Water Treatment Plants -- Filter Efficiency and Maintenance

2025-03-25

Latest company news about Water Treatment Plants -- Filter Efficiency and Maintenance

Transmitters Used:

  • Differential Pressure Transmitters – Monitor pressure drop across filters.
  • Hydrostatic Level Transmitters – Track tank levels for filter backwash control.

Configuration:

  • Mounting Position: Inline with sand or membrane filters.
  • Material: PVDF (Polyvinylidene fluoride) or ceramic sensors for chemical resistance.
  • Range: 0-10 bar, calibrated for low-pressure environments.

Communication Protocols:

  • 4-20mA Loop Powered: Standard for analog control systems.
  • Foundation Fieldbus: Enables communication with advanced DCS systems.
  • IO-Link: Provides real-time parameter updates and predictive maintenance.

Failure Modes & Mitigation:

  • Filter Clogging: Automated backwash triggered based on differential pressure data.
  • Sensor Drift: Scheduled recalibration and auto-zero function.
  • Corrosion in Wetted Parts: Use of anti-corrosion coatings and protective materials.

Results:

  • 25% reduction in water wastage.
  • Maintenance intervals extended by 20%, lowering operational costs.
