  1. Underwater cleaning technology

  2. WEDA – since 1919 • Company founded in 1919 • ISO9001:2000 certified production • WEDA subsidiaries in Germany and US • Distributors and agents in 25 countries • Reservoir cleaning serviceoffered on 5 continents

  3. Products Pool cleaners B600 B450 B680 B480 W50 Reservoircleaners VR-600CS-600YT-800 Sludge collectors SD System

  4. Sludge collection in sedimentation tanks WEDA SD System

  5. Sludge collection in sedimentation tanks • Fixed installation with submersible pumps • No basin draining or reservoir downtime • Programmable frequency and speed of cleaning • For optimization of cleaning results/discharged water • Rapid installation – 2 days – minimizes tank downtime • Robust and reliable components - little maintenance WEDA SD system SD system

  6. Sludge collection in sedimentation tanks Specifications Dimensions Pump capacity Main voltage Discharge Speed Dimensions are customized to your facility needs Standard system widths from 5’ (2m) to 33’ (10m) Custom configured to your facility needs 400V, 3-phase 3” hose Infinitely variable from 0 to 10ft (3m)/min SD system
