Sewer odour problems

COALSI solutions for odour pollution from the sewer.

Unpleasant odours from the sewer — causes and effects

‍

Bad odours from the sewer are caused by the decomposition of organic substances and the formation of hydrogen sulphide. These odors can occur more frequently, particularly during warm months or when water flow is low. They not only affect the quality of life, but also the environment of residential and commercial areas.

That is why COALSI has developed effective solutions against sewer odors, which neutralize odor-causing substances quickly and sustainably thanks to innovative activated carbon filter mats. The channel is not closed but can continue to breathe, which prevents corrosion and the associated expensive renovation work.

With the innovative filters from COALSI, odour pollution from the sewer can be significantly reduced:
