In our daily life and industrial production, water plays a vital role. However, untreated hard water often brings us many troubles. Fortunately, the emergence of softening water equipment has solved the hard water problem for us and opened up a new water experience.
1. The problem of hard water
Hard water is water containing more calcium and magnesium ions. In our lives, the problems caused by hard water are everywhere.
First, in terms of household water use, hard water will form scale in pipes, faucets, water heaters and other equipment. As time goes by, the scale continues to accumulate, which will not only reduce the service life of the equipment, but also increase energy consumption. For example, the scale in the water heater will reduce the heating efficiency, make the heating time longer, and increase the power consumption. At the same time, the scale on the faucet and shower will affect the size and uniformity of the water flow, which will bring inconvenience to our daily washing.
Secondly, hard water will greatly reduce the effect of detergent when washing clothes. Because calcium and magnesium ions combine with the ingredients in the detergent, it will make it difficult for the detergent to fully play its role, the clothes will not be washed clean, and even yellowing and hardening will occur. In addition, hard water can also cause damage to our skin and hair. After taking a bath with hard water, the skin may become dry and itchy, and the hair will lose its luster and become rough.
In industrial production, the harm of hard water is even more serious. Hard water will form a large amount of scale in equipment such as boilers and heat exchangers, reduce heat transfer efficiency, increase energy consumption, and may even cause safety accidents. In some industrial production processes, hard water will also affect the quality and performance of products. For example, in the textile printing and dyeing industry, hard water will cause uneven dyeing of fabrics, affecting the appearance and quality of products.
2. Working principle of softening water equipment
Softening water equipment is a kind of equipment specially used to remove calcium and magnesium ions in water and reduce the hardness of water. Its working principles are mainly as follows:
Ion exchange method
Ion exchange method is one of the most commonly used methods for softening water. The softening water equipment is equipped with ion exchange resin. When hard water containing calcium and magnesium ions passes through the resin, the sodium ions in the resin will exchange with the calcium and magnesium ions in the water, thereby adsorbing the calcium and magnesium ions on the resin, releasing sodium ions, and reducing the hardness of the water. When the sodium ions in the resin are exhausted, the calcium and magnesium ions in the resin need to be removed through the regeneration process to restore the exchange capacity of the resin. The regeneration process is usually carried out with brine, and the sodium ions in the brine will exchange with the calcium and magnesium ions in the resin, so that the resin regains its exchange capacity.
Reverse Osmosis
Reverse Osmosis is a method of water treatment using a semipermeable membrane. In the softening water equipment, the reverse osmosis membrane can effectively remove various impurities in the water, including calcium and magnesium ions. When hard water containing calcium and magnesium ions passes through the reverse osmosis membrane, due to the very small pore size of the reverse osmosis membrane, only water molecules can pass through, while impurities such as calcium and magnesium ions are blocked on one side of the membrane, thereby softening the water. The reverse osmosis method has a very good effect on softening water, but the equipment cost is high and the operation and maintenance are also complicated.
Electrodialysis
Electrodialysis is a method of water treatment using an electric field. In the softening water equipment, the electrodialysis membrane can separate the anions and cations in the water, thereby softening the water. When hard water containing calcium and magnesium ions passes through the electrodialysis membrane, under the action of the electric field, the cations in the water will move to the cathode and the anions will move to the anode. By selecting a suitable electrodialysis membrane, cations such as calcium and magnesium ions can be blocked on one side of the membrane, while anions and water molecules can pass through the membrane, thereby softening the water. The electrodialysis method has a good effect in softening water, but the equipment cost is high and the operation and maintenance are relatively complicated.
3. Advantages of softening water equipment
Extend the service life of equipment
Softening water equipment can effectively remove calcium and magnesium ions in water and prevent the formation of scale, thereby extending the service life of equipment such as pipes, faucets, water heaters, and boilers. Especially in industrial production, the use of softened water can reduce the maintenance and replacement costs of equipment and improve production efficiency.
Save energy
Since softened water does not form scale in the equipment, it can improve heat transfer efficiency and reduce energy consumption. For example, using softened water in a water heater can shorten the heating time and reduce power consumption; using softened water in a boiler can increase steam production and reduce fuel consumption.
Improve washing effect
Softened water can make detergents fully play their role and improve washing effect. When washing clothes with softened water, clothes are cleaner, softer and more colorful. At the same time, softened water can also reduce the amount of detergent used and reduce washing costs.
Protect skin and hair
Softened water is gentler on skin and hair, and will not make the skin dry or itchy, nor will it make the hair lose its luster or become rough. Bathing and washing hair with softened water can make our skin and hair healthier.
Suitable for various occasions
Softened water equipment can be widely used in various occasions such as homes, hotels, hospitals, schools, factories, etc. Whether it is domestic water or industrial water, it can be effectively treated by softening water equipment to meet the needs of different users.
IV. Selection and installation of softened water equipment
