Our mobile clarifiers compact unit, make this Lamella® clarifier unique to ensure maximum, balanced utilization of the inclined plate area.

Mobile Lamellas to Buy or RentSince 1989, Sepratech has offered a mobile LAMELLA ® Gravity Settler* that is a pre-assembled, modular, that has a high rate inclined plate settler using a counter-current flow principle for effective solids removal. Call Sepratech to schedule an installation of this mobile unit, as well as maintenance.

The inclined plate concept provides an effective settling area that is equal to the area of each plate as projected onto a horizontal surface. Using the standard 2″ plate spacing and 55° angle, up to 10 ft² of projected area become available for each square foot of land area.

In the LAMELLA® Gravity Settler, influent enters the unit and is distributed onto the plates through side-entry inlet slots. The side-entry design, unlike less efficient bottom feed designs, reduces the risk of disturbing previously settled solids and offers better effluent quality at higher plate loading rates.

As the liquid flows upward, the solids settle on the inclined, parallel plates and slide into the sludge hopper at the bottom. Further thickening of the sludge is achieved in the hopper due to compaction in the quiescent zone beneath the plates. The clarified liquid leaves the plate assembly through submerged orifices or weirs at the top of each plate and is collected in channels leading to the clarified water outlet. This creates a pressure drop across the collection channels, which ensures uniform flow distribution across the plates in order to utilize the full area for settling.

Where a more concentrated sludge is desired, the LAMELLA® Gravity Settler/Thickener is the solution. The LGST is a high-rate gravity settler combined with a circular picket-fence sludge thickener/scraper in one tank.

For larger applications, LAMELLA® Gravity Settler plate packs are installed in concrete tanks to increase the performance of new or existing facilities. Plate packs can be combined with a Parkson sludge scraper or vacuum sludge removal system for even greater efficiency.

For potable water, the LAMELLA® Gravity Settler produces effluents less than 1 NTU. Components are classified by Underwriters Laboratories, Inc. in accordance with ANSI Standard NSF-61.

LGS and LGST systems offer reliable liquid/solid separation for potable and municipal wastewater treatment plants, chemical industries, metal finishing, metallurgical industries, pulp and paper mills, power plants and industrial process makeup water applications.
