Technical re-equipment of the wastewater treatment unit by applying the complex technology of membrane water treatment by reverse osmosis

Equipment used, specifics of works provided

1. The object of automation is the technological process of removing salts from the water recycling system of the enterprise by membrane water purification using reverse osmosis.
2. The product of the complex is desalinated water of a given quality.
3. The total capacity of the complex is 120 m³/h, with two lines of 60 m³/h each, with the possibility of a complete shutdown of one of the lines, including all the necessary stages of preliminary treatment of wastewater before it is fed to the membrane treatment unit, buffer tanks and provides for the possibility of operation at low ambient temperatures.
4. The technology uses chemicals supplied to the system through dosing stations.
5. The chemical composition of the water is monitored by appropriate control devices at different parts of the system.
6. The automated control system of the integrated technology of membrane water purification by reverse osmosis is implemented using Siemens S7-300 series control equipment and ET200M distributed peripherals.
7. Visual control over the process operation and its regulation is carried out from the operator’s automated workstation (AWS) with SCADA or touch panel.
8. The pumps are equipped with automatic frequency control using Schneider Electric frequency converters.
