A new water purification intake control system adjusts flow rate based on river quality. This system reduces operational costs and waste sludge, improving environmental impact and landfill capacity.

Area of Science:

  • Environmental Engineering
  • Water Resource Management
  • Process Control

Background:

  • Water purification plants face challenges in managing operational costs and environmental impact.
  • River water quality fluctuates, affecting treatment efficiency and resource allocation.
  • Current intake systems may not optimally adapt to real-time water quality variations.

Purpose of the Study:

  • To introduce a novel intake control system for water purification plants.
  • To reduce operational costs and ensure a stable water supply.
  • To minimize coagulant dosage and waste sludge generation.

Main Methods:

  • Development of a new intake control system based on river water quality.
  • Implementation of a flow rate adjustment mechanism linked to water pollution levels.

  • Conducting simulation studies using two years of on-line turbidity data.

    • Main Results:

    • Simulations demonstrated significant reductions in waste sludge.
    • Waste sludge reduction percentages were 5.8% (Year 1) and 8.5% (Year 2).
    • The system effectively adapts intake flow to river water quality.

    Conclusions:

    • The proposed system effectively reduces waste sludge and operational costs.
    • This approach contributes to environmental preservation and extends landfill capacity.
    • Adaptive intake control is a viable strategy for optimizing water purification processes.
