Fahrenheit is defined by itsGabrielD.Fahrenheir(1681-1736)The name is generally usedFIt indicates that its freezing point is31℉The boiling point is212℉.
The degree Celsius isAndersCelsius(1701-1744)Generally usedCIt indicates that its freezing point is0℃The boiling point is100℃.
The conversion formula between the two:C=5/9(F-32)F=9/5C+32
9.Some data related to the softener
1)Total switching capacity(Gram equivalent)=Resin volume(m3)×1000
Estimate based on the actual performance of the selected resin
If the maximum value that can be set on the device controller is smaller than the actual value, it should be set according to the controller's capacity
2)Total cycle water production
Q(m3)=Total switching capacity(mol)÷Hardness of raw water(mmol/L)
Q(m3)=Total switching capacity(Gram equivalent)÷Hardness of raw water(Milligram equivalent/l)
3)Periodic salt consumption
(Kilograms)=Total switching capacity(Gram equivalent)×(0.08~0.1)Kilograms/Gram equivalent
4)Calculation of salt liquid height in the salt valve:
The concentration of the salt solution is28-32%
The amount of brine required for periodic regeneration(m3)=(Periodic salt consumption(Kg)÷0.32)÷1000
Salt valve height(m)=Salt solution volume(m3)÷(3.14×Radius of the salt tank2)
*The amount of brine required for periodic regeneration(L)=(Periodic salt consumption(Kilograms)÷0.32)
Salt valve height(cm)=10×Salt solution volume(L)÷(3.14×Radius of the salt tank2(Decimeters)
The above are the commonly used units in water treatment. If you have any questions about water treatment, please consult Beijing Yuanlai Water Treatment Equipment Co., LTD.15With years of focus on the water treatment industry, you can trust us!

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.
