WASTEWATER TREATMENT PLANT
Wastewater is a mixture of domestic and industrial
wastes. It is more than 99% water, but the remainder
contains some ions, suspended solids and harmful
bacteria that must be removed before the water is
released.
Pretreatment
Large solids (i.e. those with a diameter of more than
2cm) and grit (heavy solids) are removed by screening.
These are disposed of in landfills.
Primary treatment
Primary treatment The water is left to stand so that
solids can sink to the bottom and oil and grease can
rise to the surface. The solids are scraped off the
bottom and the scum is washed off with water jets.
These two substances are combined to form sludge.
Secondary treatment
The sludge is further treated in 'sludge digesters': large
heated tanks in which its chemical decomposition is
catalyzed by microorganisms. The liquid is treated by
bacteria which break down the organic matter
remaining in solution.
