CDL – Grit Washers
The Fluiteco CDL range is a high-performance solution designed for the intensive washing and separation of grit in wastewater treatment. These units do more than just extract sand; they are engineered to strip away organic pollutants, delivering a clean final product that significantly slashes waste management and disposal costs. Built around a specialized conical decantation hopper, the CDL integrates a dedicated stirring system and a central screw conveyor, a combination that ensures efficient solids extraction, superior organic separation, and long-term mechanical reliability.
Advanced Separation and Fluidized Bed Technology
Efficiency starts with a sophisticated hydraulic process: wastewater enters the unit from the top under a constant head (submerged inlet), while the central agitator creates a controlled vortex. This movement promotes the rapid sedimentation of sand particles while keeping lighter organic materials in suspension. At the base of the hopper, a counterflow of clean water creates a “fluidized bed” that deep-cleans the grit as it descends. This technology achieves an impressive capture rate of over 95% for particles down to 0.2 mm, resulting in high-quality grit with less than 3% organic content and under 10% residual moisture.
Operational Savings and Fluiteco Reliability
Investing in a CDL Grit Washer is a strategic move. By drastically reducing the weight and volume of extracted material compared to traditional classifiers, it often pays for itself through disposal savings within just three to five years. Reliability is baked into the design: the auger is directly coupled to the motor via a flanged shaft to minimize wear, and a standard pressure sensor provides real-time monitoring and precise control over the entire operation.
The Advantages of Fluiteco Design
What sets the CDL apart is its rugged durability and extreme flexibility. To handle highly abrasive materials, we use extra-thick, wear-resistant screws and interchangeable liners in HDPE, Hardox, or Stainless Steel. Maintenance is straightforward thanks to well-placed inspection hatches. For specialized environments, we offer gas-proof versions for odor control, heat tracing for cold climates, and high-grade materials like Duplex or Super Duplex to meet the toughest industrial demands.
