Water treatment for heating system (definition)

Water purification for heating system - is the process of preparing water used in heating system, in order to prevent contamination, scale, corrosion and other negative consequences that may affect the operation and durability of the equipment. Water treatment is an important stage in the maintenance and operation of heating systems, since the quality of water directly affects the efficiency and reliability of the system.

Water treatment for heating system: main tasks of water treatment

1. Removal of solid particles: Various solid particles such as sand, rust and other contaminants can accumulate in the heating system. These particles can clog pipes, radiators and heat exchangers, reducing the efficiency of heat transfer. Mechanical filters are used to remove solid particles. This is water purification for the heating system.
2. Preventing scale build-up: Water containing dissolved calcium and magnesium salts forms scale when heated, which settles on the walls of heat exchangers and pipelines. This leads to a decrease in heat transfer and an increase in energy costs. To prevent scale, water softeners and special chemical additives are used.
3. Reducing corrosion: Aggressive components in water, such as acids or dissolved oxygen, can cause corrosion of metals from which heating system elements are made. To protect against corrosion, corrosion inhibitors and deaeration systems are used, which remove oxygen from the water.
4. Maintaining chemical balance: It is important to control the pH of the water and the dissolved solids content to avoid adverse chemical reactions. Chemical additives can be used to regulate the acidity and maintain optimal water chemistry.

Water treatment equipment:

1. Mechanical cleaning filters: Installed at the entrance to the heating system to remove large solid particles. These can be mud traps, mesh or cartridge filters.
2. Water softeners: Used to remove hardness salts that cause scale formation. Softeners can be ion-exchange or reagent-based.
3. Deaerators: Equipment for removing dissolved oxygen from water, which helps prevent corrosion of internal heating system components.
4. Corrosion inhibitors: Special chemical additives that are introduced into the system to protect against corrosion.
5. Automatic water treatment stations: Complex devices that combine the functions of filtration, softening and regulation of the chemical composition of water, providing complete water purification of the heating system.

Water treatment for the heating system is a necessary step to maintain the efficient and long-term operation of the equipment. High-quality water treatment allows you to avoid many problems, such as clogging, scale and corrosion, which ultimately reduces maintenance costs and increases the reliability of the entire heating system.
