The OndaVia Raman Controller Automation (ORCA) system enables on-line, semi-continuous chemical analysis using OndaVia’s proprietary Quantitative Raman Spectroscopy-based methods. The ORCA-204 automated monochloramine analysis fluidic control unit prepares water samples for analysis in an ORCA control unit. Reagent packs are designed for once per hour analysis for one week before replacement.

System Description

  1. Raman Spectroscopy Instrument: The system includes a specialized Raman spectroscopy instrument that employs laser-induced scattering of light to analyze the chemical composition of water samples. Raman spectroscopy is known for its high sensitivity and ability to identify and quantify chemical compounds.
  2. Monochloramine Detection Reagents: The system includes reagents specifically designed for the detection and quantification of monochloramine in water. These reagents may interact with monochloramine to produce characteristic Raman spectra.
  3. Software and Data Analysis Tools: The system includes software and data analysis tools that allow users to process Raman spectra, identify monochloramine peaks, and calculate monochloramine concentrations in water samples.

Applications for Automated Monochloramine Analysis

The system’s primary applications are as follows:

  1. Drinking Water Quality Monitoring: Monochloramine is a common disinfectant used in drinking water treatment. The system enabled automated monitoring and control of monochloramine levels to ensure the safety of drinking water.
  2. Wastewater Treatment: Monochloramine is a wastewater treatment disinfectant used to limit of nitrification. The system helps in optimizing chemical dosing for effective wastewater treatment.
  3. Environmental Monitoring: The system is valuable for environmental agencies to monitor monochloramine levels in natural water bodies. It ensures compliance with regulations and helps assess the impact of discharges on aquatic ecosystems.
  4. Industrial Water Treatment: Industries that use water in their processes, such as food and beverage, pulp and paper, and electronics manufacturing, rely on monochloramine for water disinfection. The system aids in monitoring and maintaining water quality for industrial processes.

Value Compared to Competing Automated Monochloramine Analysis Methods

The Quantitative Raman Spectroscopy system offers several advantages compared to traditional methods and competing techniques for automated monochloramine analysis:

  1. High Sensitivity: Raman spectroscopy is known for its high sensitivity, allowing the detection of monochloramine at trace levels, which may not be achievable with some conventional methods.
  2. Reduced Maintenance: The instrument requires less maintenance compared to some analytical instruments, reducing downtime and operational costs.
  3. Ease of Use: The system can be user-friendly, and its software simplifies data analysis, making it accessible to a broader range of users.
