    • A method of controlling the fouling potential of macroinvertebrates, such as mollusks, in aqueous systems which comprises adding to the system an effective controlling amount of a water-soluble quaternary ammonium salt having the following structure: ##STR1## wherein R.sub.1 is an alkyl group having about 6 to 24 carbons; R.sub.2 is an alkyl, aryl or arylalkyl group having about 6 to 24 carbons; R.sub.3 and R.sub.4 are alkyl groups having about 1 to 4 carbons; and X is chloride, bromide, sulfate, bisulfate, nitrate or acetate. Preferably, the quaternary ammonium salt is water-soluble alkyl dimethyl benzyl ammonium chloride having an alkyl chain length from C.sub.6 to C.sub.24 and, most preferably, it has an alkyl distribution of about 40% C.sub.12, 50% C.sub.14 and 10% C.sub.16.
    • 一种控制含水系统中大型无脊椎动物如软体动物的结垢潜力的方法,包括向该体系中加入有效控制量的具有以下结构的水溶性季铵盐:其中R1是具有 约6至24个碳; R2是具有约6-24个碳原子的烷基,芳基或芳基烷基; R3和R4是具有约1至4个碳的烷基; X为氯化物,溴化物,硫酸盐,硫酸氢盐,硝酸盐或乙酸盐。 优选地,季铵盐是具有C 6至C 24烷基链长度的水溶性烷基二甲基苄基氯化铵,最优选其烷基分布为约40%C 12,50%C 14和10%C 16。
