EFFECTIVE TREATMENT OF GLASS MANUFACTURING PROCESS WASTEWATER WITH CONFORMED EFFLUENT DISCHARGES

Abstract

The constituents of wastewater and effluent discharges from the manufacturing operations was investigated as a representative of other soda lime silica glass manufacturing and other related processes in Nigeria. Samples were sourced from the Forming end, compressor, generator and furnace cooling waters. The samples collected were analysed in the laboratory by physicochemical analysis and Microbiological analysis. The results indicated that the physiochemical parameters such as odourless and clearer colour were observed from the influent. The pH was brought down from 9.0 to 7.8 with the heavy metal kept below maximum limit. The major contaminants in glass waste water are suspended solids which comes from both silica sand and cullet treatment plants, it was reduced from 50mg/L to 30mg/L. The organics and its derivatives have been treated to have moved conductivity from 64 to 100 However, the bacteriological related cocntaminants were eliminated
