Carbon source feeding device and selection
Thread Content
Hello, I would like to ask. My wastewater treatment plant uses the Carrousel 2000 oxidation ditch process. Currently, there is a shortage of carbon sources in the influent water, with an OD value of around 120. The levels of carbon and phosphorus, as well as the carbon-to-nitrogen ratio, in the effluent are abnormal, resulting in excessive levels of total phosphorus and total nitrogen in the effluent. If carbon sources are to be added, which one would be suitable? There is also the installation location and selection of the carbon source feeding device.
COD120 is not low either. What is the inlet TN level? Choosing the oxidation ditch was a mistake; the SBR process would be better
