Biodegradable and effective starch flocculants are obtained by chemical and physical modification of starch. Novel flocculants can be obtained in form of powder or concentrated paste.
The invention allows to produce the cationic flocculants from starch for industrial and municipal wastewater and sludge processing. Such flocculants especially distinguished for their broad flocculation window.
