Abstract

302,446. Handley, A. C. Oct. 15, 1927. Filters with loose filtering-materials.-An opentank filter, intended particularly for the treatment of sewage and trade effluents, is provided with holders A containing coir fibre, arranged in rows extending across or along the tank, sand filter-beds B being provided between two or more of the rows. The holders for the fibre may be formed by sheets of expanded metal bolted together. The sand can be poured into the spaces between the fibre elements or may be charged into openwork containers which are placed in the spaces. The tank is provided with inlet C, outlet D and overflow E.
