Water Treatment Plant SETA WATSAN M15 ERU 12 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. Silex filter back washing

Water Treatment Plant SETA WATSAN M15 ERU 13 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 3000h. 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.
