ABSTRACT:
A method for controlling and/or optimising a process in which a biological system comprising mixed cultures of microorganisms, biodegradable material, one or more biogenic fluorophores and optionally other soluble and/or insoluble and/or suspended substances in an aqueous environment is subjected to one or several separation processes and/or to chemical reactions and/or to biological treatment so as to obtain as a final product purified water which has a substantially lower content of biodegradable matter than the biological system, which method comprises monitoring the microbiological activity of the biological system and/or fluctuations thereof by on-line measurement of fluorescent emission and/or variations therein for at least one of the fluorophores in the system when irradiated with light and controlling one or several parameters of the process by using results from the measurement as measured variable(s) in an on-line automatisation system.
