Water Environment
Focused Photonics Inc. (FPI) protects aquatic ecosystems with its precision Water Environment Monitoring Systems, delivering real-time analysis of COD, ammonia nitrogen, total phosphorus, total nitrogen, heavy metals, and flow in rivers, wastewater, and drinking sources. Our SIA and WOA series integrate UV absorbance, electrochemical, and ion-selective technologies for compliance with EPA, GB 3838-2002, and EU WFD standards.
Aquatic Audit: Principles of Water Environment Detection
Water environment monitoring employs optical, electrochemical, and ion-selective techniques to quantify pollutants by measuring absorbance, potential, and ion binding. FPI’s systems utilize UV absorbance at 254 nm for COD (0-1000 mg/L, ±0.1 mg/L), electrochemical ISE for ammonia nitrogen (0-50 mg/L, ±0.05 mg/L) and pH (0-14, ±0.01), and flow-compensated sensors for total phosphorus/TP (0-10 mg/L, ±0.1 mg/L) and heavy metals (Pb/Cd/Hg, 0-1 mg/L, ±0.01 mg/L), achieving sensitivities per GB 3838-2002.

This methodology, evolved from titration standards since the 1970s, integrates pretreatment for turbidity up to 500 NTU and AI for speciation. FPI refines it with drift-free optics and temperature compensation (0-60°C), ensuring <1% uncertainty per ISO 17294. In 2025’s smart water era, our networks fuse in-situ sensors with satellite hydrology data, distinguishing point-source vs. diffuse pollution to inform EU WFD reporting and SDG 6 targets.
