The solubility of iron ions is controlled by the concentration of carbonate. Since groundwaters are often oxygen-deficient, soluble iron in groundwaters is usually in the form of iron salts. Upon exposure to air or the addition of oxidants, iron is oxidized to the ferrous state and can be hydrolyzed to produce the insoluble red hydrated iron oxide.

Copper exists in its elemental state, but is also found in many minerals, the most important of which include sulfide compounds (such as chalcopyrite), as well as oxides and carbonates. Copper is widely used in electrical wiring, roofing materials, various alloys, pigments, cookware, plumbing, and the chemical industry. Copper salts are used in water supply systems to control biological growth in tanks and distribution pipes and to catalyze the oxidation of manganese.

The most common raw materials used for cement production are limestone, marls and clay (although other materials can also be used). The selected materials are crushed and mixed to produce a suitable raw material for use in the subsequent processes. Approximately 1.50-1.60 tons of dry (raw) mix is ​​required to produce 1 ton of clinker due to the calcination of the limestone component of the raw material.

Both iron and steel have played an important role in the development of human civilization over several thousand years, and have been used in agriculture, construction, power generation and distribution, the manufacture of machinery and equipment, in the home, and in medicine. Along with coal and cotton, iron and steel were the raw materials on which the Industrial Revolution began. Technological developments from the early 18th century onwards led to significant increases in production, for example, by replacing charcoal with coal and coke and by developing the pudding process to convert hot metal into steel.

Disinfection of drinking water is performed to inactivate or eliminate pathogens, with the goal of achieving basic drinking water standards. Disinfection fulfills part of the primary goal of water purification, which is to provide water free of pathogenic organisms. Fluoridation is used as a method to prevent dental cavities. Public sensitivity to fluoridation and new findings about disinfection byproducts have made both topics hot and controversial issues of the day.

Aeration is the process of contacting water with air or other gases to transfer volatiles from the liquid to the gaseous phase and dissolve beneficial gases in the water. It is possible to remove volatiles such as dissolved gases, volatile organic compounds, and various aromatic compounds that cause taste and odor through aeration. The gases that dissolve in water during this process are oxygen and carbon dioxide.

The process of ion exchange has been used since ancient times. Eratosthenes Thallis used this process to contact salt water with soil to produce fresh water. In 1845, Thomson showed that when water containing ammonium sulfate was passed through soil, calcium sulfate would be produced in the effluent.

The affinity of some metals in a corrosive environment initially increases normally with increasing concentration of corrosive agents (oxidizing power of the solution), and metal corrosion is intensified, but at a certain concentration of corrosive agents, the corrosion rate suddenly decreases significantly and the metal loses its affinity and becomes inactive. The reason for the reduction in corrosion at a certain concentration of oxidizing components is the formation of a protective or inactive layer on the metal surface. The protective layer can be oxide, hydroxide or other compounds. This phenomenon is called rusting.

Downhole corrosion is one of the most important problems facing the oil and gas industry. By using various methods such as selecting appropriate materials, surface coating, use of corrosion inhibitors and cathodic protection, the corrosion rate can be significantly reduced. A better understanding of corrosion mechanisms and the development of new technologies can help improve efficiency and reduce costs in this industry.

Chiller is derived from the Latin word Chill, meaning to cool. Various cycles are used to create refrigeration, the most important of which are the compression refrigeration cycle, the absorption refrigeration cycle, and the thermoelectric refrigeration cycle.

Mitreh Cooling Tower Anti-Fouling is one of the innovative products of Abrizan Company. This product, using an excellent composition, serves all industries and large buildings that use cooling towers to exchange and remove water heat. Mitreh's product prevents the reduction of the performance of this system by preventing the formation of fouling. A system that plays the role of a heat exchanger.

Any system where temperature and water are the main elements for its operation inevitably requires the invention of Abrizan Company, called Industrial Mitreh, because wherever there is temperature and water, the formation of sediment is inevitable, unless a substance is used that suspends these sediments. This is the main function of an excellent anti-sediment solution.

The set of factors affecting metal corrosion can be divided into two main categories: environmental factors and intrinsic factors of the metal.

Solids in water refer to suspended or dissolved materials in drinking, surface and brackish waters, as well as domestic and industrial wastewaters. Solids may affect water and wastewater quality in a number of ways. Waters with high dissolved solids are generally of lower quality and may cause adverse physiological responses in the consumer, so a maximum of 500 mg of solids per liter is desirable for drinking water.

Thermoelectric power plants boil water to create steam, which then turns turbines to generate electricity. The heat needed to boil the water can come from burning fuel, nuclear reactions, or the sun. As the steam passes through a turbine, it must be cooled back to water before it can be used again to generate more electricity. Colder water cools the steam more effectively, increasing the efficiency of electrical energy generation.

The incidence of each type of metal corrosion varies, and the importance of each type will vary across systems and environments. On the other hand, there are striking similarities in the distribution of corrosion damage across similar industries, and by comparing them, it can be seen that corrosion problems in similar industries are very similar.
