Water supply to chemical enterprises is one of the most important tasks of modern industry. Water is widely used in industrial production processes. Quality and cost value of the final product, as well as the service life of the equipment and industrial safety level, depend on the efficiency of water management systems. The water management system of the enterprise includes a significant number of local systems that ensure the functioning of individual production systems (subsystems) and in general case, have different requirements to water. It should be noted that for the operation of a local system, several others may be involved. For example, technically prepared or demineralized water can be used for distillation; cooling is carried out with circulating water; heating – with water vapour and the drainage can enter either the system of water treatment or the sewage collection system.
