Improvement of the disinfection system in Mirny
In January 2020, in Mirny, at the water supply facility under the jurisdiction of PTVS LLC, the dosing system of chlorine-containing reagent for disinfection needs was upgraded. Previously, dosing control was carried out by the signal of flow meters. Currently, the system is supplemented with a station for monitoring the content of residual chlorine in water. Adjustments have been made to the decontamination process automation system, which allows controlling the operation of metering pumps. As a reagent for US 10000 and US 20000, low-concentrated electrolytic sodium hypochlorite is used, obtained at the Aquachlor-GPHE installations manufactured by LET LLC.
