Water & Wastewater SludgeScreen™ Advanced Pressurised In-line Sludge Screen A Superior Screen with Reverse Function Versatility Applications • Designed for either direct tanker, pumped feed or combination. Wastewater Screening • Ship-board preliminary treatment. Sludge Screening • Primary • Secondary • Imported The SludgeScreen™ is an inline pressurised device that screens and dewaters sludge in one operation. The enclosed system reduces odour problems and has no washwater requirements. Advantages • • • • • • • • • • Enclosed system, reducing odour problems. Screening, dewatering and coarse material discharge in one operation. No washwater requirement. Fully automatic for either continuous or intermittent screening of sludges with varying dry solids content. Continuous coarse material separation under pressure with loss of pressure dependent on sludge thickness only. Reverse function in manual mode to allow the retention cone to be backed off without disconnecting the air supply. Manufactured from impact resistant SG Iron to BS 2789 Grade 420/12. Screening section screw manufactured from low carbon steel with stellite tipped flights. Combined testing of control panel and machine before delivery. Machine and control panel connected and fitted to platform prior to despatch to minimise installation time. Drive Inlet Screening Zone Pressing Zone Screenings Outlet Sludge Inlet To Sludge Digester or Clean Sludge Holding Tank Operation 1) Flow enters through the centre of a sludge inlet (red arrow). 2) Sludge passes through the perforation and exits via the sludge outlet (blue arrow), whilst To Container / Skip the screenings are trapped inside. 3) A rotating screw moves the screenings off the inside of the drum to the pressing zone. 4) In the pressing zone the screenings are pressed against a retention cone which is balanced against the drive load of the screw. 5) Dewatered screenings are discharged by gravity via the screenings outlet (brown arrow). turning water around ...® Tel: 01353 645700 • Fax: 01353 645702 • www.hydro-international.biz
