What is BOD in water?

Biochemical oxygen demand (BOD), is the decomposition of organic matter in water into inorganic matter by aerobic microorganisms in water at a certain temperature. It is a comprehensive indicator of the content of oxygen-demanding pollutants such as organic matter in water. Biochemical oxygen demand is an important water pollution parameter. In wastewater, wastewater treatment plant effluent and ...

What is COD in water?

Chemical oxygen demand (COD) is a chemical method to measure the amount of reducing substances that need to be oxidized in a water sample. Oxygen equivalent of substances (usually organic) that can ...

Process Removes Ammonia Pollution From Wastewater and Provides Useful Chemicals

“We fulfilled a complete water denitrification process,” said graduate student Feng-Yang Chen. “With further water treatment on other contaminants, we can potentially turn industrial wastewater back to drinking water.” Chen ...

Precipitation, Flocculation and Sedimentation Technology

Proven, resilient process for wastewater treatment that has been used successfully for many decades. Safe treatment of wastewater to required limit values. In the precipitation process, dissolved ions are converted into insoluble compounds in physico-chemical reactions triggered by the addition of suitable chemicals that are partly developed in-house. In the subsequent flocculation process, tiny ...
