The Path to the ChemFree System
There have been numerous non-chemical foam control technologies considered over the years, and some have been successful in dealing with very specific foaming problems. Some of these technologies include centrifugal systems, laser-based systems, ultra-sonics, and others. But, to date, none have found industry acceptance for foam control from end-to-end of an entire process line.
ChemFree did an exhaustive study of the various technologies in order to understand their strengths and weaknesses.
Of all the applicable technologies, ChemFree found that water sprays had the best potential for development. Sprays are well-known for their ability to condense foam and are used randomly to deal with acute foaming issues. Further, spraying systems have low capital, operating, and maintenance costs.
I’ve tried spray systems – they don’t work!
Oh, if we had a nickel for every time we’ve heard this. Until now, spraying technology had not been developed to a sufficient degree so as to solve foaming problems over an entire processing line.
In order to understand the foam dynamics, we found that foam generation needed to be considered as a total system, and not simply as a series of discrete foam “hot spots”.
The entrained air environment, how the foam is being generated, where it is being generated, the foam flow, the type of foam, the foam growth, and the relationship of the foam with the infrastructure all need to be considered as components of an entire foam system. ChemFree recognized this need and created a comprehensive method to analyze the foaming dynamics.
Based on this analysis, ChemFree developed their unique, innovative, and flexible patented Water Diffusion System (WDT™) to effectively control foam creation and growth.
