The use of bioindication to determine the possibility of sludge recovery after biological treatment of wastewater

Abstract

These studies were conducted to test the hypothesis that sewage sludge from Lviv municipal wastewater treatment plants (LMWWTP) facilities can be used to create a substrate that can be used for biological reclamation. The qualitative composition of sewage sludge from Lviv municipal wastewater treatment plants is determined. The study of bioindication of a mixture of sludge with dark gray soil was carried out in two stages, which showed a significant difference between fresh and settled sludge. Possible conditions for the use of sludge in the substrate are presented.
