Process audit and technical-and-economic assessment of Velikiye Luki biological wastewater treatment plant reconstruction

Velikiye Luki biological wastewater treatment plant confronted serious challenges such as dramatic deterioration of incoming wastewater, high maintenance charges and low quality of wastewater treatment.
After process audit GSP-Project Ltd experts detected that aerobic biological treatment technology in use does not allow to meet wastewater treatment norms. Beside that they predicted wastewater treatment quality deterioration because of decrease in aeration equipment efficiency.
GSP-Poject Ltd specialists recommended to introduce nitri-denitrification technology as well as to install modern aeration and blower equipment. It will halve the energy consumption for aeration. The payback time is 2-3 years.
