A method and apparatus are provided for measuring the concentration of contaminants in an aqueous water system, wherein the contaminants are measured with the bioreactor containing a biofilm or microbial community which acts on the water to be analyzed to provide a measure of the amount of the dissolved organic carbon which is biodegradable. A bed for facilitating regulation of water flow through the bioreactor is provided, and an autosampling mechanism enables the measurement of total organiccarbon, inorganic carbon and oxygen ,between sample inflow and sample outflow atspecified time intervals.
Cette invention concerne une tête rotative de dégrossissage à porte-couteaux multiples répartis sur sa périphérie. Chaque porte-couteau comprend en bout une lame dégrossisseuse dont l'arête se déplace dans un plan perpendiculaire à l'axe de rotation de la tête de dégrossissage. Des lames de dressage sont intercalées entre les porte-couteaux pour produire une surface lisse sur la grume dégrossie. Des enclumes disposées en avant des lames de dressage compriment la face dégrossie. Ces lames et les enclumes correspondantes sont montées sur des supports amovibles.
