FAQ
1. Q: Which machine should I choose?
A: It depends on your raw water quality and your requirements for permeate water.
Usually there are three parts: pretreatment, RO machine, and post treatment. Pretreatment could be UF(ultra filtration) system,anti-scale dosing system, flocculant dosing system, disinfectant dosing system, water softener, sand filter, carbon filter,security filter etc. Post treatment could be UV sterilizer, Ozonizer, ClO2 sterilizer, etc. And maybe you need an EDI system. We will choose proper process according to your raw water quality and permeate water purpose.
2. Q: What’s your machine material?
A: For pretreatment tanks, we usually use FRP or S.S. The RO frame could be S.S, carbon steel.For pipes, it is usually S.S and UPVC. We can choose material according to your special requirements.
3. Q: What’s the control method?
A: For pretreatment, you can choose manual or automatic; for the whole system, we use relay, PLC or man-machine interface remote controld
