A unique patented design that features multigrade filtration to remove suspended solid contaminants. For use in water and waste water treatment. The VOLCANO SAND FILTER is a continuously backwashing filter which eliminates the need to shut down for backwash like conventional sand filters. Feed water containing contaminants flows downward through coarse, intermediate, and fine sand-media. The contaminants are captured, and the purified water leaves the filter as filtrate. The air lift transports the contaminated sand to the top of the filter where it is cleaned in the washbox. The contaminants are then removed via the reject stream. The cleaned sand falls back to the sand bed and classifies into coarse, intermediate and fine media layers. The process is continuous.

Settling area is the most important design factor in a clarification system. A Plate Clarifier contains a series of inclined parallel clarifier plates. The settling area of a Plate Calrifier is the total of the areas projected on the horizontal plane by the clarifier plates. The overlap of the pararell plates concentrates the effective settling area into a compact space resulting in substantial space savings over conventional circular clarifiers. Loading rates used in design of the PC™ Plate Clarifier are equivalent to those used for conventional clarification.
