Question: What is a good way to debottleneck a chemical water treatment facility?
Keywords: v1i6,debottleneck,chemical,water,treatment,facility,plant,wastewater,bod,biological,oxygen,demand
Answer: Most waste water facilities attached to chemical processing facilities were designed to use air as a means of dissolving oxygen into the water. The air used by aerobic agents to break down the unwanted compounds in the wastewater.By substituting pure oxygen for air injection, the amount of dissolved oxygen in the water can be increased five time over what is typically possible by using air. This additional oxygen speeds the treatment process and can significantly increase the capacity of a waste water facility. So much additional capacity can be realized that some companies have avoiding the construction of additional facilities by adding pure oxygen introduction to their facility.Reference: Chemical Engineering Magazine, January 2001
