Food processing plant saves water while protecting their ion exchange unit -- A Real World Documented Case Study #5.

How the Ronningen-Petter brand self-cleaning filter saved a food processing plant water while protecting their ion exchange unit.

SITUATION:

A food processor was removing contaminants from gelatin liquor with pressure leaf filters that were pre-coated with diatomaceous earth (DE).

The DE, however, would periodically break off, travel downstream, and plug the ion exchange unit. This resulted in two-days of downtime to allow employees to manually clean the column.

RONNINGEN-PETTER SOLUTION:

Based on these criteria, the food-processing plant installed a Ronningen-Petter brand self-cleaning filter to completely remove rust and scale, while allowing the quench polymer to flow freely.

In addition, automating the filter later helped the company minimize waste by saving water. How?

Operators in the past had been cleaning the filter too often and for too long a period. However, a Ronningen-Petter brand automation package began telling the filter precisely when cleaning was needed, and how long each cleaning cycle should be.

RESULTS:

After installing a self-cleaning filter, the column never plugged again -- this meant the filter paid for itself within eight months.
