Measurements of physical-chemical characteristics of dairy plant waste waters

Abstract

Characteristics of waste waters of the dairy industry are specific and differ essentially from waste waters of other branches of the food industry. The complexity of production in dairy plants with several units for different products render the problem of waste waters of this industry particularly complex. Waste waters of the AD Imlek dairy plant were sampled and their chemical characteristics were determined at different seasons of the year and at different times of the day in the years 2001 and 2007. The obtained concentrations were compared with the maximum permitted concentrations listed under the Regulations on technical and sanitary conditions for releasing waste waters into the City Sewers of the City of Belgrade.
