The article shows how all forms of carbon dioxide in water can be determined by performing only one chemical analysis. Carbon dioxide dissolved in water largely determines its corrosive properties. As a result of the dissolution of carbon dioxide (CO2), carbonic acid (H2CO3) is formedinwater.Therefore, wateracquirescorrosiveproperties.Ifsuchwatercomes into contactwithmetals,thencorrosionwithhydrogendepolarization is possible.Allnaturalwatercontains carbon dioxide.Inthis case, threeforms of […]

The article discusses how it is possible to simply determine the specific salt consumption for the regeneration of the working exchange capacity of cationite in Na form. The specific salt consumption for cationite regeneration is the most important parameter for the high-quality operation of the water softening plant. If this indicator is too high, then […]

The article discusses the possibility of the existence of iron in water in various forms. It is known that iron in water exists in two and trivalent forms. The trivalent form of iron precipitates, i.e. it passes from the liquid into the solid phase and exits the electromagnetic interaction with water molecules. As long as […]

The article describes the physical and mathematical meaning of the pH value of water, the conditions of corrosion processes with hydrogen depolarization, and the article also offers a hypothesis about the causes of self-ionization of water. The water molecule consists of two ions, the hydrogen cation (H+) and the hydroxide anion (OH–), which under normal […]

Ivan Tikhonov The article discusses the system of circulating water supply of a car wash. The main stages of water treatment and wastewater treatment are described. It considers the possibilities of the configuration of the recycling water supply system in order to obtain maximum efficiency of operation of the car wash complex under the condition […]

Ivan Tikhonov Make-up water consumption for a wet cooling tower is determined by the makeup water chemistry. Heat removal in a wet cooling tower occurs due to the evaporation of a part of the water in the cooling tower. As a result of the evaporation, heat is removed from the cooling water. This process is […]

Ivan Tikhonov Acid ion exchange of water is performed to replace all cations found in water with hydrogen cations (H+). As a result, the following reactions occur on the cation exchange resin in the H-form:   Ca(HCO3)2 +2HR CaR2 + 2H2CO3 Mg(HCO3)2 + 2HR MgR2 + 2H2CO3 NaHCO3 + HR NaR + H2CO3   CaCl2+ […]

Ivan Tikhonov Steam condensate is corrosive due to the presence of carbon dioxide in it. As a rule, the concentration of carbon dioxide in the condensate is required to be less than 20 mg/l. The concentration of carbon dioxide in the condensate can be easily determined by knowing the concentration of bicarbonate ion in the […]

Ivan Tikhonov Annotation The article presents a method for calculating the pH value of water based on the carbon dioxide balance of water. An example from the author’s practice is presented. The pH value of natural water is usually determined by the ratio of various forms of carbon dioxide found in its composition. Various forms […]

Ivan Tikhonov This article describes the technology of boiler water quality control with the control of the pH value of boiler water and the value of its electrical conductivity. Examples of this control are provided. The conditions under which this control is sufficiently effective are specified.   Is it possible to control the entire water-chemical […]

Ivan Tikhonov In this article I will try to tell you how the ionic composition of water affects the value of electrical conductivity and how justified is the use of the generally accepted conversion factors of electrical conductivity of water into the salt content of water (in the range of 0.5-0.55) for the vast majority […]
