Decalcifying flow conduit system by supplying first amount of descaling agent as saturated solution into reservoir in flow conduit system for first time interval for first period of time, and supplying further amount of descaling agent

摘要

The method comprises supplying a first amount of a descaling agent (2) as a saturated solution into a reservoir (1) in a flow conduit system for a first time interval for a first period of time, and supplying a further amount of the descaling agent as the saturated solution into the reservoir in the flow conduit system for a further time interval for a further period of time. The first time interval, in which a descaling process is carried out, is 18-48 hours. The first amount of descaling agent is less than other. The first amount descaling agent has a concentration of 20 mmol/l.

The first time interval, in which a descaling process is carried out, is 18-48 hours. The first amount of descaling agent is less than other. The first amount descaling agent has a concentration of 20 mmol/l. The further amount descaling agent has a concentration of 30-40 mmol/l. The further time interval, in which the descaling process takes place, is 1-3 months. The interval of the action of the descaling agent to the Flow conduit system is determined or set base on used frequency and/or carbonate hardness of the water.
