Grit Chambers

Grit removal is a sedimentation process and the chapter could have been included in Chapter 6, but was felt to warrant being dealt with separately in order to focus on grit as a special case.

Not much has been published on grit removal as compared to other unit processes in water treatment. Perhaps the topic has lacked ‘‘glamour,’’ or perhaps therewas notmuch to be said after Camp’s 1942 paper (Camp, 1942), and became an established process (Box 7.1). Ancillary technologies, that is, to make the process work, include scrapers, lift devices, and grit washing.
