2-9.6.1 Cleaning. Equipment should be cleaned for general housekeeping as well as
for maintaining it in proper operating conditions.
2-9.6.1.1 Filter Plates and Filter Media Cleaning. Cleaning of filter plates and filter
media is an important aspect of maintaining filter press performance, as well as pre-
venting damage to equipment. During the filter cycle, sludge particles remain on the
filter media owing to repeated use or because of poor cake release and eventually
become imbedded in the cloth, causing blinding. Blinding results in poorer sludge cake
quality and longer cycle times because a less effective area is available for filtrate to
exit. Blinding can also result in plate damage from deflection caused by unequal filter
cake formation and unequal pressure distribution.
