Possibilities for the boring sludge property improvement for their recultivation

The issues of the coagulant use for the boring sludge physical property improvement are considered in the article. Comparative estimation of the coagulant influence on the boring sludge filtrational ability is given in the article. It is determined that aluminum sulphate and chloride calcium has appeared to be the most effective coagulant-ameliorant providing increased water filtration. The calcium carbonate didn't influence on the coagulation process in the alkaline environment conditions.
