Application of multi-criterial analysis to evaluate the method of utilization of sludge from small wastewater treatment plants with sustainable development of rural areas

A multi-criterial analysis has been proposed for choosing the optimal method of dewatering and final disposal of sludge from small wastewater treatment plants. A multi-criterial analysis is a method of compromise programming, selecting the best solution from four possible technological variants of sludge treatment. Based on these calculations, the best method from 4 variants was selected. It can be used in selection of optimal solution of sludge treatment and designing of small communities in rural areas.
