Reverse osmosis Newbie help

[draxcel]

I recently got my First Ro system.It Is an Aquarium System with a 75gpd rating,It has 3 stages.I used It with my main idraulic pump turned off because It wastes a lot of electricity in the Bill,and It Is running so slow,drop by drop,producin a lot of waste water.So I bought a booster pump because I noticed when using It with the main pump activated the water pressure was very strong and It gave me like 1:2-,1:3 waste water to Osmosis water.Was It a good Idea to buy the 75gpd booster pump?Will It run the osmosis system like the main pump of my house?

I Need It to produce 12 liters at day for my Coco waterings.

90% of the people out there that run a RO or RO/DI filter system have a booster pump. Takes energy to RO filter water and produces a lot of waste water. It's been this way forever and nothing will change it. Also production will go down as the filters do there job and start plugging up. There should be input pressure and flow curve info for your unit.

I have a tankless ro unit 400gpd that has a booster pump. A lot of city water systems do not have enough pressure for a reverse osmosis system to work properly so most of the time a booster pump is needed if not all of the time. They do have units out that produce less waste water however if that becomes an issue. Mine is a 2:1 but some I’ve seen go as high as 4:1 compared to the older styles which are 1:3. For what it’s worth.

My 100gpd is designed to operate above 50 psi water pressure and my well pump fills my system to 35psi so have a booster pump and 2 gal tank on mine and it does the trick.... the higher pressure is needed to force the water through the RO membrane
