Optimized Product Introduction: XLC Series Vortex Grit Chamber for
Municipal Wastewater Treatment
Application
The XLC Vortex Grit Chamber utilizes a hydrocyclone mechanism to
effectively separate silt, sand, and organic matter from
wastewater. It is widely applied in pre-treatment processes across
municipal sewage treatment plants, industrial facilities, mining
operations, and institutional water treatment systems.

Structure and Working Principle
The cyclone grit chamber features a conical-bottom circular tank
equipped with a rotating paddle separator. Wastewater enters
tangentially and follows a 270-degree rotational path (clockwise
from top view) before exiting through the discharge channel.
The tangential inflow creates a swirling motion along the inner
wall, enhanced by the paddle agitation. This generates an axial
vortex that accelerates the settling of sand particles while
effectively separating organic matter. The flow velocity increases
toward the center, guiding settled sand in a spiral trajectory to
the central hopper. Organic materials rise centrally and are
discharged with the effluent. Sand collected at the bottom is
extracted via a lifting mechanism (airlift or pump) and directed to
a sand-water separator, with separated wastewater returning to the
screen channel.
Key Features
Stable Performance: Consistent desanding efficiency despite flow variations. Compact
design with easy operation and maintenance.
Flexible Sand Extraction: Optional airlift (better treatment effect) or pump lift (lower
cost).
High Efficiency: Removes >85% of particles ≥0.2mm.
Material Options: Steel construction for Q <1080 m³/h; concrete structure for
higher capacities.
Automated Control: PLC-controlled sand washing and discharge cycles for reliable
operation.
Ease of Operation: Local and remote control capabilities for user convenience.
