Abstract

A steel mill in southern Illinois near St. Louis, Mo., has constructed $3,000,000 worth of wastewater collection and treatment facilities. These consist of sewers and lagoons formed by building levees in a natural lake. Solids and oily wastes were the most serious effluent problems. Oil-skimming ponds are included in the facilities. Detention time in the lagoons is 10 days for the blast furnace wastewater and 3.5 days for wastewater from other processes. Lagoon effluent is, in most respects, at least as good in quality as the plant water supply drawn from the nearby Mississippi River.
