Biochemica UK Ltd has reduced water demand, and im turn overall costs for a food processing plant by implementing water use process improvements.
The factory, which washes and processes vegetables re-circulates water back around its wash system without any treatment, meaning that produce was continually washed in dirty water. This has a number of implications, not least the need for regular refreshing of the process with clean water, which only stayed clean for an initial short period.
The solution was to pass the waste water through a centrifuge-decanter with a view to removing the solids as a dry waste material and clean up the water to an acceptable standard for reuse. As a result, the requirement for mains water to top up and/or refresh the system was reduced, thereby reducing costs, as well as a number of other disposal benefits.
