Application Case Studies

Case Study 1: Cooling Tower Biofouling in a Petrochemical Plant

A major petrochemical complex faced severe biofouling in its critical cooling water systems, leading to reduced heat exchange efficiency, increased energy consumption, and frequent maintenance. Traditional biocide treatments were proving insufficient against the complex microbial consortia, which included resistant strains.

• Solution: We implemented a biocide program utilizing our optimized isothiazolinones (CMIT/MIT 14%) as a primary treatment, applied via shock dosing. The program was designed following an on-site microbiological audit and a review of system parameters.
• Results: Within three weeks, microbiological counts in the cooling water decreased by over 95%. Heat transfer coefficients returned to optimal levels, resulting in an estimated 7% reduction in energy consumption. Biofilm accumulation on heat exchanger surfaces was significantly reduced, extending the interval between mechanical cleanings by 50%. The client reported enhanced system reliability and substantial operational savings.

Case Study 2: Preservation of Architectural Coatings

A leading paint manufacturer struggled with in-can spoilage of their water-based architectural coatings. Microbial growth during storage led to gas production, phase separation, and off-odors, causing significant product loss and reputational damage.

• Solution: After comprehensive compatibility testing and MIC determination against typical paint contaminants, our CMIT/MIT 1.5% formulation was integrated into their production process as an in-can preservative at a recommended dosage of 0.1-0.2% by weight.
• Results: The paint manufacturer observed a complete elimination of microbial spoilage during a 12-month accelerated aging test and real-world storage. Product viscosity, pH, and appearance remained stable. The effective preservation significantly reduced batch rejections and customer complaints, enhancing overall product quality and brand trust.
