The Commercial RO Water Purifier, manufactured by Zhangjiagang King Machine Co., Ltd., is a reverse-osmosis water treatment system designed for drinking water production and industrial process water supply. The system integrates multi-stage pretreatment, RO membrane separation, UV sterilization, and ozone disinfection in a skid-mounted configuration. Output capacity ranges from 1,000L/h (KM-1) to 20,000L/h (KM-20), covering small community water stations to large-scale water factories. RO membranes are sourced from Hydranautics (USA), and main structural components are fabricated from stainless steel 304, with the ozone mixing tower using SUS 316 for enhanced corrosion resistance. The system carries CE certification and is produced at an annual capacity of 1,000 units.
The system follows an 11-stage treatment sequence, with equipment extracted from the process flow diagram:

1 | Water pump |
2 | Silica sand filter |
3 | Active carbon filter |
4 | Sodium ion exchanger |
5 | Precision filter |
6 | Reverse osmosis |
7 | RO buffer tank |
8 | UV sterilizer |
9 | Ozone mixing tower |
10 | Ozone generator |
11 | Water tank |
The silica sand filter removes particles larger than 20μm, including sediment, rust, and suspended solids, reducing inlet water turbidity. The active carbon filter adsorbs organic compounds, residual chlorine, pigments, and odors. The sodium ion exchanger (resin softener) removes calcium and magnesium ions to reduce water hardness, preventing scale deposition on RO membranes. The precision (micron) filter captures fine colloidal particles, reducing turbidity to 1 degree before the RO stage.
The RO module uses Hydranautics membranes with imported high-pressure pumps. The system achieves soluble salt rejection of ≥97% and colloid, bacteria, and organic matter rejection of ≥99%. A PLC-controlled interface monitors operating pressure, flow rate, and conductivity. The compact skid structure minimizes installation footprint.
A UV sterilizer neutralizes bacteria that pass the RO membrane, providing primary disinfection. An ozone generator paired with an SUS 316 mixing tower delivers secondary disinfection, addressing residual microorganisms including viruses and chlorine-resistant bacteria.

The eight standard models (KM-1 through KM-20) provide a graduated capacity range from 1 to 20 tons per hour, allowing commercial users to select a unit matching daily water demand. Motor power ranges from 1.5kW to 30kW, with membrane configurations using 4040-type elements for smaller models and 8040-type elements for KM-3 and above. The stainless steel 304 frame and piping resist corrosion in wet operating environments, while the SUS 316 ozone mixing tower withstands ozone oxidation. The system's low-energy design reduces long-term operational electricity cost, and the automated control panel simplifies monitoring and parameter adjustment.
King Machine provides system design based on inlet water quality analysis, factory assembly and testing, and on-site commissioning. The standard warranty covers 12 months, with membrane and consumable replacement schedules specified in the operation manual. Spare parts including membrane elements, pumps, and sensors are available for dispatch. Technical support includes remote troubleshooting and guidance for routine maintenance such as membrane cleaning and filter cartridge replacement.
This system serves drinking water bottling plants, community water supply stations, beverage production facilities requiring purified water as raw material, food processing plants, and industrial process water treatment. It can be configured as a standalone unit or integrated into a complete water factory line including bottle washing, filling, capping, and packaging equipment. Customization options include additional pretreatment stages for high-turbidity or high-hardness inlet water, dual-pass RO for higher purity requirements, and EDI (Electrodeionization) modules for ultra-pure water applications.
The standard model range covers 1 to 20 tons per hour (1,000L/h to 20,000L/h), with eight models available from KM-1 to KM-20.
The system uses Hydranautics (USA) reverse-osmosis membranes, achieving soluble salt rejection of ≥97% and colloid/bacteria rejection of ≥99%.
Main structural components and piping are stainless steel 304. The ozone mixing tower uses SUS 316 for enhanced ozone and corrosion resistance.
The standard configuration includes silica sand filtration, active carbon filtration, sodium ion exchange softening, and precision (micron) filtration before the RO stage.
