| Includes | sludge removal and skimming removal equipment, and other equipment usually associated with circular or rectangular clarifiers and sedimentation tanks, for water treatment and wastewater treatment. Sludge collection equipment and systems not typically associated with traditional clarifiers, sedimentation tanks, or retention tanks; includes dissolved air flotation equipment used in water treatment. Circular clarifier equipment may include cage drive, shaft drive, or rim drive types; sludge collection using segmented plows, spiral rake, suction pipes, or suction header; center-feed or peripheral-feed equipment, flocculating clarifier variations, and various types of scum removal equipment. |
| Notes | tanks associated with clarifier equipment are typically under the Division of the associated tank material or work result (such as Division 03, Concrete), or in 43 41 00, Atmospheric Tanks and Vessels, or any other appropriate Division. |
