The Environmental Problem: Chemical Over-Dosing in Water Treatment
Chemical dosing is often based on fixed schedules or infrequent manual sampling. This leads to chemical over-dosing, which increases sludge production, raises operational costs, and contributes to environmental pollution.
Excess coagulants, flocculants, and disinfectants create:
- Higher sludge volumes
- Increased carbon emissions from chemical production and transport
- Residual chemicals entering rivers and lakes
- Difficulty meeting sustainability and ESG targets
The core issue is simple: plants cannot optimise dosing without continuous, real-time monitoring of water quality.
The Solution: Real-Time, High-Accuracy, Low-Maintenance Optical Monitoring
Photonic Measurements provides predominantly reagent-free, high-accuracy, low-maintenance instruments that deliver continuous, real-time monitoring, allowing operators to move from fixed-schedule dosing to dosing that responds to actual water quality reducing both over-dosing and under-dosing risk.
Relevant Photonic Measurements Products by Category (view products)
Drinking Water (view application)
- UV254 Probes / Online UV254 Monitor – provide continuous, real-time, high-accuracy tracking of natural organic matter with low-maintenance operation, so coagulant dose can be adjusted to actual raw water conditions, rather than a fixed schedule.
- UV254 Go! Portable Controllers – for catchment studies and agricultural runoff monitoring where a fixed installation isn’t practical.
- MLSS and TSS Probes – monitor solids concentration so coagulant dosing isn’t driven by guesswork about solids removal.
Wastewater (view application)
- Online Ammonia & Nitrate Probes / UV Nitrate Cleanse, Sample & Monitoring System – support nutrient removal and reduce unnecessary denitrification chemical demand.
- UV254 Probes (wastewater variants) — track organic load (as a COD/BOD/TOC/DOC surrogate) for biological treatment optimisation.
- Komet Multi-Parameter Controller / Multi-Channel SCADA Controller – combine multiple parameters for plants with variable influent conditions.
