Monoblock Vibrated Reinforced Concrete Underground Precast Structure
used in both drinking water and wastewater treatment
Features and Operating Principle
The Dortmund-type settler is used in both drinking water and wastewater treatment; its main feature is having steeply sloped internal walls that form a pyramidal bottom. This inclination allows the sludge to slide and settle at the bottom of the hopper, from where it is then extracted by means of a submersible electric pump. The sewage is fed into the tank through a pipe connected to a submerged deflector; following an upward path, it then flows into the surface weir launder significantly clarified, making it suitable for final discharge or subsequent treatment.
