STUDIES ON CHARACTERISTICS OF A DAIRY EFFLUENTS OR WASTE WATER

CIVIL ENGINEERING

Identification of Dairy Industry as it’s the most polluting food industry in terms of large amount of water use and also dairy industry have shown tremendous growth in recent years across the world. Characteristics of waste water like Physical- turbidity, color, odor. Chemical - chemical oxygen demand, nitrogen, ph. Biological - microbial, oxygen required for nitrification, Bod. Studies on the performance of effluent treatment by collecting samples. Studies on improvement of treatment or the modification of treatment by low or economical or low-cost methods. Industrial waste management is nowadays one of the main issues for ensuring a sustainable environment. Dairy waste management in particular, is very crucial in view of the high organic matter and high nutrient levels contained in dairy effluents. Dairy waste can be effectively treated either with aerobic or anaerobic processes. The main advantages of the former consist of low yield, high kinetics, pathogen free product, and high temperature operation whereas the latter is a simple, low budget and conservative technology. Occasionally, pre-treatment strategies (i.e. wetlands) are required in order to improve the efficiency of treatment methodology. Wetlands are a promising technology applied in order to remove the greater part of nutrients and minerals contained in milk-based products.
