METHOD OF AUTOMATIC CONTROL OF ION-EXCHANGE SORPTION OF AMINO ACIDS FROM WASTE WATER

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to a method of automatic control of ion-exchange sorption of amino acids from waste water and can be used in chemical, food and other industries. The method of automatic control of ion-exchange sorption of amino acids from waste water involves controlling concentration of components of waste water, measuring flow of liquid solutions and their level in reservoirs. Information on flow of the process of ion-exchange sorption of amino acids from waste water is sent to sensors for monitoring level in containers of incoming water, distillate and desorbing solution, acidity of incoming water and during its flow into ion-exchange columns, temperature of the distillate and desorbing solution, concentration of the target component in the incoming water and water at the outlet of the ion-exchange columns and flow through secondary devices, a microprocessor and digital-to-analogue converters to actuating mechanisms for changing parametres of operation of the equipment depending on selected criteria.;EFFECT: invention increases accuracy of control and minimises energy and material costs.;1 dwg
