Inclined plate settlers Compact thickening and clarification, reduced retention time

Inclined plate settlers 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 minimized by matching the thickening and clarifying requirements more closely. The two basic criteria for gravity settling equipment are good clarity of the over flow liquid and maximum density of the underflow solids discharge. The area required to clarify a suspension is often greater than that needed for thickening. This means that in a cylindrical thickening tank, the lower section...

Overflow launders Rake lift (optional) Overflow outlet Flocculation agitator Feed inlet Flocculation agitator Lamella plate pack Sludge hopper Rake with drive unit Underflow outlet Inclined Plate Settler The Inclined Plate Settler (IPS) consists of two main components, the upper tank containing the lamella plates inclined at 55° and the lower conical or cylindrical sludge tank. The feed for the IPS enters through vertical chambers on either side of the lamella packs and passes into each plate gap through slot- ted feed ports. Clarification takes place above the suspension inlet so there is no...

Lower installation costs • Heavy duty construction of tank, sludge • Delivered as one-piece unit or in prefabri- hopper and lamella plate packs, as well as the rake system. Rake lifting mechanism as option • Positioning of specifically designed feed ports for optimum ratio between clarification and thickening area • Wide spacing of lamella plates to handle high density feed pulps and coarse solid particles • No short circuiting or surface turbulence • Integrated flocculator with variable speed stirrer cated sections • Smaller foundations • Easily insulated against heat loss or toxic fume emissions...

Model LT The LT model is designed for total projected settling areas of 15 to 500m2 and is suitable for the following applications: • Small to medium solids flow rate • Slurries containing coarse fractions Options: • Extended sludge hopper • Flocculator with variable drive stirrer • Automatic rake lifting device • Automatic underflow control Model LTS The LTS model combines a circular sludge tank and rake mechanism with the clarification capability of the LT lamella plate pack system in a single compact unit. The rakes, together with the larger sludge tank, give: • Increased sludge thickening...

The LTC model consists of a number of lamella plate packs installed in a conventional cylindrical thickener tank with a standard centre-drive rake mechanism to remove the thickened sludge. For higher thickening rates and greater sludge buffer capacity, Metso now offer a specially modified system. The compact prefabricated lamella packs of the LTC design allows the use of very large clarification areas installed in a fraction of the floor area required for a conventional thickener without lamella packs. The LTC system allows a substantial reduction in the overall investment cost. In some applications,...
