Understanding dual RO membrane diagram: get a clear picture of the double filtration process.

Okay, so, I’ve been messing around with this whole water filtration thing lately, specifically trying to get my head around how a dual RO membrane setup works. Let me tell you, it’s been a bit of a journey, but I think I’ve finally cracked it.

First off, I started where anyone would – just staring at the RO membranes themselves. They are the main part, right? They are kind of these cylinder-looking things that are supposed to do all the heavy lifting, taking out all the bad stuff from the water, like metals and salts and junk.

I decided to set up a basic system first, just to see it in action. I hooked up one RO membrane to my water supply, with a little help from some basic plumbing I picked up at the hardware store. This was like my test run, you know? I connected some tubing, made sure I had a faucet for the filtered water, and then turned it on.

The water started flowing, and I could see the membrane doing its thing. After some time, I started getting clean water out the other end. It was really satisfying to see it actually work!

Emboldened by my initial success, I decided it’s time to go dual. I mean, if one is good, two’s gotta be better, right? This is where it got a bit more complicated. I added a second RO membrane, connecting it in series after the first one. Basically, the filtered water from the first membrane went straight into the second one for a second round of cleaning.

• First step: Get a second RO membrane and a few extra bits of tubing and connectors.
• Second step: Disconnect the output from the first membrane.
• Third step: Connect the output of the first membrane to the input of the second one.
• Fourth step: Connect the output of the second membrane to my clean water faucet.

Fired it up again, and waited. I’ll admit, I was a little nervous. Would it even work? Would I just end up with a watery mess all over my floor? But, lo and behold, it worked like a charm!

The water that came out after going through both membranes was, no joke, noticeably clearer and tasted better. I even did a little taste test with some water from just the single membrane setup, and the difference was real.

Cleaning

Then it hit me: these things need cleaning. I read somewhere online that you can use chlorine bleach, or even something called hydrochloric acid. Apparently, you just soak them for a while, and that’s it. I haven’t done it yet, but it’s on my to-do list.

So, yeah, that’s my little adventure with dual RO membrane systems. It was a bit of trial and error, and a whole lot of learning, but totally worth it. Now I’ve got this sweet setup that gives me super clean water, and I did it all myself. Pretty proud of that, not gonna lie. Hope this was helpful. See ya!
