Lamella Plate Clarifier

hydro-int.com

Remove sediment from wastewater and industrial water reliably and effectively, using up to 80% less footprint than conventional technologies.

Applications

The Lamella Plate Clarifier is a primary clarification device used to treat sewage and industrial waste streams and requires up to 80% less space when compared to a traditional settling tank.

Supplied as a complete, easy-to-install unit or as a plate pack assembly for installation into either a concrete or steel tank, the Lamella Plate Clarifier provides low-footprint water clarification for municipal and industrial treatment applications. By reducing the settling distance dramatically, higher flows can be treated in a much smaller footprint.

• Primary clarification of wastewater.• Wash water recirculation systems (such as potato

and root crop processing).• Raw water clarification.• Wash water settlement.• Humus settlement.• Wet scrubber and slaking effluents in the power

industry.• Thickening processes in the chemical, mining and

mineral industries.• Treatment of effluents in metal finishing, and iron and

steel plants.

Example Removal Performance

BenefitsSave spaceSpace requirement can be reduced by up to 80% when compared with a settlement tanks.

More reliableUnique patented flow control system increases reliability. The use of plates with side entry rather than tubes increases capacity and prevents the sludge being disturbed.

More settlingUp to 10 m2 of settling area per square metre of ground area.

Optional configuration Available as a free-standing unit or supplied as plate packs for installation into concrete or steel tanks. Plates can be supplied with variable spacings of 50, 60, 80 and 100 mm to suit the sludge characteristics.

Low costNo power requirement so has minimal operating costs.

Application Removals

Product Information• LS Plate Separator - the system includes a conical

sludge hopper and can be equipped with a sludge discharge scraper. A flocculation tank with stirrer can be added to the system to allow chemical dosing and flocculation time prior to settlement.

• LT Plate Separator - a combined separator and sludge thickening unit designed for liquids with high sludge contents. A flocculation tank with stirrer can be added to the system to allow chemical dosing and flocculation time prior to settlement.

• LP Plate Pack Assembly - for installation into a concrete tank. This option can also be installed in an existing tank to increase its capacity.

1. Effluent enters the unit through the inlet pipe (brown arrow) and flows downward through the inlet chamber in the centre of the unit, entering the plates through openings in the sides.

2. As the liquid flows upward the solids settle on the inclined, parallel plates and slide into the hopper at the bottom of the unit. In the hopper, the sludge is thickened prior to discharge through the sludge outlet (brown arrow).

3. The clarified liquid leaves the plate assembly through openings at the top and is discharged into collection channels leading to the clarified water outlet (blue arrow).

4. The openings at the top of the plate assembly are designed to create a pressure drop across the collection channels, ensuring that the flow is distributed uniformly between the plates and that the full area is utilised. This is a patented flow control feature.
