Sludge & Odor Treatment

 

Sludge Treatment

Increased urbanization and the growth in wastewater treatment plants have led to a very large increase in the production of municipal sludge on a global level.

In order to deal with these increasing volumes, VWS' strategy is to produce sludge:

  • of a higher quality
  • in smaller quantities
  • that is safer

Odor Treatment

Municipal wastewaters generate foul smelling by-products that constitute a form of pollution.

These by-products are essentially made up of compounds containing : 

  • nitrogen (in particular ammonia and amine) ;
  • sulphur (hydrogen sulphide, mercaptan) .

Physical-chemical and biological techniques are used to remove them.

In far less quantities, organic compounds such as aldehydes, cetanes and hydrocarbons are also found in industrial gas.
