WASTEWATER TREATMENT PLANTS
The biological treatment method is a proven technology that has been delivering satisfactory results for many years. Panta Rei is an ever-evolving company and so are its products. We are able to offer a wide range of biological treatment solutions. Our standard plant, the activated sludge treatment with suspended biomass, has some of the lowest running and maintenance costs while the effluent characteristics are able to meet the European regulations.
The main objective of the biological treatment is the oxidation of the dissolved and particulate biodegradable constituents so that the polluting organic and inorganic compounds are removed or significantly reduced. The biological treatment process consists of several stages which are screening, primary sedimentation, feeding station, denitrification section, aerobic treatment plant, sedimentation with lamella pack clarifiers, thickening, dissolved oxygen increase unit, final filtration with disc filter, turbidity mesurements, UV disinfection and sludge dewatering.
In general, the actual water purification happens thanks to the bacterial metabolization; they process the organic substances internally, that is, they break the molecules into simpler compounds and generate carbon dioxide, water, gaseous nitrogen and, in less amount, other compounds depending on the inlet effluent characteristics.
