SCADA Applications in Wastewater Treatment

Installing a SCADA system at the center of wastewater treatment process helps in achieving the most reliable and cost effective processing tool in the industry. SCADA systems offer solutions that are applicable over networks for the treatment of wastewater. These include capabilities such as remote accessibility, predictive maintenance, advanced controls, optimization, and forecasting. SCADA also helps achieve environmental compliance and meet regulations functional in the region where treatment plant is set up. The control network is expandable that helps in meeting the increased demands for clean and pure water supply.

Some of the ways SCADA systems assist in treating wastewater in a treatment plant

1) Superb diagnostic capabilities

With the integration of predictive maintenance practices, SCADA systems allow the detection of problems in equipment and processes even before they take place. This allows for a proactive, efficient and profitable management.

2) Setting up a digital architecture

SCADA systems work in an organized and efficient way and deliver reduced risks in a project with better operations. Through a centralized workstation, access to comprehensive information and data is provided which in turn results in preventative and predictive information concerning process devices as well as mechanical equipment. The information provided is actionable as well as it is reliable, being validated at the source.

3) Data Reporting and Management

The reporting and data management capabilities of a SCADA system ensure effective monitoring and control capabilities that detect and help in isolating system loopholes better. The SCADA systems provide integrated information flow for monitoring systems including Laboratory Information System (LIMS), Financial Information Systems (FIS) and Geographical Information Systems (GIS).

4) Better Control and Monitoring

SCADA solutions in wastewater management allow the operators to unify the plant, process workflows and the locality connected into a powerful and single network that monitors and controls a multitude of applications.

A SCADA system unifies a wastewater treatment plant in the following ways

  • Treatment control for primary and secondary treatment
  • Management of processes such as digestion, Clarifiers, Solids thickening, dewatering, pumping of sludge
  • Coordinating advanced treatment such as Ultraviolet, RO and Microfiltration
  • Controls for treatments such as coagulation, flocculation, sedimentation, recycling, dewatering and chemical treatment.
  • Monitoring of equipment that includes portable and online monitoring, laser alignment, oil analysis and motor diagnostics.
  • Taking care of instrumentation and bus technologies including Fieldbus solutions.
  • Addressing security concerns such as device and equipment authentication, password management, tracking prohibited activities and streamlining user permissions. Intrusion detection is also taken care of by the SCADA systems.

Why SCADA Systems for Wastewater Treatment?

  1. Higher process qualities through coordinated control strategies reducing total suspended solids and biochemical oxygen demands
  2. Reduced chemical usage through tighter monitoring, optimized operations and control capabilities.
  3. Efficient energy savings with integrated real-time processes allowing accurate prediction and forecasting.
  4. Reduction of potential environmental catastrophes with advanced error detection and weather warnings.
  5. Tracking and controlling manpower costs via a centralized control and monitor leading to significant reduction of expenses and time.
