Application of water treatment sludge for obtaining fertile soil

Abstract

The properties of soil obtained from the sludge of water treatment plants were investigated. A new recipe for obtaining soil from peat, river sand and sludge dehydrated with cotton dust was developed. The obtained soil is well structured, resistant to unfavourable mechanical and physical-chemical impacts. It is recommended for creating lawns, planting sports grounds, squares and road slopes. It can be used for filling landfills of solid municipal waste, for strengthening river banks and reservoirs, for soil protection, as well as for production of fertile soils in horticultural and urban farms, when growing vegetables, berries and flowers in greenhouses. The studied soil expands the range of plant nutrient mixtures, is based on the use of available raw materials, and is not difficult to prepare.
