  • Field assembled clarifier
    Patent number: 4476018
    Abstract: Large settling tanks or clarifiers of the travelling bridge type are provided in easily assembled small component sections fitting a conventional size flat bed truck for shipment to a use site to be assembled on a concrete basin requiring only a lifting crane and a small assembly crew. The knocked down clarifier eliminates heretofore required on-site time consuming building by skilled personnel and makes possible factory prefabrication of all of the clarifier parts with the exception of the concrete basin.
