Abstract

The sections are used for producing a wide range of capacities of decantation tanks from a limited number of moulds. The tanks esp. being employed in the treatment of polluted effluent from industrial processes. The sections are moulded as hollow parallel pipes or cylinders with-open top and bottom ends and two vertical transverse walls, one full-depth of the section and the other smaller. Tank sections can be assembled on top of each and/or on top of a closed base section.
