Claims20
A method of improving an evaporative performance of a porous evaporative media in a cooling system that utilizes water evaporation for heat transfer, the method comprising contacting the porous evaporative media with a scale relocating-effective amount of a nonionic surfactant and no antiscalant,
- wherein the nonionic surfactant comprises a C8-C22 alcohol ethoxylate, a C8-C22 ethoxylate, a C8-C22 alkyl phenol ethoxylate, a terminally blocked C8-C22 alcohol polyethylene glycol ether, a monododecyl ether, a nonoxynol, an ethoxylated C8-C22 ester, an ethoxylated amine, a C8-C22 amide, a polyethoxylated tallow amine, a poloxamer, a C8-C22 ester of a polyhydroxy compound, an alkyl polyglucoside, myristamine oxide, a polyethylene oxide polymer, a polypropylene polymer, a polyethylene oxide/polypropylene oxide copolymer, octaethylene glycol monododecyl ether, pentaethylene glycol monododecyl ether, Triton X-100, cocamide monoethanolamine, cocamide diethanolamine, glycerol monostearate, glycerol monolaurate, sorbitan monolaurate, sorbitan monostearate, sorbitan tristearate, Tween 20, Tween 40, Tween 60, Tween 80, decyl glucoside, lauryl glucoside, octyl glucoside, or a combination thereof.
