Rotary Drum Screen

Product Character

Rotary drum screens are pre-treatment or primary treatment units in wastewater treatment systems, commonly used for the initial filtration of sewage, wastewater, and sludge. They are particularly suitable for treating liquids containing high levels of suspended solids and fine residues, thereby reducing the load on subsequent treatment units.

  • Product Advantages
  1. Continuous Filtration for Maximum Throughput: Adopting a continuous filtration design, the system is capable of uninterruptedly processing large volumes of wastewater. Coupled with a highly efficient residue discharge mechanism, stable and high-volume flow is maintained even when treating liquids with high solid content. This ensures the system's maximum wastewater throughput, effectively meeting high-load treatment demands.
  2. Reversible Backwash Screen to Sustain High Efficiency: The unique reversible backwash screen design allows for backwashing to occur without interrupting the main filtration process, quickly clearing screen blockages and restoring filtration performance. This guarantees long-term high-efficiency operation, minimizes manual intervention, and reduces maintenance costs.
  3. Efficient Removal of Fine Solids to Promote Water Recovery: The fine screen effectively intercepts suspended solids and fine contaminants from the wastewater, protecting downstream equipment and creating conditions for water resource recovery and reuse. This reduces fresh water consumption, aligning with the concept of green production.
