The possibility of the treatment of secondary pollutants in the form of concentrates of organic components (mainly proteins) and nutrients (nitrogen and phosphorus compounds) produced as a result of ultrafiltration of dairy wastewater was examined in this paper. Biological treatment using activated sludge was used to neutralize protein concentrates. This effectively reduced the content of both organic compounds as well as nitrogen and phosphorus in both dairy wastewater and retentate, which was concentrated twice in the ultrafiltration. However, the performance of activated sludge for the treatment of retentate concentrated four times in the ultrafiltration of dairy wastewater might be improved with bioaugmentation products.
