Our website features about a hundred and fifty internet pages of detailed information on our abilities, analytical approaches, and case histories. A printable summary of our abilities is additionally readily available here.
This can help Enhance the overall environmental overall performance of industries and reduce their influence on h2o assets.
The dichromate approach can be a widely used technique for measuring COD. It requires including a identified surplus of potassium dichromate to the known volume of sample while in the existence of sulfuric acid.
A good COD degree would be 0mg/l, but is not likely doable for many treatment method procedures to accomplish. Ordinarily a suitable greatest COD discharge limit is going to be established by the neighborhood governing entire body e.g. Ecosystem Agency or Drinking water Utility Corporation.
Chemical Oxygen Demand is a crucial evaluate in knowledge the extent of organic and natural pollutants located in surface water or wastewater. It can be expressed in milligrams for each liter (mg/L), which signifies the mass of oxygen eaten for each liter of Answer.

The COD test is commonly made use of as a means of measuring pollutants effecting aquatic ecosystems. Not like the Biochemical Oxygen Demand (BOD) test, which only actions the amount of oxygen eaten by microbial oxidation, the COD test measures the oxygen eaten by chemical oxidation.
Our inline all-rounder for numerous click here programs. Common measuring process for automatic coating thickness measurement and substance testing. Exhibit a lot more
Wastewater Therapy Efficiency: COD measurements are important for assessing the overall performance and performance of wastewater therapy procedures. By measuring the COD of influent (Uncooked) and effluent (treated) wastewater, treatment method plant operators can Assess the usefulness of the remedy system in eliminating natural and organic pollutants.
Coming out in the ’70s from wastewater remedy education and sooner or later operating my wastewater plant A read more very powerful coaching I received and passed on to new Operators was Mastering to run the BOD test twice each week for just a sewage procedure plant.
Chemical Oxygen Demand (COD) is a critical parameter in wastewater cure and drinking water high-quality Assessment. It is a measure of the potential of water to eat oxygen in the course of the decomposition of natural and organic make any difference as well as oxidation of inorganic chemicals such as Ammonia and Nitrite.
Analytical tactics to evaluate organic subject in water, including Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD5), and Whole Natural Carbon (TOC) are widely utilised. Modifications have been proposed for making them quicker, much more delicate, plus much more eco-friendly. The goal of creating an evaluation over a while is to indicate the alterations produced about the standardized methods of Each and every of these methods, and to spotlight the connection between them in the process of ascertaining organic subject in h2o.
Entire Carbon Oxidation: The large temperatures Employed in the combustion course of action make certain the complete oxidation of carbon compounds, supplying exact and dependable measurements.
Alongside one another we will see the right solution for even probably the most demanding purposes – from tactile handheld devices to automation answers.
