Impact Of Washings From Water Softener Regeneration To Municipal Sewage Systems And Home Sewage Treatment Plants - Viessmann AQUAHOME 20-N Installation And Operation Manual

Impact of washings from water softener regeneration to municipal sewage systems and home
sewage treatment plants.
The regeneration process of the AQUAHOME ion exchange water softeners generates washings in the
volume equivalent to 5% of the total volume of softened water, that are discharged to the sewage network.
Regeneration washings are tap water containing elevated levels of chlorides in the range between 100 and
3
155 mgCl/dm .
Discharge of washings containing the above referred amount of chlorides to municipal sewage systems is in
3
full compliance with regulations (the norm is set at 1000 mgCl/dm ).
Discharge of regeneration washings to sewage chambers, cesspools or small biological home sewage
treatment plants should be executed with certain precautions.
In case of home sewage treatment plants, biological sludge is a breeding ground for bacteria, which
decompose the sediments into the liquid state. Naturally, but also due to the content of chlorines in
regeneration washings, the amount of bacteria may be insufficient. This may adversely impact the efficiency
of sewage treatment process. In order to prevent biodegradation processes it is recommended to use agents
that contain a wide range of bacteria. Such agents are an effective way to aid the sewage treatment process.
