Overview
The GreenPrima PROC ON2 000 Municipal Wastewater Colorimeter is a dedicated optical analyzer engineered for continuous, reagent-free measurement of color intensity in aqueous matrices using UV-VIS absorption spectroscopy. It operates on the principle of spectrophotometric quantification of light absorbance at defined wavelengths (typically within 400–700 nm), calibrated against the Platinum-Cobalt (Pt-Co) scale—also known as the Hazen scale—per ASTM D1209 and ISO 6271. Designed specifically for municipal wastewater treatment plants, the instrument delivers stable, traceable color assessment without chemical addition, eliminating analytical drift associated with wet-chemistry methods. Its optical architecture integrates dual-beam referencing and temperature-compensated photodetection to ensure high reproducibility across variable sample conditions—including turbid or suspended-solid-laden effluents—where conventional colorimeters often suffer from scattering interference.
Key Features
- Reagent-free operation: No consumables, no secondary waste generation, fully compliant with zero-chemical discharge requirements.
- Multi-mode monitoring: Supports manual spot measurement, programmable timed acquisition (e.g., every 15 min), and continuous real-time output via analog or digital interfaces.
- Robust optical path design: Quartz flow cell with anti-fouling geometry and integrated self-cleaning cycle minimizes maintenance frequency; optical windows resist biofilm adhesion and chemical degradation.
- Long-life LED光源: UV-VIS broadband LED source rated for >10 years under continuous operation (L50 lifetime), eliminating lamp replacement cycles common in halogen-based systems.
- Intelligent embedded control: Fully automated sequence including auto-zeroing (using deionized water or air reference), auto-calibration (with certified Pt-Co standards), auto-flush, and fault diagnostics with event logging.
- Industrial-grade enclosure: IP65-rated stainless steel (1.4435 / SS316L) housing suitable for outdoor or wet-process environments; optional ATEX Zone 1/2 certification available for hazardous area deployment.
Sample Compatibility & Compliance
The PROC ON2 000 accommodates a broad range of liquid matrices—including raw and treated municipal wastewater, industrial process effluents (e.g., pulp & paper bleaching streams, textile dye baths), potable water, seawater, and surface runoff—with minimal pre-treatment. Its flow-through quartz cell (sample volume <100 mL) tolerates suspended solids up to 1000 mg/L without signal distortion, thanks to proprietary optical path correction algorithms that decouple true color from turbidity-induced scatter. All measurements adhere to internationally recognized standards: ASTM D1209 (Standard Test Method for Color of Clear Liquids), ISO 6271 (Water Quality — Determination of Colour), and EN ISO 7887 (Water Quality — Examination of Colour). The system supports GLP/GMP-compliant data integrity through audit-trail-enabled firmware and time-stamped measurement records stored on internal 8 GB SD card.
Software & Data Management
The onboard controller features an 8.5″ TFT color touchscreen (800 × 480 px, LED-backlit) with intuitive HMI navigation and multilingual UI support. Measurement data are timestamped and archived locally with configurable retention policies. USB 2.0 interface enables secure export of CSV-formatted datasets for LIMS integration or offline statistical analysis. Analog 4–20 mA output (isolated, ≤0.5% FS accuracy) provides seamless connection to DCS/SCADA systems. Digital communication includes RS485 Modbus RTU (slave/master configurable), supporting remote configuration, real-time parameter polling, and alarm status reporting. Firmware updates are performed via encrypted USB stick, ensuring version control and cybersecurity compliance per IEC 62443-3-3 guidelines.
Applications
- Municipal wastewater treatment: Real-time monitoring of color removal efficiency across coagulation, flocculation, and advanced oxidation processes.
- Pulp and paper industry: Control of bleach plant effluent color prior to discharge; optimization of chlorine dioxide dosing.
- Textile manufacturing: In-line verification of dye bath exhaustion and post-rinse clarity compliance.
- Pharmaceutical and cosmetic wastewater: Detection of chromophore-containing organic residues in regulated effluent streams.
- Environmental monitoring stations: Long-term trend analysis of colored dissolved organic matter (CDOM) in rivers and estuaries.
FAQ
What color scale does the PROC ON2 000 use for quantification?
It reports results in Pt-Co units (Hazen scale), with factory calibration traceable to NIST-certified liquid standards.
Can the instrument operate under high-turbidity conditions?
Yes—its optical compensation algorithm corrects for Mie scattering effects up to 100 NTU; optional turbidity compensation module available for >100 NTU applications.
Is the system compatible with existing SCADA infrastructure?
Yes—Modbus RTU over RS485 and isolated 4–20 mA outputs ensure direct integration with most industrial control platforms.
What maintenance is required beyond routine cleaning?
None—no consumables, no reagents, no lamp replacements; recommended quarterly visual inspection of flow cell and gasket integrity.
Does the device meet regulatory requirements for auditable environmental reporting?
Yes—it logs all measurements with date/time stamps, operator ID (if configured), calibration events, and error flags, satisfying EPA 40 CFR Part 136 and EU WFD Annex V documentation mandates.
