Deskripsi

Technological system of analyzed wastewater treatment plant is in part a biological bed of soil-reed in parallel arrangement. Unusual application is the application of two independent purification lines where in the second line, a bio-preparation is additionally dosed. The constructed wetland provides high removal of organic compounds expressed as BOD<sub>5</sub> and COD, as well as reducing the concentration of ammonia nitrogen and phosphates. This indicates a high performance of such a sewage treatment plant.
