The Path to Sustainable Foam Control

At the heart of every successful food processing company is a commitment to sustainability. One key area of the process that has lagged behind is the development of a foam control system that can cost-effectively reduce chemical usage to improve food safety. Many systems have been tried with little success. Systems such as laser-based technologies, ultrasonic bubble disruption and others have fallen short of the threshold required for true sustainability.

ChemFree did an exhaustive study of the various technologies in order to understand their strengths and weaknesses.

This study led to the development of a technological breakthrough for the food processing industry. This patented technology actually reduces CapX investment as well as operating and maintenance costs.

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”.

A truly sustainable solution would need to address the entrained air environment, how and where the foam is being generated, the foam flow, the type of foam, the foam growth, and the relationship of the foam to the plant’s infrastructure. ChemFree recognized this need and created a comprehensive method to analyze the foaming dynamics.

This analysis led to the development of the first sustainable, cost-effective foam control solution for the process food industry. The patented ChemFree WDT™ system incorporates mechanical foam remediation with chemical bubble reduction to form a complete foam management system that lowers overall operating costs while driving down the use of chemicals. The reduction of chemical use to control foam assures a safer end product as chemical residues on the final product are greatly reduced and in some cases, eliminated. The ChemFree WDT™ system delivers what the process industry has been searching for: A truly sustainable, cost-effective solution for total foam control.
