Slant Plate Wastewater Clarifier
When it’s necessary to remove particles from a large volume of water, often the best option is to go with a slant plate wastewater clarifier. M.W. Watermark offers high quality, American-made products that are designed to achieve the ultimate goal of keeping the planet’s water supply safe for generations to come.
The M.W. Watermark Slant Plate Clarifier
Our slant plate wastewater clarifier is one of the most efficient methods available for the removal of solids from process liquid and waste. While there exists a variety of designs for such devices, utilizing inclined plates allows us to pack the widest possible combined plate area into a compact floor space. Plates are placed close together, and settling surfaces are stacked to form a settling area 10 times larger than the total area occupied by the machine.

Does you spec call for a Low Profile Clarifier (LPC) design? We can provide that as well. Just ask!
Within our range of slant plate clarifiers, we offer nine standard-sized models, handling between 5 and 400 GPM, a sludge holding capacity between 17 and 960 gallons, and a plate area of between 16 and 1,680 square feet. That large capacity comes at very little cost in terms of floor space; sizes range from 45″ x 23″ to 170″ x 120″, with heights ranging from 51″ to 147″. The machines feature no moving parts, constructed using 1/4″ steel and dye-pen tested welding. Integral flash mixing and flocculation tanks help to increase efficiency, and the entire structure is sandblasted, primed, and painted to provide maximum chemical resistance. Each device comes equipped with 1/4″ thick removable PVC settling plates, dual sludge outlet flanges, sludge sampling ports, and a large side-access hatch to allow for easy maintenance.

Fluid is fed into the top of the wastewater clarifier (A) and flows under a baffle to the integral flash mixing tank (B). At this point, a flocculating agent may be added with a PolyMark™ polymer blending system, and is blended with the fluid using an optional high-speed mixer. From the flash mixing tank, the fluid flows over a baffle into the integral flocculation tank (C), which may include an optional low-speed mixer. From here, the fluid flows through the feed channel, between the two plate stacks, and down to a sludge chamber, located at the bottom of the structure. Large particles begin to drop out of suspension as the velocity of the fluid decreases.
As the liquid enters the bottom of the plates and flows between settling plates, it maintains a low velocity, laminar flow profile which allows the suspended solids to settle on the lower plate, then flow downward to the sludge holding tank. While the solids are settling along the plate surfaces, the fluid is gradually heading upward through the plate stacks, over the weirs, and into the discharge trough.
Finally, the clarified effluent is discharged through a flanged pipe connection. Through sample ports, operators are able to judge the sludge level, which is periodically pumped into a batch storage tank for further liquid-solid separation via an M.W. Watermark Filter Press and eventual disposal.
