S/N. | Commodity name | 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 pretreatment 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 | Security filter or pp filter, or called PP sediment filter | prevent large particles, bacteria, viruses into RO membrane, accuracy is 5µm | |
7 | High pressure pump | Provide needed working pressure for RO system, ensure production capacity of pure water. | CNP pump, Grundfos optional |
8 | 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 |
Reverse Osmosis or (RO) can be described as a procedure whereby pure water and contaminants is divided via a semi-permeable membrane(s) with very fine pores. This method is a necessary technique employed in the majority of water purification systems. Reverse Osmosis is considered to be a highly effective approach to eliminating water impurities, such as Toxic Heavy Metals i.e. Lead and Radium, Mercury, Chlorinated Pesticides, organic matters, Turbidity & Dissolved Solids, bacteria, virus.
RO system is widely used in water treatment, purification for tap water, well water, underground water, borehole salty water, brackish water and seawater, pure water and ultra-pure water production. Application area such as, food processing, bottled drinking water, home use drinking water, power stations, electronic industries, cosmetics production, pharmaceuticals manufactories, and medical treatment(such as hemodialysis). It is a key equipment for pure water plant and ultrapure water equipment.
