<p>A method of and a system for determination of wastewater biodegradability, whereby a sample of wastewater is introduced into a reaction chamber of a measuring apparatus. The sample of wastewater is subjected to oxygen-containing air, and measurements are performed of a dissolved oxygen (DO) content of the sample of wastewater. A rate of oxygen consumption is determined, and organic matter fractions of the sample of wastewater are determined on the basis of the determined rate of oxygen consumption of the sample and on the basis of microbial properties of said organic matter fractions. A model of the sample of wastewater, e.g. the organic matter fractions and their microbial properties, may be utilized for simulating the oxygen consumption rate of the sample.</p> |
