Acme Engineering’s automatic scraper strainers are designed to flexibly and reliably tolerate surprises while meeting water treatment requirements. The company’s motorized unit is designed to continually remove both very large and very small suspended solids from waste­water. Cleaning is accomplished by a spring-loaded blade and brush system, managed by a fully automatic control system. Four scraper brushes rotate at 8 RPM, resulting in a cleaning rate of 32 strokes per minute. The scraper brushes get into wedge-wire slots and dislodge resistant particulates and solids. This approach enables the scraper strainers to resist clogging and fouling when faced with large solids and high solids concentration. It ensures a complete cleaning and is very effective against organic matter “biofouling.”
