Removal of Biogenic Compounds from Sewage Water in a Culture of Euglena Gracilis (EUGLENOPHYTA)

This research presents experimental studies of wastewater treatment by microalgae. Discharge of insufficiently treated wastewater from nutrients into water bodies is one of the most common causes of eutrophication. Aquatic ecosystems respond to nutrient enrichment primarily by the intensive development of cyanobacteria. Their rapid reproduction causes “blooming” of water, which leads to oxygen deficiency and mass death of fish and other aquatic organisms. Removal of nitrogen and phosphorous compounds from sewage water in a culture of Euglena gracilis was investigated. The ability of Euglena gracilis for 7 days almost completely to remove ammonium nitrogen and phosphorus phosphates from the studied wastewater was established.
