Sludge Treatment

Sludge originates from the treatment of waste water. Due to the physical and chemical processes involved in the treatment, the sludge concentrates heavy metals and poorly biodegradable trace organic compounds as well as potentially pathogenic organisms that are present in waste waters.

However Sludge is rich in nutrients, like nitrogen and phosphorous and contains valuable organic matter that is useful when soils are depleted or subject to erosion. The organic matter and nutrients are the two main elements that make the spreading of this kind of waste on land (as a fertiliser or an organic soil improver) inherently suitable.
