Wastewater treatment plant PURE - BLK®

The peculiarity of the PURE-BLK® technology is that after the biodegradation in separate anaerobic, anoxic and oxic spaces, the phase separation takes place in a longitudinally designed post-settler. The dissolved organic materials in the wastewater are transformed into carbon dioxide, water and biomass by microorganisms. Continuous aeration is required for this technology via fine bubble deep aeration units. The quantity of the input oxygen can be controlled via measurements by an oxygen probe; aeration is programmable for denitrification and for lowest energy consumption. This two or multi-lined system is provides scaling opportunities and technological flexibility. Thus the system and WTTP can easily and effectively manage increased hydraulic capacity demands due to growing population and sewerage connections. More lines mean higher operational security in case of sludge bulking. TWO OR MULTI-LINED SYSTEM PROVIDES SCALING OPPORTUNITIES TECHNOLOGICAL FLEXIBILITY ANAEROBIC ANOXIC BASIN – FOR DENITRIFICATION PROCESSES AEROBIC BASIN – FOR BIODEGRADATION AND REMOVAL OF ORGANIC MATERIAL AND NH3 CHEMICAL DOSING FOR PHOSPHOROUS REMOVAL PURPOSES TREATED WATER AND SLUDGE SEPARATION SLUDGE REMOVAL SLUDGE RECIRCULATION INTO THE BIOLOGICAL BASIN EXCESS SLUDGE REMOVAL, FURTHER CONCENTRATION AND / OR DEWATERING MAY BE REQUIRED The specialty of the PURE-BLK® technology is that after biodegradation in isolated anaerobic, anoxic and oxic units, phase separation is done in a longitudinal designed secondary sedimentation basin. This two or multi-lined technology is recommended for WWTPs where the maximum hydraulic capacity is between 500 – 1500 m3/d.
