Abstract

Sewage treatment processes conducted in small sewage treatment plants are always the source of the specific quantity of sludge. It is the noxious product, with high hydration reaching 99%. Their composition differs in wide range, depending on the kind of wastes treated and technological processes in which they are generated.


The appropriate using and dosing of sludge improves the soil structure, allows feeding it with nutrients, but conducted wrongly would result in environment contamination and pollution of layers situated below, including underground waters.


Sludge character and structure influence decidedly onto the water contents, what is connected with its volume. Neutralisation of sludge having large volume is not cost effective and is dangerous for the environment. Therefore, the dewatering processes effectiveness is important
