Technical Bulletin Demonstrates Compelling Performance of Rivertop Renewables’ Waterline™ CI for Cooling Water Systems

New glucaric-acid based corrosion inhibitor can reduce industrial discharge of phosphorous and simplify water treatment formulations

(May 18, 2016) MISSOULA, Mont. — Rivertop Renewables, a Montana-based novel chemicals company, announced that it has released its first technical bulletin for WaterlineTM CI, the company’s sustainable, high-performing corrosion inhibitor for use in industrial cooling water systems. The technical bulletin, the first in a series for this product line, offers performance comparisons with phosphate and shows Waterline CI as a viable alternative to the standard chemistries currently used in this multi-billion-dollar market. “The first commercial production runs and deliveries of Rivertop’s innovative corrosion inhibitors are now behind us, and these technical bulletins offer customers guidelines for use and integration into cooling water treatment programs,” said Mike Knauf, CEO of Rivertop. The testing described in the bulletin demonstrates how Waterline Cl performs as compared to orthophosphate, a standard inhibitor used to prevent corrosion in cooling water systems common to heavy industry. Phosphorous-based corrosion inhibitors often present a number of performance and operational challenges, and are subject to increased scrutiny by regulators for their environmental impact. Produced from renewable plant sugars and completely phosphorous-free, Waterline Cl forms a persistent, passivating film on steel surfaces and does not pose a fouling concern with calcium.  It achieves a lower and more stable corrosion rate over time as compared to phosphonate treatments used in HVAC systems.

By eliminating the need to formulate with stabilizing copolymers, Waterline CI enables water treaters to maintain a combined low total cost of formulation and in-use performance economics. Waterline products are manufactured at commercial scale in a plant operated by DTI in Danville, Virginia. Rivertop sells direct to water treatment service companies and the formulators who serve them.
