Water purification in the process industry

The need for water is constantly growing, and the use of this natural resource is still not ta-ken seriously. In modern production systems, water must be of a certain quality to meet the requi-rements of its specific application. However, in recent times, there has been a growing realization that freshwater resources are finite, prompting the search for solutions that will enable reuse, thereby alleviating to some extent the problems of scarcity, cost and regulation. The use of water in industry takes a significant share of the world's water consumption, which is why this area should be given special attention. Reducing the amount of water used in various industrial branches and technical-technological processes will lead to less extraction from local water sour-ces, increased productivity, reduced discharge of waste water and its polluting impact, as well as heat energy consumption and operating costs. The reuse of wastewater in industry can be realized within one or more companies, guaranteeing them savings on water bills and treatment costs. De-pending on the pollutants they contain and the intended reuse, wastewater can either be used di-rectly or first treated and recycled. Process control is extremely important for any water tre-atment. In most cases, programmable logic controllers analyze all measured signals from the va-rious stages and control the process to ensure successful and accurate purification. Standard communication technologies (most often Profibus or Ethernet) are used to transfer this data. Mo-dern systems include solutions based on a cloud platform and automated remote control.
