Statistical description of influence of biogenic compounds on process reduction of organic substance from municipal sewage in functioning treatment plant

The subject of this paper is the statistical analysis and mathematical description of the influence of biogenic compounds on the process reduction of organic substance from a municipal sewage. The proposed considerations are based on the industrial database obtained from the real functioning sewage treatment plant. The discrete-time linear problems are estimated by using the adequate statistical estimators. The correlation and spectral density functions are applied to analyse of the process purification of municipal sewages. The mathematical analysis of this process is attained by means of the matrices at the time and frequency domains.
