Main equipment for the removal of settled sludge at waste water treatment plants.

Properties

• Peripheral driven
• Tailor-made production
• Easy handling and fast assembling
• Easy operation
• Long life

For the settling tanks having 6 to 48 m. diameter, the rotating bridge scrapers consists of motor-reducer, central bearing, bridge, scraper arms and blades.

Mounted to the central concrete structure, the bridge is being fabricated in standart profile construction in onder to resist static and dynamic loads.

The sludge is scraped through the sludge cone by rotational movement with a peripheral speed changing from 2 to 4 cm./sec. Polyamid wheels, caoutchouc scrapers under the sludge scraper and swing joint of the arms ensure the smooth rotational movement of bridge. Motor-reducer sytem is protected for weather conditions.

The whole parts of the scraper are being fabricated in epoxy coated carbon steel to prevent corrosion. However it can be manufactured in stainless steel upon request. Walk way grid of the bridge is produced from galvanized steel.
