Claim 0:
1. 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.
