Hi all,
Thanks for your help on my question about RO and chloramines. I have questions about what configurations are sensible to reduce waste water.
I see two ways to reduce the amount of wastewater produced by the RO unit:

Thanks for your help on my question about RO and chloramines. I have questions about what configurations are sensible to reduce waste water.
I see two ways to reduce the amount of wastewater produced by the RO unit:
- Using a booster pump. This is purported to reduce the waste ratio to approach 1:1.
- Using two membranes in series. This is purported to reduce the waste roughly by half.
- If the water pressure is sufficiently high (> 60psi) is there still a benefit to using the booster pump? Is added pressure the only thing that reduces waste? And if so, what pressure is needed to approach a 1:1 ratio?
- If I connect two membranes in series and there is sufficient water pressure (> 60psi) would a booster pump reduce the waste further, or are there diminishing returns to combining these two methods?
Cheers
