Introducing advanced nutrient removal technologies at the Moscow wastewater treatment facilities

Summary

The results of introducing energy efficient process designs of biological nutrient removal from low concentrated municipal wastewater are presented. At 22–25 mg/l ammonia nitrogen and 2.3–2.5 mg/l phosphate-phosphorus concentrations in the incoming wastewater the stable phosphorus removal was obtained when using the process design of the Cape Town University (UCT). At higher concentrations of wastewater (30–40 mg/l ammonia nitrogen and 3.3–4 mg/l phosphate-phosphorus) the process design of the Hanover University (MISAH) and the modified UCT process design developed by Mosvodokanal MPUE research workers were most efficient.
