Under normal circumstances, the water treatment process is largely similar:
Coarse filtration(Multi-media or sand filtration, etc)->Special filtration(Activated carbon orKDFSuch as)->Softening(Ion exchange)->Precision filtration(PPCotton filter elements, etc)->Purity treatment(ROOr nanofiltration, etc)->Post-processing(A carbon filter for texture)and(Ultraviolet lamps, etc.)
At present, in our daily life, the household water treatment systems we may encounter mainly include different types such as filtration, softening, and purification.
Filtration: Domestic miscellaneous water can be treated by filtration alone if you don't want to invest too much or the hardness of the raw water is not high(The hardness of the raw water is3mmolAs follows)Most domestic water is sufficient after precise filtration treatment.
Softening: It is mainly to remove the hardness in water, prevent scaling, and reduce the impact of hardness on life and health. It is needed in most areas of the north.
Purification treatment: The common method is to use reverse osmosis to treat water. Theoretically speaking, the water after treatment is pure water for daily drinking(It's the same as the bottled or barreled pure water we purchase)After removing the vast majority of ions from the water, this kind of water can be drunk directly.
Post-treatment: Mainly used for carbon filtration for taste or(KDFOr ultraviolet lamp)Since the taste of pure water is not very ideal, it is generally necessary to use a post-activated carbon filter. Some configurations are equipped with small water tanks, which may cause slight contamination(The equipment and pipelines may also be slightly contaminated)Small purple light tubes can be used.KDFIt is a special high-purity alloy material, mainly used to remove some special components, and in most cases, it is installed in front of reverse osmosis.
In household Settings, the recommended filters are generally:
Sand filter(Use fully automatic or manual sand filter tanks)-->Activated carbon filter element(If there is sufficient installation space, it is recommended to use20"Components)-->Fine filtration or ultrafiltration(It can be used20"Components)-->Ultraviolet rays(orKDF).

Yuan LaiEDIThe ultra-pure water equipment uses electro-deionization technology.EDIElectrodeionization is a water purification method that combines the dual advantages of electrodialysis and ion exchange. It does not require acid-base chemical regeneration and can continuously and stably prepare high-purity ultrapure water. Under the action of a direct current electric field, ion separation in water is completed. At the same time, water is electrolyzed to generate hydrogen ions and hydroxide ions, achieving automatic regeneration of the resin without the need to stop the machine for manual regeneration. The pre-treatment combined with reverse osmosis can prevent oxidized substances from damaging the resin, ensuring stable effluent quality and widely meeting the high-standard water usage requirements of various industries.
The non-negative pressure water supply equipment can be directly connected to the municipal water supply network, making full use of the residual pressure of the original network for superimposed water supply. Fully enclosed operation does not require the construction of a domestic water tank, eliminating secondary pollution. Intelligent variable frequency voltage stabilization, energy-saving, quiet and easy installation, it is the preferred equipment for secondary water supply in high-rise residential buildings and commercial buildings.
Constant pressure water supply equipment is widely used in central air conditioning, floor heating, industrial closed-loop water circulation, and boiler systems. It integrates automatic pressure stabilization, automatic water replenishment, automatic exhaust, pressure relief and buffering functions. It stabilizes the pressure in the pipeline network, eliminates abnormal sounds caused by air blockage, and prevents damage from negative pressure and water shortage in the pipeline. It is an essential supporting equipment for HVAC and circulating water systems.
