Experience in retrofitting chlorammoniation technology
at the water treatment facilities in Severodvinsk

Summary

The results of retrofitting natural water chlorammoniation technology at the water treatment facilities in Severodvinsk are presented. The specific features of processing river water with a high concentration of organic substances are considered using the example of WTP-1 and WTP-2. It has been shown that using chlorammoniation technology at the water treatment facilities with different input points of ammonium sulfate makes provides for preparing drinking water that meets current standards for basic chemical and microbiological indicators.

Implementing a project of the local wastewater treatment facilities at the poultry farm operated by Chelny-Broiler LLC on a turnkey basis

Summary

The results of pre-commissioning activities at the newly built wastewater treatment facilities of the poultry farm Chelny-Broiler LLC are presented. Calculations of the biological wastewater treatment facilities of the poultry farm were performed using three mathematical simulation software applications: Activated Sludge Expert, Ecosim (developed by May Project JSC), GPS-X. Control of the process equipment of the local treatment facilities is provided by touch screens using a software and hardware suite developed by May Project JSC. It is shown that the use of nitri-denitrification technology at the treatment facilities of the poultry farm according to the modified three-stage scheme of the University of Ghent (MUG) provides for the effluent quality meeting the standards for the main chemical indicators.
