Using the hulls of industrial hemp in urban surface waste water treatment

Abstract

Environmental pollution is one of the most serious problems that cities around the world are facing. Despite strict governmental policies in environmental laws and attempts by various countries to convert to closed-loop economies, the water, air, and soil pollution remains a pressing issue. One possible solution to this problem is to use phytogenic waste as a raw material for the production of sorbents to treat waste water. Recycling phytogenic waste in this manner solves several problems simultaneously: disposal of several tons of industrial and agricultural waste; increasing the effectiveness of water treatment; reducing the costs of water treatment; creation and use of an environmentally-friendly material. The article presents a complex study on the possibilities of using phyto enic waste from hemp production (hemp hulls) as a sorbent for the treatment of surface waste water in urban territories. The current state of the hemp industry and the prospects for its development are examined. A microanalysis of the composition of hemp hulls has been conducted on a JEOL JSM-6460 LV electron scanning microscope. The sorption capacity of hemp hulls at varying conditions has been examined.
