Abstract
Increasing world population, reduction of water per capita, industry development and reducing renewable water resources has caused human society to pay attention to the issue of water consumption management and its optimal use. According to the location of Iran, lack of atmospheric precipitation, lack of proper weighing of these rains and its temporal and spatial distribution have caused it to be included in the category of semi-arid and arid countries of the world. In this article, considering the water crisis and the social duty of environmental protection the technical and economic plan the recycling of the effluent from the treatment plant of a dairy product manufacturing company has been investigated, and due to the relatively large organic load of the effluents of dairy companies, biological methods are usually used for its treatment. In the end, wastewater with standard environmental conditions is obtained for discharge to surface water, and then advanced treatment is performed to obtain clean water. The output water resulting from the advanced treatment of dairy waste can be optimally used in all parts of the factory. According to the technical issues and taking into account factors such as fixed and variable costs, the capacity of the outgoing sewage, the cost of buying clean water, etc., the implementation of the plan is completely economical.
