Waste Water Treatment Peripheral Traction Clarifiers with Sludge Suction PTA DS.PTA.EN.October 2015.R00 Rights reserved to modify technical specifications. Description ▼ Peripheral Traction Clarifiers PTA are used to suck biological sludge and remove floating particles in circular primary and secondary settlement tanks in both municipal and industrial purification plants. This equipment is composed of a movable truck lying in the centre on a rotating central support and at its periphery on a traction trolley. The clarifier is operated by a gear motor connected to a slip ring placed in the central support. Waste water enters the concrete tank by means of a central cylinder, which spreads the liquid. Sludge settles on the tank bottom, while light particles and scum float. Thanks to the slow truck movement, special syphon pipes equipped with scraper blades suck the settled sludge. The syphon pipes are adjusted by means of telescopic valves installed on the walkway. Floating particles are collected by the surface scraper and conveyed into the scum-box. Clean water flows into the peripheral launder through the Thomson profile weirs. Application Benefits 3 Quick installation; 3 High removal efficiency of sludge and floating material; 3 Easy installation also for existing tanks. www.savi-water.com www.wamgroup.com
