Anti-fouling　experiments　for　heat　transfer　enhancement　using　high-voltage　electrostatic　field　are　carried　out　by　static　and　dynamic　methods.　The　results　of　static　experiment　indicate　that,　under　the　high-voltage　electrostatic　field,　crystal　changes　in　configuration　from　hexahedron　to　branch　or　slice,　and　enlarges　in　size.　Furthermore,　the　results　of　dynamic　experiment　indicate　that,　the　fouling　resistance　decrease　extraordinarily　with　treatment　of　high-voltage　electrostatic　field,　and　anti-fouling　capability　of　solution　increases　with　high　flow　velocity.
