Simple manual softener domestic – commercial

The line of domestic – commercial manual softeners

They are designed for hard water treatment in residential and commercial applications, where water consumption is less than 22 hours.

For an adequate cost-benefit ratio, it is recommended to use it to soften water with total hardness ≥ 200 mg/L (ppm).

This line is available in tanks from 8×44″ to 24×72″, to treat from 1.5 to 45 gpm of instantaneous flow.

Simple manual operation softener

Simple manual softeners: single tank equipment with cationic resin, with manual control valve for regeneration by time (manually the days calculated in your water analysis), recommended for domestic or commercial use, with non-variable consumption and operation less than 22 h.

To select the most suitable softener for your needs, you must know the quality of the water to be treated. If you have any doubts about the selection, please contact one of our consultants.

Advantages:

  • Reduction of tartar formation, which causes stains and incrustations on glassware, cutlery, bathroom and kitchen furniture.
  • Savings in the consumption of detergents and fabric softeners.
  • Reduction of the sensation of dryness in hair and skin.
  • Prevention of scale formation in heaters.
  • Prevention of pipe clogging.
  • Operating conditions:
  • System operating pressure: 20 to 100 psi.
  • Max. operating temperature: 49 °C.
  • Feed water:
  • Prefiltration: 5 ?m
  • Inlet pH: 6.0 – 10.0
  • Free chlorine: < 0.5 mg/L
  • Turbidity: < 5.0 NTU

Calculation of the softener capacity:

Water hardness is usually expressed in mg/l CaCO3, also known as parts per million (ppm), but can also be expressed in other units, such as grains per gallon (gpg), 1 gpg = 17.1 mg/L or 17.1 ppm.

To calculate the volume of water that your equipment will be able to soften, you must know the hardness of the water to be treated in gpg and the capacity of the softener, which is directly related to the salt with which the equipment is regenerated.

In the specifications table, there are two columns, one for design capacity and the other for maximum capacity, expressed in grams of hardness per unit. Each one specifies the salt with which the resin must be regenerated to obtain this capacity.

Once the size of the equipment has been selected, the value of the equipment capacity (in gr) is taken and divided by the water hardness (in gpg). The result is the amount of gallons of water the equipment can treat before saturation. When consumption is not variable, this flow can be transformed into days by dividing the number of gallons that can be treated by the consumption per day.
