Counterflow Fine Screen

A special feature of this design is the submersible screen grid which is scraped by several circulating screen rakes. The number of scraper rakes and thus the scraping velocity are variable - thereby guaranteeing also highload scraping. One decisive advantage of the submersible screen grid is that there is no necessity for a separate bypass channel or system.

Furthermore a Counterflow Screen allows to replace and automatise cleaning of manually scraped screen girds in existing emergency bypass channels.

• Bars on screen combs can be replaced individually
• The number of scraper bars and thus the scraping intervals are variable and can be adjusted to suit prevailing circumstances
• No emergency bypass required, as the screen grid is floodable
• Operationally reliable and robust
• Parts which are in contact with waste water are made from stainless steel
• Maintenance-free bearings
• Automation upon request
• Maintenance-free drive unit with geared motor
• Easily accessible chain tensioning devices
• Long service life thanks to well-built, robust engineering and design
• All movable parts come after the screen grid
• Explosion-protected
