| Each part function of the drinking water purification system | |||
| 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 (feed water pump) | Provide needed pressure for every pretreatment filter | We can provide CNP 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. | We use China brand or WAVE CYBER brand |
| 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. | We use China brand or WAVE CYBER brand |
| 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 | We use China brand or WAVE CYBER brand |
| 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. | Italy SEKO dosing pump or German Prominent |
| 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 PVC housing |
| 8 | High pressure pump | Provide needed working pressure for RO system, ensure production capacity of pure water. | CN pump |
| 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 | CNP pumps |
| 11 | Sterilizing device | UV sterilizer or ozone generator | BNP ozone |

High-Efficiency RO System
Advanced reverse osmosis technology with corrosion-resistant components ensures stable desalination performance, even in high-TDS environments (up to 45,000 ppm).
Durable & Marine-Grade Materials
Components built from SS316, duplex stainless steel, and anti-corrosion coated frames for extended operation in harsh marine conditions.
Containerized or Skid-Mounted Options
Choose from compact skid-mounted units or fully containerized plug-and-play systems (20ft or 40ft), ideal for remote sites or fast deployment.
Pre-Treatment Included
Multi-media filtration, anti-scalant dosing, and cartridge filtration ensure RO membranes operate efficiently and last longer.
Optional Solar Power Integration
For off-grid use, we offer solar-powered versions for eco-friendly water production.
The solar powered is optional , If your location does not have enough sunlight, you can also choose not to configure the solar container RO plant
