Questions on Countertop Reverse Osmosis Water Dispenser

[Billy the Mountain]

from my understanding it resuses the waste water to extract as much as possable but in turn does not give zero ppm . you end up with around 50 ppm in the usable water but again it could just be marketing lies

It's possible, but I'm certain there doesn't exist an RO membrane with better than 1:1 ratio of treated to rejected water. The vast majority of RO membranes available are 1:2 or 1:3.

Either they're lying or they've developed a RO membrane 3x more efficient than anything currently available.

I'll let you decide which is more likely.

im sorry i had to make a bad joke i was rather stoned at the time

I understand. No problem.

A 1:1 membrane ? Sounds not plausible...
Any links ? Would love to put one in my RO system

One example:

Reverse Osmosis Water Filtration System | 1:1 Drain Ratio - High Recovery, Low Waste Unit 50% California Edition

Amazon.com

It may be a California regulation for water conservation??

Looks decent, thank you very much.

stuff it im a buy one on my next pay in a month if funds still allow for it lol . i will come back and post about it if i do buy one . idk must be some sort of witchcraft going on if its a true 3 to 1 what im guessing its not really but i will find out haha

You guys realize water is never actually wasted right? Just because a gallon of water goes down the drain doesn’t mean it gone forever..

When do you expect it to return?

If you get a cheaper dual membrane unit and run it in series instead of parallel, you will save water without affecting output EC by much.

I think my 5-stage system's waste-water ratio is around 1:1.5 running this way. Luckily my water pressure is sitting around the ideal 65psi per the manual, so I'm just assuming it's true. Haven't tested it yet but while the system is flowing, the output of both lines seems to be almost identical. So, I'd say it's pretty close to 1:1.5

It's the filter.... you can use zero pitcher to filter. I just use tap water now. I use to let water stand and do water rotations. Not necessary, not growing trees or orchards.
