only let the pure, well-behaved H2O molecules into your backyard. But the bouncer is a real tough guy. He’s not just checking IDs; he’s body-slamming every mineral, chemical, and stray particle out of the way. The result? A lot of shoving, a few spills, and a huge mess on the sidewalk. That spill—that’s your waste water.
Your RO membrane is that bouncer. It physically blocks contaminants by squeezing water through microscopic pores. To keep those pores clean and prevent them from getting clogged with gunk, the system constantly flushes the leftover salty, dirty water away. Think of it as the bouncer spraying a hose at the crowd. It’s not polite, but it keeps the party going.
