COD Water Analysis
Measure Chemical Oxygen Demand Reliably
What is COD Water Analysis?
We are the TOC Leader™
Monitor COD Impurities in all Types of Water
Chemical Oxygen Demand (COD) is the amount of oxygen needed to chemically break down organic matter in water using strong oxidants like potassium dichromate. Essentially, the COD value indicates the oxygen required to oxidize all organic substances in the water, measured in mg/l or g/m3. As such, COD water analysis serves as a crucial tool for measuring the organic content in a sample, as it can quantify nearly all organic compounds that can be digested by a digestion reagent.
Moreover, COD water analysis is essential in wastewater management for determining contamination levels. If wastewater contains high organic content, it must be treated before being discharged into receiving waters. Why is this so important? Without proper treatment, microbes in natural water bodies will consume the organic matter, depleting the oxygen in the water. This process, known as eutrophication, can ultimately lead to the death of aquatic life.
WASTEWATER ANALYSIS
Typically, COD water analysis is performed on wastewater to calculate its pollution level. In fact, the higher the organic material in the water, the more harmful it can be to the environment. The standard method for COD testing is the Dichromate-Method, where chemical oxygen demand is determined through chromic acid digestion of organic loads in wastewater. Consequently, this method has become a widely used parameter in wastewater analysis, aiding in the planning of treatment plants, monitoring cleaning efficiency, and even calculating wastewater taxes.
In addition to COD water analysis, it is equally important to monitor other key parameters like total organic carbon (TOC), biological oxygen demand (BOD), and total nitrogen (TN). By doing so, facilities can maintain water quality and ensure compliance with environmental regulations. Hence, comprehensive monitoring is crucial for protecting ecosystems and meeting environmental standards across diverse industries.
