How much water do you need?
"Today, we're operating at around 7 liters [1.8 gallons] water per bird, which is a very respectable figure. Marel's highly efficient poultry line certainly has a lot to do with this. However, we want to reduce water use still further, because 7 liters per bird doesn't solve our water shortage problem. The amount of water we had available was sufficient for the first phase of our processing plant, but we were significantly short for the second phase with its double shifts. Although we have our own borehole, the amount of pumped-up water allowed by the authorities, even together with tap water, is not enough, so we had no option but to recycle and reuse. Marel's BioBrane¹ concept turned out to be the ideal solution for situations where water is scarce and commercial water supply is an issue.
The initial design of the water treatment installation already assumed expansion. Civil infrastructures were prepared for it, lessening the effects of the transition to phase two."
Cranswick uses the Curieau system for water reuse. How much water are you reusing?
"In the second phase, about 50% of our wastewater has to be reused to make our water management process work. The Curieau system, however, succeeds in processing around 65% of our daily effluent flow."
