Hydrogen Sulfide treatment- H2S Gas in Wastewater - Aquafix
Hydrogen Sulfide treatment- H2S Gas in Wastewater - Aquafix

Hydrogen Sulfide (H 2 S) often is a colorless gas with a rotten egg odor, which is commonly referred to as ‘sewer gas’. H 2 S gas is highly poisonous and highly corrosive in wastewater applications. There are various problems associated with hydrogen sulfide generation, such as toxicity, noxious odors, and the generation of corrosive sulfuric acid.

Chemical oxygen demand - Wikipedia
Chemical oxygen demand - Wikipedia

In environmental chemistry, the chemical oxygen demand is an indicative measure of the amount of oxygen that can be consumed by reactions in a measured solution. It is commonly expressed in mass of oxygen consumed over volume of solution which in SI units is milligrams per litre. A COD test can be used to easily quantify the amount of organics in water. The most common application of COD is in quantifying the amount of oxidizable pollutants found in surface water or ,wastewater, …
