Lamella Plate Clarifier

Total Suspended Solids (TSS) will naturally settle over time due to gravity, but this process can be sped up and improved by having an Inclined Plate. Water flows up the plate at a 60° angle. Gravity will force the solids to settle onto the plate. The particles collect on the plates will become heavier and slide back down the plate to the clarifier cone. This process creates a counter flowing pattern, where the solids are seperated from the liquid into two lanes of traffic. The water flows in the upward bound lane, and the sludge flows in downward lane. This method reduces drag and friction creating a faster settling process than if the solids were to settle naturally.

Flocculants and Coagulants are added to improve the settling time. Coagulants neutralize the negative charge particles allowing them to sink faster. Flocculants allow for the small particles to collect and accumulate. This will make the solids heavier and easier to settle.

Benefits

Save space

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

More reliable

Unique 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 settling

Up 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 cost

No power requirement so has minimal operating costs.
