Title: Chemical cleaning of scale
Inventor: ERA FUKUO
IPC: C02F5/12
Filed: 1979-05-29
Abstract: PURPOSE: To accelerate scale cleaning effect and to simultaneously facilitate discharge of stacked sludge from an equipment, by using a scale-removing agent essentially consisting of sulfamic acid with an auxiliary agent of high-molecular electrolyte.
