100GPD RO/DI UNIT

[marinelife]

I have a 100gpd Baracuda RO/DI 4 stage unit. I set it up and the unit is giving me more waste water than good water. Is this common to have more waste water than good water coming out of the unit.

 

[MarkS]

Yup. General rule of thumb is 4 gallons of waste water for each gallon of filtered water.

It's standard. Didn't the instructions say as much?

I did not get any paper work with it. I guess I will be setting up a shut of, so i can turn of the input water so it does not run all the time.

If they've got a website, check it out as well. I plumbed in a pressure and temperature guage to my water supply to my ro/di so I could check the performance of my membranes and cartridges every now and then.

It is made by AquaFX, I have checked there website and going to call them tomorrow, I just wanted a check today, I know others have there products. Just hated to wait until tomorrow

They build a nice product, you may want to look into a permeate pump.

A Permeate Pump increases net pressure across the RO membrane by isolating the membrane pressure from the pressure in the product water tank, thereby reducing the permeate back pressure to less than 3 psi. Using a permeate pump with an automatic shut-off valve greatly increases water purity stored in the tank, eliminating TDS (Total Dissolved Solids) creep. The pump requires no electricity and is powered by energy from brine normally lost to drain. The use of permeate pump increases membrane life and pre-filter life, reduces waste water by 80%, and fills up the tank 2 times faster than conventional units.
