... is time to replace if flow rate is too less or membrane is cloged..
Could i use it if my water Total Dissolved Solids is over 1000 ppm or well water?.
Yes, you can use it. even TDS reach 2000 ppm. but you should replace membrane every 12 months or more frequently.1000ppm is our suggestion..
Can this be used for brackish water(5000ppm) or ocean water with high salinity(35000ppm)?.
No. it is just designed for residential tap water use. if you need Ro membrane for brackish water or ocean water and industrial use, Geekpure can provide too, please send email to us..
Just 1pc membrane. membrane housing, wrench and flow restrictor need to be bought separated..
2. If you have chlorinated water, we recommend you use a Carbon/Sediment Pre-Filter. The residual chlorine in municipal or city water will destroy the membrane. if hardness is too high, we recommend you install water softener before Ro unit..
