For many companies and people in living environments, water softening equipment is an item worthy of attention. This kind of equipment plays an important role in daily work and life, but many people do not understand this concept. So, what exactly is water softening equipment?
Water softening equipment, as the name suggests, is equipment that reduces water hardness. Hardness refers to the content of salts dissolved in water, that is, the main calcium ions (Ca2+) and magnesium ions (Mg2+). Hard water can in many cases have adverse effects on machinery, plumbing equipment, and even domestic water supplies. So softening water is an important job.
working principle
The main working principle is to utilize the anion and cation conversion principle. Let the raw water pass through the anion and cation converter to remove calcium, magnesium, sodium and other ions in the water. The output water will be closer to pure water. It mainly includes three parts, namely ion exchange part, salt regeneration part and control part. The working principle of softened water equipment is derived from the ion exchange process. The hardness of water is primarily determined by the calcium ions (Ca 2+ ) and magnesium ions (Mg 2+ ) it contains. In the softened water equipment, the raw water will pass through the sodium-type cation exchange resin. The hardness components Ca 2+ and Mg 2+ in the water will be exchanged with the Na+ (sodium ions) in the resin, thereby adsorbing the calcium and magnesium ions in the water to achieve water quality. of softening.
However, after the resin absorbs a certain amount of calcium and magnesium ions, the Ca 2+ and Mg 2+ in the resin will gradually increase, which will gradually reduce the resin's efficiency in removing calcium and magnesium. At this time, regeneration processing is required. The regeneration process mainly involves flushing the resin layer with salt water to replace the hardness ions on the resin, and then discharge the regeneration waste liquid out of the tank, allowing the resin to restore its softening and exchange function. In this way, the water softening equipment can perform the task of softening water continuously and cyclically.
In addition to calcium and magnesium ions, water softening equipment cannot reduce the total salt content in the water during the process of softening water. Such equipment can be used to soften the supply water of air conditioning systems and heating systems and treat domestic water.
The core technology of softened water equipment uses the principle of ion exchange to remove scaling ions such as calcium and magnesium from raw water. When the raw water containing hardness ions passes through the resin layer in the exchanger, the calcium and magnesium ions in the water will be adsorbed by the resin, replacing the sodium ions in the resin. The output water is the so-called "soft water", thus achieving the purpose of softening water quality. Purpose.
Advantage
The advantages of softened water equipment are manifested in many aspects, meeting the various needs of life and industry. First of all, the water produced by softened water equipment has a wide range of applications, ranging from domestic uses to industrial applications. In daily life, softened water for bathing, shampooing, and face washing not only protects the skin of infants and young children, but is also used on a large scale in beauty, laundry and other industries, improving the quality of life of users. Industrial uses are mainly reflected in the softening treatment of boiler water supply, air conditioning systems, etc., which greatly improves the working efficiency and service life of the equipment.
Secondly, the excellent performance of the softening equipment mainly solves the scale problem caused by hard water. Scale has a damaging effect on equipment and pipelines, reducing their working efficiency and shortening their service life. The water treated by the softened water equipment reduces the generation of scale, improves the durability and anti-corrosion of the equipment, and greatly reduces the maintenance pressure and operating costs of the equipment.
Softened water equipment has strong adaptability to high-hardness water sources. After one softening, the residual hardness of the water can be controlled at a very low level, effectively ensuring continuous and stable softened water output and meeting the continuous and stable water demand. In addition, the equipment is fully automatic operation control and does not require special personnel to be on duty. It only requires manual salt addition on a regular basis, which greatly saves maintenance costs and human resources.
In addition, softened water equipment is highly effective in improving thermal efficiency, reducing energy consumption and saving energy, and also plays a positive role in promoting environmental protection and corporate economic benefits. Easy operation and easy management are another great advantages of softened water equipment. The equipment is highly automated and meets the requirements of modern industrial production. It also makes the management of the equipment more convenient and effectively reduces the difficulty of operation. All in all, water softening equipment has become an indispensable member of water treatment equipment with so many advantages.
Main components of softened water equipment
Control valve: The control valve is the core part of the softening equipment. It mainly controls the working status of the softening equipment, such as normal operation, backwashing, salt absorption, slow washing, fast washing and regeneration. Fully automatic control valves are simpler to operate, cost-effective and efficient.
Resin tank: The resin tank is filled with ion exchange resin and is the main working part of the softening equipment. When hard water passes through the resin tank, the sodium ions in the resin exchange with the calcium and magnesium ions in the water, thereby softening the water.
Resin: Resin is the medium for ion exchange and generally needs to be replaced every 2-3 years.
Salt box: The salt box mainly stores salt used for ion exchange, and is used to regenerate resin by dissolving the brine.
Industrial salt: Industrial salt plays a core role in the regeneration stage. It removes calcium and magnesium ions from the resin through ion exchange with calcium and magnesium ions, restoring the softening function of the resin.
How to judge whether the equipment needs to add backwash and regeneration
Decrease in equipment efficiency: If you notice a significant decrease in equipment efficiency, such as reduced water flow, reduced water pressure, or an increase in hard water indicators, this may mean that the equipment needs to be backflushed and regenerated.
Monitor the quality of the water coming out of the equipment: Check the hardness of the water coming out of the equipment regularly. If the water hardness continues to rise beyond your water quality requirements, the frequency of backflushing and regeneration will need to be increased.
Physical damage to the equipment: If you see obvious wear or damage to the equipment, such as rusted pipes, broken resin particles, etc., this may require you to increase the frequency of backwashing to maintain normal operation of the equipment.
Observe the operating status of the equipment: such as operating noise, vibration, heat, etc. If it is obviously abnormal, it may be necessary to increase the frequency of backwash and regeneration.
Based on the manufacturer's recommendations: Equipment manufacturers usually provide recommendations for routine maintenance and backwashing of the equipment. You can refer to the manufacturer's recommendations to decide whether you need to increase the frequency.
Overall, increasing the frequency of equipment backflushing and regeneration can help prevent equipment efficiency loss, line blockage and can extend the equipment life cycle. Of course, excessive backwashing and regeneration may also cause equipment damage, so timely adjustments need to be made based on the actual operating status of the equipment and the manufacturer's recommendations.
