Abstract

A method is used for regulating the pH value and other concn. parameters in chemical reactors, reservoirs, etc. with optional mixing characteristics. It is designed for rapid reaction balance achievement using mathematical processing. The control of supplied material concn. is dependent on the outflow concn. which is computed using the input concn. and the expired time. The control of each controlled component is achieved using a control algorithm based on the time between the supply and output to and from the reactor. The duration distributions may be mathematically represented, set equal to each other, displaced in fixed or flow dependent manner, or neglected.
