SCRAPER BRIDGE Sludge Settling
2Pages

EUROPELEC ■ Equipment for primary and secondary settling tanks in municipal or industrial wastewater treatment plants ■ Fully aluminium and stainless steel scraper bridge for higher durability (compared to galvanized steel solutions in particular) ■ Robust and reliable solution ■ Several hundred scraper bridges installed for 35 years all over the world COMPONENTS 1 Aluminium gangway and guardrail 2 Aluminium structural beams — Stainless steel v-notched weir blade. Assures uniform laminar flow throughout the clarifer 4 Stainless steel scum baffle. Prevents matter from reaching the effluent launder — Stainless steel skimmer arm for directing floating matter to the scum box 6 Stainless steel scum box for evacuating floating matter Gear motor and wheel, allowing the rotation of the whole unit, located at the end of the deck in a base which also serves as a support for some of the options Non-driving support wheel which ensures the stability of the gangway during rolling Ring collector for power supply of bridge components 10 Articulated central pivot Stainless steel Clifford feed well enhancing 11 the settling of the sludge at the arrival point of the effluent Stainless steel and EPDM bottom scrapers 12 - they push the sludge towards the central collector where it is gravity drained (or pumped)
