WEDA SD system
 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
