Sludge scraping
The ZICKERT Shark sludge scraping system from WesTech Engineering has concave forward faces to transport sediment toward a sludge pit. During the return movement, wedge-shaped rear faces slide under the sludge blanket, providing uninterrupted transport. The system is designed for rectangular tanks and lamella plate clarifiers and works in all sedimentation processes, including grit chambers. It can be powered by hydraulic or electric motors and can be pushed or pulled, allowing flexibility in drive location. 801/265-1000; www.westech-inc.com.
