Sewage Treatment plants with Messung’s NX-ERA Xpress Series

Sewage is the waste generated from residential, institutional, commercial and industrial establishments. Due to the hazardous impacts of municipal, industrial and hospital wastewater on water, soil, air and agricultural products, wastewater treatment and the proper disposal of the sludge produced are indispensable from an environmental safety point of view.

Moreover, due to the global water shortage crisis, water from wastewater treatment needs to be reused increasingly in the near future. Reuse of sewage is the most sustainable and long-term solution to the problem of water scarcity.

Sewage Treatment Plants (STP) treat the sewage and waste water to produce a cleaner, more environmentally friendly effluent that is safe for disposal, gardening/agricultural use or domestic use in toilets, etc.

Physical, chemical, and biological processes are used to remove contaminants and produce treated wastewater (or treated effluent) that is safer for discharge into the environment or for reuse.

APPLICATIONS WHERE SEWAGE TREATMENT PLANTS ARE USED

A great example of STP is the treatment plant you find in big cities. Residential households, commercial buildings, municipal wastewater, etc. also use STPs to treat their waste water and sewage. In fact, STPs are mandated by government and municipal authorities.

THE CUSTOMER

Our customer is a one-stop solution provider in industrial water treatment plants. They deliver complete water treatment solutions through a rational blend of technology & human capital. They not only manufacture industrial water treatment plants but also supply water treatment chemicals / spares. This company is a growing enterprise as a manufacturer of water treatment plants and supplier of water treatment chemicals providing all the services associated with it.

KEY FEATURES OF THE SEWAGE TREATMENT PLANTS

  • Rids potential diseases. Wastewater treatment systems eliminate disease-causing bacteria and kills harmful organisms
  • Minimal odour emissions
  • No water bills
  • Little maintenance
  • Break down solids faster
  • Less wasteful
  • Low-cost for the entire process

THE SOLUTION

Messung engineers studied the process and its requirements, and came up with a solution consisting of

  • NX-ERA XPRESS XP300 PLC controller
  • XMPRO REMOTE CANOPEN IO Modules
  • 7 inches HMI

The proposed automation solution for Sewage treatment plant involves the use of a series of small control systems that run the facility ;a PLC (Programmable Logic Controller) to continuously monitor the operation of pumps, closures and other devices, collect and execute commands coming from the higher levels. Programmable controllers (PLC) are used to control various processes based on the data and the built-in algorithm.

According to the given specifications, a control panel was created in a suitable HMI for the control and monitoring of waste water treatment, which requires communication between the HMI application and local PLC controller.

A program that provides the appropriate behaviour of the valve, placed at the entrance and the control of the pumps was written in a ladder diagram. The alarm and monitoring system is of the highest importance.

THE BRAIN OF THE SYSTEM: NX-ERA XPRESS

NX-ERA Xpress brings you world-class technology at a cost-effective price – for entry-level applications. Packed with advanced features, NX-ERA Xpress micro PLC delivers high-speed processing power in a compact design with embedded I/O.

  • Utilization of labour in other sectors where automation is not feasible
  • Accurate data/information can be obtained, real time operation and better process control

THE OUTCOME

Compared with the traditional manual control sewage treatment plant, there are several advantages in applying PLC to the sewage treatment.

  • The workload of the operator is greatly reduced and the labour intensity is lessened
  • Using the computer to process the data and make the chart makes the sewage treatment more scientific in management
  • The use of PLC system for the rational use of energy and equipment reduces energy consumption, and achieves obvious economic benefits
  • The PLC system and adoption of high and new technology in the process, equipment and management, has greatly promoted the scientific progress of the industry, creating obvious social and economic benefits.
