Softened water filter introduction

The softened water filter is mainly used to remove the hardness components such as calcium and magnesium ions in water and reduce the hardness of water quality to adapt to the specific needs of different industries.

Softened water filter composition

1. Resin tank (ion exchange column) : This is the core part of the softened water filter, which is filled with ion exchange resin. Resins are usually made of materials such as polystyrene with exchangeable sodium ions on the surface. When water passes through the resin bed, hardness ions (calcium and magnesium ions) will be exchanged by sodium ions on the resin, so as to achieve the purpose of softening the water quality.
2. Resin: Resin is the main medium in the softening process, usually divided into sodium type resin (for softening) and salt regeneration type resin. The sodium ions on the sodium resin have ion exchange reaction with calcium and magnesium ions in water.
3. Salt tank (recycled salt tank) : used to store the salt required for regeneration (usually table salt or specific soft water salt), during the resin regeneration process, the brine solution will be used to wash the resin and restore the exchange capacity of the resin.
4. Control valve: automatic control softener operation, regeneration, backwash and other processes, including time control, flow control or water quality induction control and other types, according to the preset program or according to the actual use of automatic trigger regeneration process.
5. Water distributor and water collector: located at the top and bottom of the resin tank, they are used to evenly distribute raw water into the resin bed and collect the softened water after treatment to ensure uniform water flow and improve softening efficiency.
6. Regeneration system: including salt pump (or salt absorber), injector or other regeneration liquid distribution device, used to evenly transport the brine solution to the resin bed for resin regeneration.
7. Backwash device: used to backwash the resin bed before and after regeneration, remove impurities and loose resin, and ensure the good working condition of the resin.
8. Drainage device: in the backwash and regeneration process, used to remove waste water or recycled salt water, to ensure that the system is clean and ready to enter the next working cycle.
9. Safety valve: set on the resin tank to prevent the internal pressure from abnormal increase, play a safety protection role.
10. Pipeline system: Connect the above components, including raw water inlet, softened water outlet, recycled brine inlet, wastewater discharge outlet, etc., to form a complete water flow channel.
Filter material is high quality stainless steel, such as 304, 316, 316L and so on.

Softened water filter for the industry

The softened water filter is mainly used to remove the hardness components such as calcium and magnesium ions in water and reduce the hardness of water quality to adapt to the specific needs of different industries. It is applicable to a wide range of industries, mainly including but not limited to the following areas:
1. Industrial manufacturing: In automotive manufacturing, electronic manufacturing, metal processing and other industries, softened water can be used for cooling systems, boilers, heat exchangers and other equipment to reduce scale deposition and corrosion, improve equipment efficiency and extend service life.
2. Hotel and catering industry: used in hotel laundry, dishwashing, cooking and drinking water supply, softened water can improve food quality, reduce scale accumulation in pipes and equipment, extend equipment life.
3. Health care: hospitals, laboratories, pharmaceutical industry, need high purity water for experiments, cleaning, dispensing, etc. Softened water as a pretreatment, help to improve water quality, meet high standards of hygiene requirements.
4. Construction: In the cooling tower, heating system and water supply system of the building, the use of softened water can significantly reduce the frequency of equipment maintenance and cleaning, avoiding failures and losses caused by hard water.
5. Agricultural irrigation: In agricultural irrigation, softened water can reduce the problem of pipeline blockage, improve irrigation efficiency, and have a positive impact on crop growth to avoid nutrient absorption obstacles caused by excellent water quality.
6. Food and beverage processing: In the production process of food and beverage, softened water can reduce the scaling problem of equipment, ensure the quality of products and the continuity of the production process.
7. Textile and paper: These two industries have high water quality requirements, and softened water can protect production equipment from hard water damage, extend the service life of equipment, and optimize the production process.
8. Power industry: especially steam power plants, softened water is crucial for boiler make-up water, which can effectively prevent scaling inside the boiler, maintain thermal efficiency, and reduce maintenance costs.
9. Central hot water system: such as the central hot water supply system in hotels, schools, hospitals and other places, the use of softened water can reduce water heater and pipeline maintenance, to ensure the quality and efficiency of hot water supply.
10. Beauty salons and spa baths: In these industries, softened water can improve the quality of service, avoid the adverse effects of hard water on the skin and hair, and reduce equipment maintenance.
Softened water filters play an important role in the above industries, by removing the hardness component of the water, not only protect the equipment, improve production efficiency, but also optimize the quality of products and services, and promote the efficient use of resources.

Softened water filter, also known as water softener or water softening equipment, its working principle is mainly to use ion exchange resin to remove calcium and magnesium ions in water (that is, the main component of water hardness), so as to achieve the purpose of softening water quality. The following is the workflow and principle of the softened water filter as follows:
1. Ion exchange process: The core component of the softened water filter is a resin bead containing sodium ions (Na+). As hard water flows through the resin bed, calcium (Ca2+) and magnesium (Mg2+) ions in the water exchange with sodium ions in the resin due to electrostatic attraction. The sodium ions on the resin are replaced by calcium and magnesium ions in the water, and the hardness ions in the water are adsorbed by the resin, thus achieving the effect of softening the water.
2. Regeneration process: With the passage of time, sodium ions on the resin are gradually replaced by calcium and magnesium ions, and the softening ability of the resin is weakened. At this point, a "regeneration" process is required, that is, the regeneration of the resin by salt water (usually using salt NaCl solution). During the regeneration process, the calcium and magnesium ions on the resin are replaced by a high concentration of sodium ion solution through the resin bed to restore the softening ability of the resin. Regeneration process generally includes backwashing, regeneration, slow washing, fast washing several steps.
• Backwash: First rinse with water from the bottom of the resin bed upward to remove impurities and debris in the resin bed, while loosening the compacted resin layer.
• Regeneration: The salt water is injected from the top of the resin bed, and the resin is fully in contact with the ion exchange, and the sodium ions on the resin are restored.
• Slow wash (replacement) : Slowly rinse the resin bed with water to remove excess salt and hardness ions that have been replaced.
• Fast washing (washing) : Finally, quickly rinse the resin bed with clean water until the water is clear, ensuring that there is no residual salt and impurities, ready to enter the softening work again.
3. Automatic control: Modern softened water filters are usually equipped with an automatic control system, which can automatically soften and regenerate the process according to the set program or flow meter, time controller, etc., to reduce manual intervention and ensure continuous and stable soft water supply.
