Description
PTP Peripheral Traction Clarifiers are used to remove biological sludge and floating particles in circular primary and secondary settlement tanks in both municipal and industrial waste water treatment plants.
Function
PTP Peripheral Traction Clarifiers consist of a movable truck lying in the centre on a rotating central support and, at their periphery, on a traction trolley. PTP Clarifiers are operated by a gearbox connected to a slip ring placed in the central support.
Waste water enters the concrete tank through a central cylinder which spreads the liquid. Sludge settles on the tank bottom while light particles and scum float to the surface. The slowly moving truck makes the logarithmically shaped bottom scrapers convey the settled sludge into the central sum pit. Floating particles are collected by a surface scraper and conveyed into a scum-box.
Clean water flows into the peripheral launder through Thomson profile weirs.
