Catenary Monster
This highly efficient and robust Catenary Monster® screening system is suited for large flows, industrial, municipal and combined sewer system applications where large concentrations of debris are expected. This screen is designed to provide quick removal of large debris in order to protect downstream processes.
Replaceable rakes are bolted to two bands of welded, heat treated steel chains which are driven by sprockets keyed and set screwed to the heavy-duty drive shaft. They pass through the guide track which avoids the necessity of sprockets and bearings in the sewage flow. This results in greatly reduced maintenance and increased system life.
Catenary Monster is available with bar spacings of 1/2” (12mm) and up. Debris is removed at the discharge level and conveyed to the Screenings Washer Monster® for washing, dewatering and compacting. This highly efficient washer-compactor quickly cleans-up the large piles of debris captured by the screen.
During screen operation JWCE’s optional Monster Blind Diagnostic System™ monitors, calculates and displays the percent of screen “blinding”. There are three significant benefits of this patent-pending control system. First, MBDS allows the screens to automatically operate at optimal efficiency. Second, it continuously updates the control room on the screen’s precise performance so upsets (for example heavy grease loading) can be detected and dealt with early on before the problem can grow. And finally, MBDS can inform operations when the cleaning brush or spray nozzles need adjustment. Monster Blind Diagnostic System is always watching the screens so you have less to worry about.
