The problem of sewage freezing
Thread Content
What to do if the wastewater in a sewage treatment plant freezes in winter? In the north, winters are around minus ten degrees or so
The pipes are insulated, and the tank is heated using steam coils
It is possible to reduce the number of operating processing units in order to maintain the minimum temperature required for biochemical processes.
Proper insulation measures must be taken, as well as heating; in the north, water treatment efficiency drops significantly during winter
1. Heat the wastewater. 2. Insulate the system. 3. Ensure the wastewater system flows continuously as much as possible.
I believe the following methods can be used to increase the temperature: 1. Mixing waste heat wastewater with other wastewater; 2. Introducing steam condensate into the wastewater system; 3. Directly heating with steam
