At GN Separation, we specialize in providing high-quality equipment for liquid and solids separation across various industries. One of our key products is the Slant Plate Clarifier, also known as the Inclined Plate Clarifier, a highly efficient and cost-effective solution for clarifying liquids by separating suspended solids.

What is a Slant Plate Clarifier?

A Slant Plate Clarifier is a gravity-based liquid-solid separation equipment designed to remove particles from liquid streams. When a mixture of solids and liquids (which may or may not be flocculated) enters the clarifier’s inlet trough, it flows upward through a series of inclined plates. The solids in the mixture settle on the plate surfaces, sliding down by gravity into a sludge collection hopper. The clarified liquid then flows through orifice holes and exits at the top of the clarifier.

Advantages Over Traditional Systems

Compared to conventional settling tanks, the Slant Plate Clarifier offers several distinct advantages:

• Smaller Footprint: The inclined plates increase the effective settling area, allowing for efficient solids separation in a compact space.
• Cost-Effective: It offers a more affordable solution than traditional settling tanks, with a significantly smaller footprint for the same processing capacity.
• Energy Efficient: The Slant Plate Clarifier operates using gravity, requiring minimal power for the separation process compared to more energy-intensive systems like decanter centrifuges.
• Low Maintenance: With fewer moving parts, especially in comparison to decanter centrifuges, the Slant Plate Clarifier is easy to maintain. The only mechanical component that may require attention is the auger that helps transfer sludge.
