Case Study: Saint John’s University Achieves Permit Compliance and Improved Cooling Water Protection with Kurita America’s PhosZero Technology

Saint John’s University secures permit approval in 3 weeks with Kurita America

Saint John's University faced a challenge when its water discharge permit was renewed with significantly tighter restrictions, particularly on phosphorus levels. Their existing supplier could not develop a program to meet these new limits, prompting the university to contact Kurita America for assistance.

Kurita America implemented its unique PhosZero™ Technology, a phosphorus-free program that provided excellent corrosion and scale control. They also introduced a specialized hydrogen peroxide and peroxyacetic acid biocide blend, along with a neutralization step and an automation system. Kurita America secured regulatory approval within three weeks, and the program achieved full compliance with the permit while improving operational performance compared to the previous treatment.
