Oxi-Plus is an oxidizing biocide that is transforming microbial control for power generation. At a Midwest coal-fired power generation facility, it solved a persistent cooling-water fouling problem that conventional biocides could not.
The customer challenge
A Midwest coal-fired power generation facility encountered significant challenges in managing microbial growth within the cooling water system. Its reliance on previous biocide solutions, namely sodium hypochlorite, bromine, and mono-chloramine, proved problematic due to the pH-dependent efficiency of sodium hypochlorite, which mandated the addition of sulfuric acid to regulate pH. Additionally, the facility had adopted a competitor's biocide technology based on mono-chloramine, which required on-site generation and led to several months of inadequate treatment.
The consequences were substantial: heightened microbial contamination within the cooling tower, elevated back pressure, decreased operational efficiency, visible microbial fouling, and slime in the condenser head boxes.
Our solution
Water Tech, Inc. proposed the adoption of Oxi-Plus, a biocide formed from the reaction of sodium hypochlorite (bleach) with a non-toxic mineral catalyst, as a solution for water disinfection. Oxi-Plus stands out with its versatility, effectively operating across various pH levels, making it suitable for seasonal pH fluctuations.
This innovative oxidant offers significant safety and environmental advantages, as it decomposes into harmless byproducts, contributing to enhanced safety and compliance with environmental standards. Oxi-Plus maintains its effectiveness over an extended period, ensuring consistent microbial control. It is also a cost-effective choice, reducing total operating costs, eliminating the need for capital expenditure, and enabling straightforward monitoring through Oxidation-Reduction Potential (ORP) or chlorine residual measurements.
