The water treatment industry has long relied on phosphate-based formulations to manage mild corrosion and scale in cooling tower systems and this describes novel biobased building block chemicals which address the deficiencies that traditional non-phosphorus technologies exhibit.

The water treatment industry has relied on phosphate-based formulations to manage mild corrosion and scale in cooling tower systems since the regulation of hexavalent chromium-based programs. However, phosphate-based technologies are bringing significant challenges to the formulators:

1. The need to add chemistries into the formulations to manage the calcium phosphate depositions
2. Stricter environmental regulations to control the phosphorus discharge
3. Phosphorous shortage is limiting the availability of phosphorous-containing water treatment ingredients. This situation has forced the industry into a re-evaluation of formulation alternatives.

Solugen has developed a second generation of bio-based building blocks that address these challenges without compromising performance. These technologies are manufactured by a novel chemoenzymatic process that imparts unique properties to effectively manage the naturally occurring corrosion inhibiting species in cooling tower water. This paper exhibits the benefits of using Solugen technologies in non-phosphorous formulations to achieve performance, reduce supply chain stress and comply with environmental regulations. Suggested formulations are proposed with performance data incorporated.
