Metso's lamella principle uses several parallel inclined plates to maximise the available area for any available floor area. In this way, the size and cost of the gravity settler can be minimised by matching the thickening and clarifying requirements more closely.The ...
Function
The sludge is fed through a central influent cylinder mounted to the thickener mechanism into the thickener tank.
The thickening process is intensified with the application of vertically mounted stirring members. By means of an echelon type scraper blade assembly the thickened sludge on the tank bottom is removed to a center hopper from where it is drawn off ...
Thickening increases the solids content of material by reducing the liquid ...
The Graver Rota-Rake® is a horizontal flow sedimentation and thickening unit for the efficient separation of suspended solids and is designed to provide maximum separation, positive sludge removal and full overload protection.
In the Rota-Rake the water enters a central inlet well where its velocity is reduced. The large laminar flow achieved ...
