How to select water softener and boiler softening equipment?

Instructions for selection of softening equipment

1. Controller: Fully adopt American FLECK Fleck, AUTOTROL Atuzu automatic control valve, AQUAMATICYAKE Aike

2. Resin tank: optional: domestic RFP tank, metal lined plastic tank (PE lined)

3. Equipment operation control form:

  • L—flow type: Automatically restore when the prepared water volume reaches the set value, which is suitable for soft water preparation in all water supply systems.
  • S—Time type: Regenerative metering method controlled by time, suitable for system water supply with stable water consumption. The shortest regeneration cycle is 24 hours.

4. Available equipment combinations:

  1. Single control single bed: Stop water supply for 2 hours during the restoration period or continue to supply raw water (hard water bypass).
  2. Single control double bed: Alternate water supply, one use and one standby type.
  3. Double control double bed: Alternate water supply, one use and one standby type.
  4. Double control double bed: water supply at the same time, alternate regeneration.
  5. Multiple control beds: Three or more resin tanks are used in parallel, suitable for large water supply systems.

As long as you understand and provide the following parameters to our technical department, you can more accurately select the softener that suits your company’s system equipment requirements.

  1. First of all, you need to provide the system that needs to use softened water: process water? heating? Cooling and replenishing? steamer? Steel smelting industry? Chemical and pharmaceutical industry?
  2. System water time: clear running time/hour water consumption/average value/peak flow rate/
    Does the user need continuous water supply? If necessary, choose the single-valve, double-tank or double-control twin-bed series, otherwise, the single-valve, single-tank system can be selected.
  3. The total hardness of the source water? : Is the water source municipal tap water? groundwater? For surface water sources (river, river, lake water), you need to provide the raw water hardness of the area where it is used. For a certain type of water softener, the water hardness is high, and its periodic water production volume must be small, which leads to frequent regeneration. It is detrimental to the service life of the resin. In order to avoid this situation, the volume of resin should be increased, which means the choice of an enlarged model of water softener.
  4. The required soft water unit flow rate (tons/hour). This is determined by the nature and requirements of the user’s equipment, and the standard type of water softener is selected;
  5. Setting of cycle water volume
    After the water softener model is set, according to the hardness of the raw water, the exchange capacity of the resin used can determine the theoretical cycle water production (tons).
    Note: The type should be selected according to the hardness value of the raw water being processed. For high-hardness water (>8mmol/L), it is recommended to increase the one-level selection; when>12mmol/L, secondary softening or other methods should be used.
