Abstract:
1. A method of installing an air scour system in a filter having a filter compartment with at least one vertically extending sidewall, a bottom and a filter bed including at least one layer of filter media, said method comprising the steps of: (a) providing at least one drop pipe, at least one header and a plurality of laterals such that when connected said at least one drop pipe, said at least one header and said plurality of laterals form an air scour system; (b) attaching at least one vertically extending guide member to said at least one vertically extending sidewall of said filter compartment for guiding said air scour system into an operating position in which said air scour system directs air through the filter media; (c) attaching said drop pipe with said at least one vertically extending guide member so that said at one vertically extending guide member guides movement of said drop pipe; (d) connecting said drop pipe, said at least one header and said at least one lateral to form an air scour system where said drop pipe is positioned adjacent said at least one vertically extending sidewall of said filter compartment when said air scour system is located in an installation position; (e) subsequent to step (d), imparting a force to the filter bed to permit at least a portion of said air scour system to be inserted into the at least one layer of filter media without removing media from the at least one layer of filter media; (f) moving said drop pipe relative to said guide member to lower said air scour system into said at least one layer of filter media such that an uppermost portion of said at least one header is positioned below an uppermost portion of said at least one layer of filter media; and, (g) connecting a source of compressed air to said air scour system.
