LACKEBY ROTO-SIEVE® DRUM SCREEN RS

High-performance drum screen with world-class separation technology

The drum screen with the industry’s most efficient particle separation

Lackeby Roto-Sieve® is a high-performance, self-cleaning drum screen for wastewater treatment, designed to provide the industry’s most efficient particle separation. It is ideal for primary separation, sludge screening, and recycling in various applications.
 
With a durable design and few moving parts, Lackeby Roto-Sieve® has low energy consumption and a long service life. Thanks to its innovative belt drive and design, it is both a cost-effective and reliable investment that pays off over time.

Industrial applications

  • Poultry, meat, and fish processing
  • Fruit and vegetable processing
  • Pulp and paper
  • Beverage (beer, wine, juice, etc.)
  • Dairy
  • Fiberglass
  • Recycling (plastic and metal)
  • Biogas sludge screening

Water and wastewater applications

  • Primary screening
  • Fine screening prior to membranes
  • Septic screening
  • Sludge screening
  • Sludge thickening
  • Reject water screening
  • Fine screening
  • MBR Protection

High performance

  • High degree of separation due to perforated drum and pressureless separation.

  • No need for upstream screening before the drum screen.

  • No sealed openings or internal moving parts that can result in material passing through. The entire flow must pass through perforated holes to reach the downstream process.

  • High capacity and high capture rate with a small footprint.

Low costs

  • The lifetime of screen is normally more than 20 years.

  • Self-cleaning design for low degree of maintenance.

  • Few moving wear parts which are accessable without cranes or any other lifting devices.

  • Low energy consumption.

  • Low spray-water consumption assures substantial savings in water costs compared to competing products.

Design simplicities

  • The lowest number of moving parts of any drum screen on the market today.

  • The advanced carbon fiber polychain drive system eliminates the need for trunnion wheels. This significantly lowers required maintenance and improves reliability.

  • No chains of any kind results in less maintenance issues. No need for automatic oilers.

  • Easy access for full visual inspection thanks to lightweight fiberglass covers.
