S/N | Commodity name | Description/Application | Remark |
1 | Raw water tank | Store water, buffering pressure, overcome instability of supplying water by pipe, ensure to supply water stably and continuously for whole system | Customer provide for themselves, because big size will result in expensive freight. |
2 | Raw water pump or called booster pump | Provide needed pressure for every pre-treatment filter | We can provide CNP pumps or Grundfos pumps |
3 | Mechanical filter or called quartz sand filter or sand filter | We use fiber glass or stainless steel vessel as housing, fill quarts sand, it can filter big particles impurities, suspended substances, colloids etc. | |
4 | Activated carbon filter | We use fiber glass or stainless steel vessel as housing, fill activated carbon, remove color, odor, residual chlorine and organics substances. | |
5 | Water softener, demineralizer, or called Na+ exchanger | Adopt cation resin to soften water, cation resin will absorb Ca2+, Mg2+(main elements for composing scale), reduce hardness of raw water, System can make resin intelligently regenerate, recycling | |
6 | Antiscalant dosing system or PH regulating system | Dosing antiscalant into feed water, prevent the ro membranes from blocking, prolong the lifetime of RO membranes. Regulating PH to suitable range. | |
7 | Security filter or pp filter, or called PP sediment filter | prevent large particles, bacteria, viruses into RO membrane, accuracy is 5µm | Stainless steel housing or ABS housing or FRP housing |
8 | High pressure pump | Provide needed working pressure for RO system, ensure production capacity of pure water. | CNP pump, Grundfos optional |
9 | RO(reverse osmosis) system | Can remove particles, colloids, organic impurities, heavy metal ions, bacteria, virus, heat source etc. harmful substances and 99% dissolved salts. | RO membranes USA Filmtec Dow |
10 | CIP cleaning system | Cleaning RO membranes with chemicals | |
11 | Sterilizer device | UV sterilizer or ozone generator |
