When wastewater is treated, sludge is produced. Ovivo thickeners are designed to continuously produce as thick a sludge as possible. Powered by heavy-duty drives, designed to handle the specified torque for 20 years of continuous operation, the sludge is gently mixed by rotating rake arms. This movement keeps it moving towards the center of the tank where it is removed. Ovivo thickeners offer sludge thickening for light, medium, or heavy-duty applications.
