Commissioning – the key stage of putting treatment facilities into operation

Summary

The issues related to the commissioning of the equipment and wastewater treatment facilities are considered. A brief review of the history of commissioning the facilities in the Soviet Union and in present day Russia is given. The problem areas of adjusting every equipment assembly, the algorithm of work performance and the required results are shown. The attainment of sustainable performance is provided by quality and skilled commissioning. Correct visual evaluation of the equipment state carried out during the acceptance for commissioning procedure is very important. Nonobserved defects and faults in the process line will cause fast assembly fail which can result in an accident. The principles of «My Project» Company activities related to commissioning are presented. Special attention is paid to adjusting biological treatment in aeration tanks: from the front end engineering to the routine maintenance of the assembly.

Stages of launching a biological treatment plant at the wastewater treatment facilities with dosing easily oxidable organic matter

Summary

Issues related to commissioning a biological treatment plant at the facilities for household and similar in composition wastewater treatment during the trial start of the treatment facilities are considered. The stages of commissioning a biological treatment plant at the wastewater treatment facilities with «inoculating» activated sludge from the operating biological treatment facilities and with dosing easily oxidable organic matter are considered in detail. The equipment configuration of the WWTP-9 produced by Germes Group is described. All stages of the biological treatment plant commissioning are considered through the example of the start-up of WWTP-9 with the use of numerous experimental data. The periods of biological treatment plant commissioning stages have been determined. The problems of adjusting the biological treatment plant and the ways of their elimination to achieve the required result are presented. The technology used at the WWT facilities provides for the effluent quality that meets the requirements for the discharge into a water body of commercial fishing importance.
