Methodology of complex studies of industrial waste water
The article defines the goals and objectives of the audit of wastewater as a first and necessary stage of designing treatment facilities or their reconstruction. For example, one of the plants of PepsiCo soft drinks company, which initiated the need for future design work, step by step through the process of audit of wastewater. The task was complicated by the need to predict the flow and wastewater characteristics in connection with the expansion of production with the installation of additional lines in the future. Based on the comparison of the results of analyzes of average daily and hourly samples for 10 days, and production data for the volume of production and water consumption were calculated key figures water use efficiency and product losses of different production lines. These coefficients were used in the simulation of design flow properties and sewage costs, taking into account expansion. The audit has been calculated optimal model design flow wastewater with exceptions justification of it flows from the water treatment and concentrated liquid waste and its separate collection, recommended economically reasonable wastewater treatment technology for the preparation of technical specifications for the design of water treatment facilities. In parallel, we made recommendations for optimizing water management in the factory and performed benchmarking PepsiCo plants for water use indicators.
