Abstract

A promising approach to amino acids extracting from industrial enterprises wastewater is ion-exchange sorption. The plant for the sorption extraction of amino acids from wastewater includes three ion-exchange columns of vertical type, a reservoir for source water, condensate and regenerating solution tanks equipped with heating elements, and control valves system. The method of automatic control of the process of ionexchange sorption of amino acids from wastewater was developed. It includes monitoring of concentrations of waste water components, measurement of the flow rate of liquid solutions and their level in tanks. Information on the course of the process of amino acids ion-exchange sorption from wastewater is transferred from level sensors in the source water tanks, the distillate and desorption solution, the initial water acidity and when it is fed to ion exchange columns at distillate and desorbing solution temperatures, the concentration of the target component in the source water and water at the output from ion-exchange columns and flow through secondary devices to the microprocessor. Then, through the digital-to-analog converters, the correcting signal is sent to the actuators to change the performance parameters of the equipment depending on the selected criteria. Additional measurement of modes and changing the parameters of the equipment operation depending on the selected criteria allows to increase the accuracy of control and to minimize energy and material costs.
