Ivan Tikhonov The article deals with the problem of operational control of the process of ion water softening. The dependence of the electrical conductivity of water on its hardness value for the water softening process is presented. The article presents a control system for the water softening installation based on programmable relay. The results of […]

Ivan Tikhonov Annotation This article discusses the existence of various forms of carbon dioxide in water. The importance of measuring the pH value in determining the ratios of bicarbonates, carbonates and hydrates is shown. The article presents a method for calculating the pH value of water depending on the ratio of various forms of carbon […]

Ivan Tikhonov The article presents a method for calculating the pH value, which corresponds to the saturation of water by calcium carbonate and compares this pH value with the pH value obtained by calculating with Langelier saturation index and Stiff & Davis index. Corrosion and scale formation are the main problems in the usage of […]

Ivan Tikhonov In the design and operation of low-pressure steam boilers there is a number of significant difficulties in the organization of water-chemical mode (WCM) of their work. Water-chemical mode (WCM) of operation of a steam boiler should ensure trouble-free and cost-effective operation of the equipment and pipelines of the boiler. WCM of a boiler […]

Tikhonov I.A. The presence of dissolved corrosive gases CO2 and O2 in water causes corrosion of equipment and pipelines. As the water temperature increases, the mobility of oxygen molecules increases, and the corrosive aggressiveness of water increases. The problem of removing oxygen and carbon dioxide from water is solved mainly in two ways. It is […]
