CASE STUDY
Precision Under Pressure: Enhancing Sludge Flow Accuracy in a Critical WWTP Line
Municipal Wastewater Treatment Plant
Municipal Water & Wastewater
Flowmeter removal and installation; Custom spool fabrication (304 stainless steel); Pipe support and valve installation; Flowmeter calibration and configuration; System documentation delivery
Overview
TMPC was tasked with replacing an unreliable flowmeter on the only sludge pipe at a Northern California WWTP. The upgrade required custom fabrication and installation of an Endress+Hauser Promag W 400 electromagnetic flowmeter, all within a critical 10-hour plant shutdown window to avoid extended operational downtime.
Problem
The existing flowmeter on the WWTP’s only sludge pipe was delivering inconsistent and unreliable readings, impairing the plant’s ability to optimize chemical dosing, manage sludge processing, and maintain regulatory compliance.
Solution
TMPC removed the old flowmeter and installed a new high-accuracy Endress+Hauser Promag W 400 meter with supporting valves, pipe supports, and a custom-fabricated spool piece. The team completed installation, calibration, and commissioning within a 10-hour shutdown window to ensure continuous plant operations.
Results
- Reliable, real-time sludge flow data
- Enhanced operational control and process optimization
- Reduced need for manual monitoring
- Successful completion within a strict 10-hour window
- Minimized plant disruption and risk
