If they continue to be in the wastewater, they result in overfertilisation of water bodies and enrichment with nutrients, which can result in worthless plant expansion (eutrophication) harmful into the ecosystem.
Expense in wastewater treatment systems is shifting from new design jobs to routine maintenance of original capacity and function of services (asset management).
As sludge is settling to The underside from the sedimentation tanks, lighter products are floating for the surface.
The micro organism kind activated sludge flocks that float freely within the water.
