Earth's water reserves

Water is the source of life and the continuation of life for living organisms, as well as a fundamental factor in the emergence of human communities and civilizations. Today, the total volume of the Earth's water, which is the source of life for all organisms, has remained almost constant and unchanging since its formation. These water resources were created about 4.5 billion years ago.

water hardness

Hard water is a term used to describe water containing cations of calcium, magnesium, strontium, iron, manganese, etc. Since the amount of strontium, iron, and manganese in water is very low, calcium and magnesium cations are considered the main cause of water hardness.

Radiator package anti-fouling

One of the most important measures that is prioritized with the approach of the cold season and the start-up of heating systems is to investigate problems with radiators and packages. One of the most important reasons that can cause radiators to not heat evenly is the deposition of deposits and debris inside the radiator fins.

Descaling of marine equipment

Marine equipment deposits, which are mostly calcium and magnesium, act as an insulator between the metal surface and the water and cause the metal temperature to increase, resulting in reduced engine cooling. Marine equipment descaling plays a significant role in reducing costs, including fuel consumption, equipment maintenance, washing, etc.

Corrosion process

Corrosion of metals is the process in which metals reach their original oxidation numbers. In fact, corrosion of metals is an oxidation-reduction reaction in which the metal is oxidized by its surroundings. Typically, oxygen from the air acts as the oxidant in these processes.

Oxygen scavengers

Oxygen scavengers, oxygen scavengers, oxygen absorbers, anti-oxygen or (oxygen scavenger) are used to remove oxygen in various industries. The oxygen scavenger reacts with dissolved oxygen and prevents the reduction of oxygen to hydroxide ions, thus acting as a corrosion inhibitor.

Water disinfection

Before entering the water supply network, the contaminants in drinking water contain high amounts of minerals and metals as well as pathogenic microorganisms, most of which are destroyed in various ways. Performing various purification strategies does not have much effect on the pathogenic bacteria present in the water, and for this reason, various methods, equipment, and materials are used in the chemical purification stage to destroy these bacteria.

Coagulants

Coagulants are key components for the wastewater treatment process that stick to the suspended solids and settle them so that they can be easily removed and the treatment process is carried out. It is very important to choose the type and amount of coagulant to prevent non-compliance and overdraft as well as to reduce the cost of consumption. The appropriate and practical choice of a coagulant can be critical for the success of a process. Coagulants are used to remove the disorganization of colloidal suspensions and neutralize suspended solids.
