BOD5 analyzer introduction and the dangers of high BOD
The BOD meter is an instrument used to detect organic pollution in water bodies. BOD meters use the amount of oxygen consumed by organisms to break down organic matter to assess water quality. The principle of the BOD meter is based on the process of decomposing organic pollutants in water by bac...Read more -
Overview of various commonly used water treatment agents
The Yancheng water crisis following the blue-green algae outbreak in Taihu Lake has once again sounded the alarm for environmental protection. At present, the cause of the pollution has been initially identified. Small chemical plants are scattered around the water sources on which 300,000 citiz...Read more -
What to do if COD is high in wastewater?
Chemical oxygen demand, also known as chemical oxygen consumption, or COD for short, uses chemical oxidants (such as potassium dichromate) to oxidize and decompose oxidizable substances (such as organic matter, nitrite, ferrous salts, sulfides, etc.) in water, and then Oxygen consumption is calcu...Read more -
How high is the salt content that can be treated biochemically?
