The aliphatic amine is selected from among the following: CH,CH,CH,CH,CH,CH,CH,CH,CH,CH,NH,, R—O—(CH,),NH,and R—O—(CH,),NH(CH,),NH,wherein R is an aliphatic hydrocarbon having from 8 to 10 carbon atoms, R optionally having additional ether linkages such as C,H,—(O—CH,CH,),′, and wherein n is an integer from 8 to 10 and n′ is an integer from 1 to 5. When the aqueous solution is added to the water, flocculus or precipitants are substantially not formed in the water proximate to the point of addition.
