What is the hardness of water?

Some metal cations in water combine with some anions. During the heating process of water, due to evaporation and concentration, they are prone to form scale, which adheres to the heated surface and affects heat conduction. The total concentration of these metal ions in water is called water hardness.

What are the commonly used water treatment processes and equipment?

Under normal circumstances, the water treatment process is largely similar: coarse filtration (multi-media or sand filtration, etc.)-> special filtration (activated carbon or KDF, etc.)-> softening (ion exchange)-> precision filtration (PP cotton filter core, etc.)-> purification treatment (RO or nanofiltration, etc.)-> post-treatment (carbon filtration for taste) and (ultraviolet lamp, etc.).

What is ultrafiltration?

Ultrafiltration in water treatment refers to a solution separation process driven by the pressure difference on both sides of the membrane and based on the principle of mechanical sieving. The operating pressure is usually 0.2-0.6MPa, and the separation pore size is 1nm-0.1μm. Ultrafiltration technology is widely used in the separation, concentration and purification of substances.

: EDI ultra-pure water system

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.

: Non-negative pressure water supply equipment

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

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.
