EPR 2016: Environmental Permitting Regulations Compliance
Operating under the Environmental Permitting (England and Wales) Regulations 2016 (EPR) leaves zero margin for error. If your site discharges trade effluent, process water, or treated wastewater, you are legally bound to strict concentration limits. Relying on intermittent, manual grab-sampling leaves your business highly vulnerable to unmonitored pollution events and severe regulatory prosecution.
EPR Compliance requires - Sudden effluent spikes risk permit breaches and fines.
- Ammonium is one of EPR's most scrutinized pollutant.
- Thousands of sites demand low-maintenance monitoring.
- Oxidised nitrogen levels are hard to police manually.
- Manual calibration drift weakens compliance records.
| SWS DropletSens™ delivers - 24/7 continuous monitoring to enable automated dosing.
- Berthelot method tracks Total Ammonia Nitrogen (TAN)
- 15 min in-field maintenance once every three months.
- Griess method for continuous tracking of NO2 & NO3.
- No ongoing calibration. Internal control to confirm no drift.

SouthWestSensor's DropletSens™ platform acts as your continuous, automated on-site guardian. By delivering real-time, high-frequency, lab-quality chemical data for key regulatory markers—including ammonium, nitrate, nitrite, and phosphate—our online analysers enable you to detect process anomalies instantly and prevent EPR permit breaches before effluent leaves your site.
Mitigating the Risk of Effluent Discharge Permit Breaches
Under the EPR 2016 framework, the Environment Agency (EA) enforces strict "polluter pays" principles. Regulatory breaches can lead to formal warning letters, enforcement notices, suspension of operations, or unlimited court fines depending on the severity of the incident.
Common industrial challenges that lead to unexpected permit breaches include:
- Shock Loading: Sudden, massive chemical or organic spikes from plant washdowns, chemical leaks, or process upsets that overwhelm on-site treatment systems.
- Biological Treatment Failure: Temperature drops or toxic chemical inflows that kill off the nitrifying bacteria in your activated sludge, causing ammonium levels to skyrocket.
- Ineffective Chemical Dosing: Under-dosing coagulants, which allows orthophosphate concentrations to breach strict sewer or river discharge limits.
Deploying SWS online analysers gives your operators 24/7 visibility into effluent dynamics, facilitating immediate, automated chemical dosing adjustments or flow diversion to holdback tanks during a spike.
Continuous, Lab-Quality Nutrient Monitoring for Industrial & Trade Waste
The DropletSens™ series provides the exact chemical metrics required to satisfy complex environmental permit conditions:
- Ammonium & Ammonia Monitoring: Utilizing pH-mediated conversion and the Berthelot method, our sensors continuously measure Total Ammonia Nitrogen (TAN)—a highly scrutinized pollutant under EPR rules due to its extreme toxicity to aquatic life.
- Phosphate & Orthophosphate Tracking: Utilizing the definitive Molybdenum Blue wet-chemical test to track reactive phosphorus, allowing precise dosing control for industrial phosphorus-removal systems.
- Nitrate & Nitrite Analysis: Built on the established Griess test method to continuously track total oxidized nitrogen (TON) levels in final effluents.
Why DropletSens™ Succeeds in Challenging Industrial Effluents
Industrial trade wastes are notoriously difficult to monitor. High chemical oxygen demand (COD), fluctuating pH, grease, suspended solids, and chemical additives cause traditional optical and electrochemical probes to drift or fail within days. SWS's advanced nanodroplet microfluidics bypass these physical vulnerabilities entirely:
- Zero Calibration Drift: An onboard standard solution automatically runs routine performance checks, guaranteeing fully quantitative, audit-ready compliance records without manual calibration.
- Sealed Reagent Chemistry: The chemical reaction occurs isolated within microscopic channels, shielding the sensitive detection optics from direct contact with the harsh sample matrix.
- Low Operating Cost (Opex): Microfluidic scale means minimal reagent use. A single cartridge lasts for up to 90 days in continuous use, meaning your maintenance teams only need to service the unit four times a year.
Seamless SCADA Integration and Active Pre-Filtration
To act as a true compliance tool, our online analysers are designed to fit effortlessly into your existing industrial control systems:
- Industrial Communications: Stream data seamlessly to your centralized SCADA, PLC, or telemetry systems using Modbus, RS232, RS485, or Bluetooth.
- Tough Pre-Filtration for High Solids: For heavy-industrial effluents, we supply integrated pumped systems featuring active, self-cleaning pre-filtration options. Choose between our mechanical Rotorflush modules or ceramic, back-washable Cembrane Silicon Carbide (SiC) systems to ensure an uninterrupted, clog-free stream.
