Lamella clarifier separates solids from a carrying liquid by directing the material between a series of inclined plates. The plates are normally spaced 10cm apart with the result that large settling surfaces are concentrated. Stacking the inclined plates results in a separator having 5-10 times the clarification area of a conventional settler with the same floor space. In other words, it does the separator job in 1/10th of the space.
The WatMan lamella construction ensures laminar flow conditions, which result in a stable hydraulic flow and high effluent quality. It allows a great reduction in the space needed for clarification equipment, and for easy relocation at a later date. Use of a lamella separator reduces maintenance to a minimum. There are no moving parts and its compactness allows it to be located in new, automated plants or in upgraded existing installations where there is often no space available for a standard clarifier. Installation costs are also significantly reduced. As an option, we can design a clarifier with a sludge scraper. This is an excellent choice where there are hard-to-handle solids, typically in waste water applications.
