Abstract

Wastewater treatment plants are essential in terms of environmental protection. The processes taking place into wastewater treatment plants are complex and require specialized machinery and equipment capable of operating in special conditions. Starting with the Sequential batch reactor (SBR) system (biological mechanical, chemical processes are carried out in the same basin), it could be reached a complex architecture with separate tanks, resulting scheme with predenitrification-nitrification, nitrification-postdenitrification, successive nitrification-denitrification basins or combined processes in oxidation ditches. ADIPUR wastewater treatment plant type is derived from SBR system, to which were added a secondary sedimentation tank and a recirculation circuit. In operation, ADIPUR system is tuned through adjustment of activated sludge concentration, dissolved oxygen concentration needed for pollutants oxidation, sludge recirculation flow, nitrification-denitrification process duration. There are proposed several technical solutions for ADIPUR wastewater treatment optimization based on system analysis through mathematical model used to assess the nitrogen dynamics, on the basis of mass conservation equations. Equipping this type of wastewater treatment plant with nitrogen monitoring equipment ensures process optimization and minimal operating cost.
