The DSW integrated direct - drinking water equipment features an integrated product design with a compact and reasonable structure, occupying a small footprint. It can combine different modules according to the quality of tap water to achieve modular production.

Ultrafiltration can intercept large - molecule harmful substances such as bacteria and viruses, but it cannot remove substances like heavy metals, so the water cannot be drunk directly. Reverse osmosis has a filtration pore size of 0.1 nanometers, with a removal rate of substances in water of over 99%. The water produced contains no minerals and is not suitable for long - term consumption. Nanofiltration, with a filtration pore size of 1 nanometer, can intercept all harmful substances including heavy metals, bacteria, and viruses, while retaining the minerals and trace elements in the original water. The water quality of the effluent is suitable for long - term drinking.
Multi - stage Precision Filtration and Purification System
Pure, Fresh, Healthy, Sweet
01 - Multi - medium Filtration System
Removes sediment, rust, colloids, and suspended solids.
02 - Activated Carbon Filtration System
Removes color, organic pollutants, heavy metal ions, and reduces residual chlorine.
03 - Water Softening Filtration System
Reduces water hardness, removes calcium and magnesium ions in water, and effectively prevents scaling.
04 - Prefiltration System
Further filters out impurities and fine particles to prevent particles from damaging the membrane.
05 - Ultrafiltration System
Further reduces turbidity, filters out bacteria and viruses, and further purifies the water quality.
06 - Nanofiltration Membrane System
It is the core component of the direct - drinking water production process, effectively removing microorganisms, heavy metals, polyvalent salts, and organic pollutants in water. The water quality of the effluent is close to pure water, and some trace elements can be retained. The treated water can be directly consumed, which is the first - choice for international direct - drinking water treatment processes.
07 - Ozone Sterilization System
Reduces the secondary pollution of bacteria, with a sterilization rate of up to 99.9% or more, ensuring the water quality is fresh.
08 - Filter - type Ultraviolet Sterilization System
A physical sterilization technology that destroys the DNA structure of microorganisms, eliminating viruses, bacteria, etc. in water.
09 - Return - water Prefiltration System
A closed - loop circulating water pipeline is set up to realize the circulation and disinfection of water in the entire water supply network. The system can intelligently determine the water quality. The water that meets the standard after prefiltration will flow back to the clean water tank, and the unqualified water will flow to the intermediate water tank for recirculation and filtration, preventing secondary pollution during the water supply process and improving the water production rate.
10 - Return - water Circulation Filtration System
When the return water is determined to be unqualified by the intelligent system after passing through the prefiltration system, it will automatically return to the intermediate water tank for recirculation and filtration, preventing secondary pollution during the water supply process and improving the water production rate.
