ABSTRACT |
A medium scale Mung Bean starch factory was taken in this study to assess the pollution caused by various streams in starch and noodle factories, and to provide the basic information for wastewater management in them. This study shows that the wastewater from starch processing unit with 46 — 54 tons production capacity is the main polluting source, contained high values of CODr and SS. Also the specific water consumption to process one ton Mung Bean in 16 — 25 m3 is higher than theoretically required one. Methods have been proposed for minimizing and treating the wastewater produced by the factory to overcome the pollution problems. One of the alternatives is to use water in a controlled way by marking optimum flow rates on the tab valves, in which water consumption can be brought down. However, bio-treatability of wastewater can be used for treating the total wastewater due to the suitability in characteristics. |
