How to configure a suitable softened water system

It is well known that there are many benefits to using soft water treated with softened water equipment (see other articles on this site for details). Softened water equipment has been widely used in all walks of life, especially boilers, central air conditioners, and large-scale washing machines, as well as in food production, beverage shops, hotels, and baths. So how to determine the appropriate model when using soft water equipment? Here let Shanghai Hanshun Water Treatment Equipment Co., Ltd. come to answer for you.


1, first determine the actual water use time of the system: running time / hour of water consumption / average / peak /, the user needs continuous water supply? If you need to choose double tank double valve (D type) or double tank single valve system, do not need to Select single tank single valve system (S type).


2, determine the raw water related parameters: water pressure is satisfied? If it is not satisfied, you will need to add the original pump and even configure the original water tank. Whether the water source is groundwater, surface water (river, river, lake) or municipal tap water, water, solid particles, impurities, etc. What is the concentration of metal ions? Do you need to install a pre-filter?


3, the total hardness of raw water: In terms of specific types of softened water equipment, the high water hardness of the cycle will inevitably produce less water, and thus will have frequent regeneration, will shorten the resin life. In order to cope with this situation, it is necessary to increase the volume of the resin, which means the use of an increased size water softener. If you do not understand the texture of the water source, Shanghai Hanshun Water Treatment Equipment Co., Ltd. can provide you with free routine water quality analysis.

Softened Water Equipment Selection Table #1

In general:

When the raw water hardness is ≤3m.mol/L, you can select the time control type according to the above table, and calculate the maximum water production capacity of the equipment.

Raw water hardness ≤ 6m.mol/L can be selected according to the maximum water production capacity of the equipment in the table.

When the raw water hardness is ≤8m.mol/L, the average size of the water production capacity of the equipment is selected.

The raw water hardness is 8 to 10 m.mol/L, which is calculated by referring to the minimum amount of water produced by the equipment, or using a multi-stage system.

Raw water hardness ≥ 10m.mol/L, multi-level treatment must be used, the general two-stage treatment can meet the requirements.


4. Required soft water flow per unit (tons/hour): This is determined by the nature of the customer's equipment and requirements. The water softener model is selected accordingly.


5. Setting of cycle water production: After setting the softening water equipment model, the theoretical period water production (tons) can be determined based on the hardness of the raw water and the exchange capacity of the resin used.
