Szukana fraza: [Abstract = "The treatment plant is characterized by a very high variability of wastewater inflow during the year due to periodic inflow of wastewater from tourist resorts in Łagów. The average efficiency of removing pollutants from wastewater was\: BOD5 \- 98.5%, COD \- 92.8%, total suspended solids \- 93.2%, total nitrogen \- 86.1% and total phosphorus \- 69.5%. The study showed that the use of a hydroponic lagoon in the technological system improved the efficiency of wastewater treatment by 1.7% for BOD5, 0.9% \- COD, total suspended solids by 4.3%, 6.4% for total nitrogen and total phosphorus \- 3.3%."]
