FOOD AND DRINK – LIFT STATIONS/PUMP STATIONS

Food Manufacturer, UK

 
A factory in the south of England, and it’s wastewater treatment plant, designed and constructed to produce fruit jams. Following a change of ownership, suet is now manufactured in the factory.

The Problem

Jam contains large particles which need screening out, while allowing some smaller particles to remain in the final product. This factory had two large filter screens, each about one metre square, for this task. While the factory produced jam, these filters only needed a fairly fast clean as part of the normal end-of-shift washdown.

Unfortunately, suet is a much more viscous substance. The filters blocked quickly. The factory manager diverted the wastewater through only one filter. This took one hour to completely block. The flow was then diverted through the other filter, while two men took at least twenty minutes to physically unblock the first filter. Having only one filter in operation at a time also reduced the amount of suet the factory could produce.

As the factory operated 24 hours per day, this meant, in effect, that one worker was employed just to clean the filters during every shift.

The Solution

We recommended adding EnBac® B220 to the wastewater.

The Results

After some experimentation, we agreed on a sensible dose which meant that the filters took about six hours to block. This dramatically reduced the staff costs incurred in running this production line and meant that for some of each shift, two filters could be in operation, so increasing production.

Using EnBac® B220 cut costs and increased production.

The factory now no longer produces Suet. It has installed a new wastewater treatment plant and produces cider.
