Description
Problem
Water hardness.
Unit description
The water softener is designed to remove hardness (i.e. the calcium and magnesium ions contained in the water). The water treatment unit consists of two vessels filled with filter media, a fully automatic controller that manages the filter’s operation and two brine tanks. The filter medium is an ion exchange resin made specifically for water treatment.
Intended use
The unit is used when treated water must be available at all times (including during backwashing). The unit can be started in two ways: duplex unit (the filter vessels work alternately) or parallel unit (the filter vessels work at the same time but go into backwashing at different times).
Operating principle
In the unit, the calcium and magnesium ions dissolved in the water are replaced with sodium ions. The unit works fully automatically, performing backwashing, i.e. regeneration, according to consumption. The user’s task is to make sure there is always enough of a supply of salt tablets in the brine tank. The installation site needs an electrical outlet and a drain connection.
