Understanding Water Quality Parameters
This document details key carbon-related parameters used for measuring organic load in water, including Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), Total Organic Carbon (TOC), Dissolved Organic Carbon (DOC), Spectral Absorption Coefficient (SAC), and UV Transmission (UVT). These parameters are crucial for assessing water quality and managing wastewater treatment processes.
While TOC, DOC, COD, and BOD provide direct measures of organic content, SAC often serves as a surrogate parameter. UVT, measured concurrently with SAC, is valuable for controlling disinfection plants.
The document outlines various fields of application for these measurements, such as municipal wastewater treatment plants (inlet, biological cleaning, outlet, centrate water), micropollutant removal, surface waters, and disinfection plants.
Advanced Spectral Online Sensors
Xylem Analytics' WTW brand offers advanced spectral online sensors, including the CarboVis® and NiCaVis® series. These sensors utilize UV-VIS and UV spectral ranges to provide comprehensive data. They are designed for high accuracy, with capabilities to compensate for turbidity and the influence of nitrate and nitrite, ensuring reliable COD measurements.
Key features of these sensors include integrated ultrasonic cleaning for low maintenance, the ability to measure multiple parameters without reagents, and construction with durable materials like titanium and peek for use in corrosive environments.
