Waste water impact determining method, involves mathematically estimating chemical oxygen requirement of waste water under application of result of determination of sound velocity, density and conductivity at waste water

摘要

The method involves inline determining sound velocity, density and conductivity at waste water from a brewery by a programmable density-sound-analyzer. Chemical oxygen requirement of the waste water is mathematically estimated under application of the result of the determination by the density-sound-analyzer. A filter is provided for extraction of low solid waste water samples for the determination, and a unit is utilized for determining the temperature of the water. An independent claim is also included for a method for implementing the device for determining the impact of waste water from brewery by the organic material.
