Conventional Lime Soda Ash Softening vs Split Treatment at ...

Abstract. In its 1970 expansion, Owosso adopted conventional lime–soda-ash softening followed by recarbonation. The result: maintenance problems arose with sludge deposits in the recarbonation basin and the filter-influent piping with substantial loss in filter efficiency index. In 1973 operation was changed from conventional to split treatment.
