Rotating bridges (for sedimentation tanks)


Sedimentation systems are of big use in the field of wastewater treatment. Scrapping bridges are used to collect the sludge from the bottom of the sedimentation tanks. These constructions can be either circular or rectangular and are of crucial importance in a wastewater treatment plant.

The scraping mechanism for the circular sedimentation tanks, consists of a bridge that rotates at a very slow rate, powered by a drive unit which is located in the center of the tank. The rotating bridge holds the scrapper just above the bottom of the tank where all the sludge is collected. The sludge scrapper, guides the sludge towards a collector hopper which is located in the center on the tank.

Construction material of the bridge

Stainless steel 304 or 316

Type

R: Radial construction

D: Diametrical construction

Length

Type R

From 4 up to 12 m

Type D

From 12 up to 30 m

Scrapper

Made from stainless steel, formed and adapted to the needs of each specific application.

* The Scrapper systems are adapted to the needs of each specific plant that are about to operate each time. The construction routine follows specific standards but the dimensions from one construction to one other may vary significantly, according to the fields of use.
