WATSAN M 15 ERU Silex filter back washing The purpose of back washing is to force water to circulates in the opposite direction of the normal flow inside the filter. This will cause washing away all the retained particles result of the working load of the filter. It is advisable to back wash when the difference between input and output manometers is more than 0. 7 bars. Water Treatment Plant SETA 12

WATSAN M 15 ERU Active carbon filter back washing The active carbon filter does not regenarate through back washing but there is a settlement process of the particles. It is necessary to substitute the active carbon every 3000 h. hours depending on the working conditions. • • • Slowly open the back washing valvas to avoid lost of material. Back washing waste water is highly contaminated and must be drained in safe conditions. The frequency and length of the process will depend on the quality of the raw water.
