Organic Loading Rate - an overview | ScienceDirect Topics

The optimum range of organic loading rate depends on the nature of the organic substrates to be added, and the type of wastewater to be treated. To successfully treat wastewater with a low COD, such as mining and metal processing wastewater, the addition of high amounts of external organic compound is necessary ( Hashemi et al., 2016; Muhammad
