How does the sodium ion exchange water softening process reduce the alkalinity in the raw water?

Released Date: Feb 23,2016 Article Source: Yuanlai Water Treatment

The sodium ion exchange water softening method requires that the alkalinity of the raw water not be reduced during the softening process. When the alkalinity (pH value) in the raw water is too high, it will affect the quality of steam, increase the blowdown rate and raise the ineffective heat loss. The metal heating surfaces such as the drum may also become caustic embrittlement due to an excessively high PH value, which affects the operation and service life of the pot. Therefore, sulfuric acid solution should be added to the water after sodium ion exchange for neutralization treatment to reduce the alkalinity of the water. During the neutralization and acidification process, CO2 will be produced. A CO2 remover can be set up to remove it. When operating, pay attention to the control of the amount of acid added to prevent the boiler from being corroded by acid.

: 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.
