A domestic alumina producer faced accelerated scaling in the evaporation section and excessive foaming in decomposition tanks due to high levels of impurities in its raw materials, adversely affecting production efficiency.

A leading steel manufacturer faced the dual challenge of severe scaling in its circulating cooling water system and the resulting equipment corrosion. Heat-exchanger efficiency declined, the risk of localized pipe corrosion and perforation increased, system pressure loss rose, and energy consumption grew, creating an urgent need for professional support to ensure stable operation.

A petrochemical company experienced reverse osmosis (RO) system failures caused by fluctuations in raw water quality. Unstable feedwater frequently led to sharp increases in operating pressure and excessive interstage differential pressure, resulting in a continual decline in salt rejection and a surge in permeate conductivity, seriously threatening production continuity.
