What is the hardness of water?

Released Date: May 06,2015 Article Source: Yuanlai Water Treatment

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.

The metal ion commonly found in natural water is calcium ion(Ca2+)And magnesium ions(Mg2+)It interacts with anions in water, such as carbonate ions(CO32-)Bicarbonate ions(HCO3-)Sulfate ions(SO42-)Chloride ion(CL-)And nitrate ions(NO3-)When combined together, they form hardness such as calcium and magnesium carbonates, bicarbonates, sulfates, chlorides, and nitrates. Metal ions such as iron and manganese in water can also form hardness, but since their content in natural water is very small, they can be disregarded. Therefore, usually justCa2+,Mg2+The total concentration is regarded as the hardness of water.

The hardness of water has a significant impact on the water used in boilers. Therefore, water should be softened or desalinated according to the water quality requirements of boilers with various parameters.

: 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.
