by a patent.
As a result of biological purification, clear, non-rotting water is obtained.
containing dissolved oxygen and nitrates. Biological treatment facilities
provide a significant reduction in pollution indicators for suspended substances and
After biological treatment, wastewater flows by gravity into secondary settling tanks,
working in a countercurrent scheme for more complete removal of phosphorus compounds and
sludge deposition. In the last zone of the bioreactor, a solution of the coagulant “Aqua Aurat 30” is supplied. To prepare the coagulant solution, a preparation unit is provided and
dosing of reagents consisting of plastic tanks for preparing and storing the solution
coagulant and dosing pumps for supplying the solution. The coagulant solution enters the consumables
tanks via gravity pipeline. To prepare a coagulant solution, use
purified and disinfected water.
