OWALamella - Sedimentation unit

OwaLamella is a solution built in a sea container, available in two different sizes: 20 and 40 feet containers. The sedimentation unit separates solids from the liquid by using gravity instead of flotation. Flocculants can be used to improve solid-liquid separation by collecting smaller particles into settleable flocs.

The sedimentation unit enables the effective separation of solids when the impurities in the treated water are not suitable for a flotation-based method.

The flow capacity of an individual unit is approx. 50 – 400 m3/h, which can be increased by adding more units side by side. The quality of the treated water always determines the final maximum capacity.

Examples by industries:

  • Mining Industry – process and mine waters
  • Mining Industry – valuable side streams
  • Constraction Industry – soil conteining waters
