NEW CHALLENGES IN THE DAIRY WASTEWATER TREATMENT

Alla CHOBAN, Igor WINKLER

Abstract

The efficiencies of three different dairy wastewater treatment technologies have been analyzed and compared on example of several milk, cheese and butter making facilities. It is shown that the standalone mechanical treatment is completely inefficient while the required clarification cannot be ensured by regular aerobic bio-treatment also because of rather unstable pH value in the wastewater. The modified landfill bio-treatment method involving seeding the spots with Chlorella is discussed as more stable, effective and less expensive alternative technology for the dairy wastewater treatment.
