What Is a Slant Plate Clarifier?

A slant plate clarifier is used in industrial water treatment applications to provide low cost, yet extremely efficient solids removal from a wide range of waste and process liquids.

The key advantage of slant plate clarifiers over conventional types of clarifiers is the use of a series of inclined plates. These plates are able to provide a large settling area for particles and allow for a more compact footprint, greatly reducing the floor space needed for accomplishing the same result.

In fact, this inclined plate design allows the settling area, or surface area, to be as much as 10 times more than the actual floor space occupied by the clarifier. This significant reduction of the required floor space is achieved by reducing separation between plates to just two inches, and stacking the settling surfaces at an angle. The bottom line advantage to the slant plate design is getting the maximum square footage out of your production floor space, which translates into greater efficiencies and cost savings for your operation. Because the slant plate clarifier uses inclined plates, it is often referred to as an “inclined plate clarifier.” A slant plate clarifier is also referred to as an “SPC.”

The reduced required footprint of an SPC provides the opportunity for the clarifier to be located indoors, which allows for better control of ambient conditions. The use of inclined plates also allows the SPC clarifier to operate with flow rates 2 to 5 times that of horizontal clarifiers in a given footprint.

Another advantage worth noting is the SPC’s general absence of moving parts. In many cases, the only mechanical component is the influent pump, which translates into less chance for mechanical failure, a safer environment, and cost savings in energy consumption over traditional clarifiers.
