Lakeland Dairies improve water treatment
Lakeland Dairies in County Cavan, Ireland has upgraded its wastewater treatment plant by installing a Centriquip Centrifuge.
The CQ5000 machine has multiplied three-fold the amount of solids that can be removed from the plant every day, the firm reports.
Rory Farrell, environmental manager for Lakeland, said that the company had used the plant for approximately 30 years. The company had, however, outgrown its old equipment. “The Centriquip machine can put through 45 cubic metres per hour of sludge from the settling tanks,” he said.
The wastewater generated at the dairy is mostly a result of the CIP (cleaning-in-place) system used to wash processing equipment.
Lakeland uses two settling tanks to settle sludge as part of its wastewater treatment process. The new CQ5000 draws its feed from the bottom of these tanks and from two sludge-thickening tanks. It separates the clean water for return to the water treatment plant from the solid matter, which is used on land as a fertiliser.
