418 Maleic Acid-Based Corrosion Inhibitors: Expanding the Water Treatment Toolbox with Mike Standish

Corrosion control is fundamental to the success of any water treatment program, but how often do we question the limitations of the tools we rely on? In this episode of Scaling UP! H2O, host Trace Blackmore welcomes back returning guest Mike Standish, Vice President of Water Additives at MFG Chemical, to explore the evolving role of maleic acid-based corrosion inhibitors in industrial water treatment. Drawing on decades of expertise, Mike shares practical insights into when — and when not — to use these innovative solutions to meet today's complex challenges.

Understanding the Corrosion Control Toolbox 

Mike Standish opens the conversation by reframing corrosion control strategies through the lens of a toolbox analogy. With limited primary approaches — from phosphate-based to organic and metal-based chemistries — the success of corrosion management depends on matching the right tool to the right application. Mike stresses the importance of avoiding overcomplication and focusing on the fundamental chemical pathways for mild steel protection.

Organic vs. Inorganic Approaches 

The discussion turns to the critical differences between organic and inorganic inhibitors. While inorganic phosphates remain cost-effective mainstays, organic phosphonates, including maleic acid-derived materials, offer advantages in high pH, high hardness, and oxidizing environments. Mike emphasizes that “organic” in water treatment bears no relation to natural or sustainable products, a frequent misconception among newcomers to the industry.

Why Maleic Acid-Based Inhibitors Matter 

Maleic acid phosphonates distinguish themselves with exceptional oxidant stability, a feature increasingly necessary as continuous halogenation becomes standard practice. Mike explains the chemistry behind maleic acid derivatives and how the ability to tailor molecular structures creates flexibility for specific field conditions — such as scaling tendencies, pH control, and calcium carbonate formation risks.

Best Practices for Application and Measurement 

Field success with maleic acid-based inhibitors hinges on proper dosage and testing. Mike shares lessons from real-world trials, emphasizing that underfeeding is a common mistake that compromises corrosion rates. Accurate differentiation between orthophosphate and phosphonate concentrations is vital for precise monitoring, and bench testing must closely simulate real-world surface-to-volume ratios to yield reliable predictions.

The Future of Corrosion Control 

In a forward-looking discussion, Mike predicts that industry consolidation will trigger a second wave of entrepreneurial water treatment companies. His vision underscores the ongoing need for technical excellence, adaptability, and innovation in corrosion management practices as the industry evolves. 

This episode challenges water treatment professionals to rethink their corrosion strategies with a sharper, more informed approach. Maleic acid-based inhibitors are not a universal solution, but when applied thoughtfully, they offer powerful advantages for specific operational demands.
