A process has been implemented to measure filter media sedimentation depths monthly using a clear tubing core tool
pictured in attachment the data will be recorded and compared to filter design specifications. Also attached is the
designed filter sedimentation details. Sieve Analysis will be performed on a yearly Basis and recorded and compared to
the filter design specification. The Sieve Analysis is to satisfy ASTM C136 Method. Please feel free to contact me if you
need any further information to correct these deficiencies.
Thank you
