Automatic electromechanical water softener for domestic – industrial use

Carbotecnia’s line of domestic and industrial softeners

The softeners are designed for the treatment of hard water 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).

Automatic time-based water softener:

Simple automatic water softener by time: single tank equipment with cationic resin, with automatic control valve for time-based regeneration (regenerates every certain number of days or on a certain day of the week). Recommended for domestic or industrial use, with non-variable consumption and operation of less than 22 h.

Advantages:

  • Reduction of tartar incrustations, which cause stains on glassware, cutlery, bathroom and kitchen furniture.
  • Savings in detergent and fabric softener consumption.
  • Reduction of the sensation of dryness in hair and skin.
  • Prevention of scale formation in heaters.
  • Prevention of clogging and scaling of pipes.
  • Protection of industrial equipment and systems.
  • Care of equipment in restaurant kitchens or industrial canteens.
  • Conditioning of water lines of a production line.

Operating conditions:

  • System operating pressure: 20 to 100 psi.
  • Maximum operating temperature: 49 °C.
  • Feed water:
  • Pre-filtration: 5 microns
  • Inlet pH: 6.0 – 10.0
  • Free chlorine: < 0.5 mg/L
  • Turbidity: < 5.0 NTU

This line is available in tanks from 8×44″ to 63×83″, to treat from 1.5 to 310 gpm of instantaneous flow.

To select the most suitable softener for your needs, you must know the maximum flow rate required. If you have any doubts about the selection, please contact one of our consultants.

To select the most suitable water softener for your needs, you must know the maximum flow rate required. If you have any doubts about the selection, please contact one of our consultants.

Calculation of water 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.
