Reliability of Sewage Treatment Process in SBR Reactor with the Use of Statistical Quality Control

Piotr Bugajski , Paulina Śliz , Karolina Kurek


The purpose of the work was to determine the reliability of the selected pollution indicators removal i.e. CODCr, ammonium nitrogen, total phosphorus and total suspension from the SBR- type collective sewage treatment plant. The level of operational reliability of sewage treatment plants was determined by means of quality control using control charts. Physical and chemical analyzes of raw and treated wastewater, were carried out in the period from 2008 to 2016. As a result of the control charts analysis, it was found that in the sewage treatment plant there was full stability of the process of total suspended solids reducing. In the case of CODCr, total phosphorus and ammonium nitrogen, there were noticed occasional samples groupings below the lower characteristic line, which could indicate a disturbance of process stability. However, they did not affect the efficiency of wastewater treatment in the tested treatment plant. Therefore, it is possible to confirm the thesis that the method of determining the reliability of the treatment plant operation by using control charts is an easy and effective tool for the operator to detect any disturbances and irregularities in the process occurring in the tested object and enables to take appropriate action to remove them.
