What Is Lamella Clarifier

Lamella Clarifier is fitted with a plate pack to maximise the effective settling area of the unit and a conical sludge hopper in a small footprint. Lamella clarifiers are ideal for applications where the solid loading is variable and solid sizing is fine. Lamella Clarifiers are considered to be one of the best options for pre-treatment ahead of more sophisticated treatment technologies because of their ability to remove a significant solids loading. The MAK Water Lamella Clarifier can be integrated into a treatment process or as a stand-alone unit. Typical applications are for separation of grit or metal removal or any other application where the solids have a specific gravity >1.0.

Features Of Lamella Clarifier

• Projected Settling Area

Inclined Plates allow for a compact design, therefore reducing the need for valuable floor space. The plates are angled at 60° allowing for an efficient projected surface area. Larger angles cast a smaller projected surface area, and shallower angles disrupt sludge flow and potentially could clog the plates. In the diagram, the Total Projected Surface Area graphically compares the equivalent floor space needed. One Standard Plate Pack is equivalent to holding tank or a circular thickener.

• Retention Time

Design allows for a 50-60 minute retention time. This is a much better retention time than a traditional Parkson Style Clarifier which has nearly half the retention time. By having a greater retention time, this allows for more settling time, which improves the counter flowing pattern as described above. Moreover, a larger retention time Reduces the Risk to Overrun the Clarifier.

Optional Design Features

• Flash mix/flocculation tanks with mixers
• Full stainless steel construction
• Concrete tank designs for large flows
• Special coatings and plate materials available
• Integral mechanical sludge thickener
• Access platform and ladder
• Gasketed and removable covers
• Automatic desludging
• Instrumentation and controls
• Chemical feed equipment
• Sludge handling and dewatering

Availbailable Designs

• Inclined plate length 1–2 m
• Plate pitches between 50° and 60°
• Allow for self-cleaning, pitches require backwash
• Loading rates are 5 to 15m/h
• Set up scraper for easy drainage.
