Wastewater Effluent Monitoring & Compliance Solutions
Discharging final effluent demands absolute precision and reliable compliance data. With tightening regulatory frameworks, rising public scrutiny, and strict pollution penalties, wastewater treatment operators require robust, real-time nutrient monitoring they can trust 24/7.
SouthWestSensor delivers automated, in-situ effluent monitoring solutions that bring lab-quality analysis directly to municipal wastewater treatment plants (WWTPs), industrial process discharges, and Combined Sewer Overflows (CSOs). Our DropletSens™ platform continuously tracks key chemical markers like ammonium, nitrate, nitrite, and phosphate, protecting both your local ecosystems and your compliance record.
Meeting the Mandate: Environment Act 2021 Section 82 Compliance
The introduction of Section 82 of the UK Environment Act 2021 represents a paradigm shift for water companies, requiring continuous upstream and downstream monitoring of water quality (specifically ammonium, dissolved oxygen, pH, and temperature) around all WWTP outfalls and CSOs.
Deploying standard, high-maintenance sensors across thousands of outfall locations is operationally and financially unsustainable. The SWS DropletSens™ platform is engineered specifically to solve this challenge. By using nanodroplet microfluidics, our analysers operate autonomously with ultra-low reagent consumption, requiring maintenance visits only once every three months.
Robust, Low-Maintenance Monitoring for Harsh Effluent Environments
Raw and final effluents are notoriously harsh environments that cause rapid biofouling, drift, and mechanical failure in traditional electrochemical and optical probes. SWS overcomes these challenges through engineering innovation:
- Drift-Free Wet Chemistry: By utilizing miniature, automated standard checks on-board, the system recalibrates itself dynamically, ensuring high-frequency, lab-quality accuracy without manual intervention.
- Protected Microfluidics: The active chemical reaction occurs inside isolated microchannels, shielding the delicate detection optics from fouling by the sample matrix.
- Minimal Consumables: A single, compact reagent cartridge lasts up to 90 days in continuous operation (at standard 15-minute intervals), minimizing routine maintenance overheads.
Complete Systems: Pre-Filtration & Integration Options
Effluent often carries high suspended solids that can clog standard instrumentation. SWS provides fully integrated, pumped online analyser packages equipped with active, self-cleaning pre-filtration systems to ensure continuous operation:
- Passive Filtration: Large-area, non-biofoul polyethersulfone (PES) membrane assemblies.
- Active Rotorflush: A self-cleaning pumped module that mechanically keeps solids away from the intake.
- Cembrane Silicon Carbide (SiC): Flat sheet ceramic membranes featuring automated back-wash and jet-wash cycles for the most demanding industrial effluents.
