Aeration Air Flow Measurement Problem:

An Integrated pharmaceutical plant with various departments such as API bulk drugs, tablets, liquid syrup manufacturing facility has a variable load of effluent water with a wide range of toxic organic and inorganic effluent into the effluent treatment plant for processing. This poses a challenge to maintain DO levels with respect to aeration air injection for BOD,COD & TOC control as per regulatory norms for resuage.

Air Blowers are operated on a fixed pressure control loop which creates a problem on inefficient DO controls. DO is a function of air flow not pressure. Efficient Dissolved Oxygen ( DO) control is a challenge to obtain without accurate aeration air flow metering. Ineffective DO control means loss of energy and insufficient bacterial growth for optimum BOD levels.
