NEW PRODUCTION FACILITIES

Today, in the territory of the Shop of water treatment facilities and external communications (OSiVK) at PJSC Kazanorgsintez, a new facility for production of low-concentrated sodium hypochlorite from dietary salt using electrolytic method, was accepted. Among others, the event was as well attended by Chief Engineer of PJSC Kazanorgsintez Rafael Safarov and General Manager of Company Newtec Umwelttechnik GmbH (Germany) Yuan Gao.

The reason for the event was the commissioning of the object which construction had been included in the Plan of integrated revamp of the OSiVK Shop within 2020. It is designed for introduction of a new method for water disinfection substituting a conventional application of liquid chlorine. This method features environmental, industrial and process safety improving the composition parameters of filtered drinking water.

Today, the significance of the OSiVK Shop transition to a new technology of filtered water disinfection is hardly disputable. Firstly, chlorine used previously refers to highly hazardous substances (Hazard Class 2). The method of water disinfection using gaseous chlorine delivered in tanks in liquefied state to water treatment facilities is rather “sensitive”. Thus, a highly toxic substance turns water treatment facilities into hazardous production facilities. Possible leakage and accidents pose risks to the employees and people living in surrounding territory (particularly, in a big city). Therefore, it is required to monitor equipment state, to provide for protected areas for chlorine storage, alarm and video surveillance system, and armed guards at the facility.

The above mentioned will not be required in case of using sodium hypochlorite. In terms of toxicity, it refers to low hazardous substances (Hazard Class 4), cause no harm to environment and is not mutagenic and cancerogenic. Its process advantages are evident.

When using, transporting and storing sodium hypochlorite, any situations related to chlorine emission are excluded. Finally, the facility operation, namely sodium hypochlorite dosing for disinfection process is fully automated excluding the “human error”.
