Use of multiple charged ionic compounds derived from polyamines for waste water clarification

A water clarification composition comprising:

• a compound or its salt and one or more water clarification composition agents, wherein the compound is derived from an aza-Michael Addition Reaction between a polyamine and an activated olefin having an ionic group according to the following formula
• wherein:
• X is NH or O;
• R2 is H, CH3, or an unsubstituted, linear or branched C2-C10 alkyl, alkenyl, or alkynyl group;
• R2′ is H, CH3, or an unsubstituted or substituted, linear or branched C1-C10 alkyl, alkenyl, alkynyl group, —COOH, —CH2COOH, Y′, or —(CH2)m—Y′;
• m is an integer of 2 to 4;
• R3 is absent or an unsubstituted, linear or branched C1-C30 alkylene group;
• Y is —NR4R5R6(+);
• Y′ is —COOH, —SO3H, —PO3H, —OSO3H, —OPO3H, or a salt thereof;
• and
• R4, R5, and R6 are independently a C1-C10 alkyl group;
• wherein the compound is a multiple charged cationic compound having 2 or more positive charges or anionic compound having 2 or more negative charges and wherein the water clarification composition reduces turbidity of the water system.
