Softener units upstream of salt electrolysis systems ensure that the process water is fully softened. Residual hardness in water after being treated with a softener forms deposits on the surface of cell diaphragms and reduces the lifetime of the cell packages causing high operating costs. To prevent this, it is important to test residual hardness in the operating water.
A sampling point and a three-way valve shall be installed in the operating water pipeline in flow direction between the softener unit and the salt electrolysis systems. After passing the sampling point, the softened water is transferred to the analysis instrument. The maximum limit is 0,25 °dH. The water must be drained using a three-way valve until no residual hardness can be measured after that the water can be used as process water for the salt electrolysis system.
With the equipment the Testomat ® family Testomat 2000 ®, Testomat ECO ® or Testomat ® 808 you can permanently monitor the residual hardness and reliably protect the membrane cells of the salt electrolysis system.
