EnviroHub Lamella Tank (HL)
The HL series comprises of lamella settlement tanks, effective settlement areas being denoted by their numerical code. The HL-R series meanwhile comprises of lamella settlement tanks with motorized rakes. Again, effective settlement areas are denoted by their numerical code.
Overview
Settlement tanks are used to remove heavy suspended solids from a process fluid. Lamella settlement tanks use an array of inclined plates to vastly increase the space efficiency of a settlement tank. In the case of the HL-R series, the addition of a rake maintains liquefaction of sludge.
Most HL and HL-R units are equipped with an oil skimmer that can be used to remove a small to medium quantity of light hydrocarbons and light particles from process fluid.
Typical Applications: Silt laden surface water clean-up for safe discharge,Excavation dewatering,Tank, lagoon or lake dewatering,Surface water drainage clean-up,Wash down or blast water solids settlement
Features & Benefits
Features:
- Discharge ports for sludge and water
