What Is Water Purification Equipment?
Water purification equipment are equipment for producing highly purified water. They are sometimes simply referred to as pure water equipment.
Pure water is used when high purity is required for a particular application. Water purification equipment combines various technologies to purify water and remove impurities, microorganisms, and dissolved substances.
Water purification equipment is cost-effective in the long run because it eliminates the need to purchase and deliver water on a regular basis. This can lead to cost savings, especially in operations and industries that require large quantities of purified water. It can also reduce the use of containers, thus contributing to the reduction of waste and environmental impact.
Uses of Water Purification Equipment
Water purification systems are used in a variety of applications, including:
1. Pharmaceutical Industry
Pharmaceutical companies aim to produce high quality and safe pharmaceutical products. Pure water is often used in processes such as product preparation, washing, dissolution, and formulation adjustment.
Highly purified water is essential for dissolving the ingredients used as raw materials for pharmaceutical products. In the cleaning process, purified water is also used to keep water purification equipment and containers clean.
2. Electronic Device Manufacturing
Electronic device manufacturing involves the use of microscopic components and circuits. These components and circuits will not function properly if minute impurities are present. It is important to clean substrates and chips with pure water to remove impurities and dust.
In addition, since electronic equipment often generates heat, pure water is often used to dissipate the heat. This allows the equipment to operate efficiently while maintaining the proper temperature.
3. Power Plants
Steam turbine power plants use high-temperature, high-pressure steam to generate electricity. To produce steam, high-quality feed water is required. Water purification equipment removes impurities and dissolved substances from the water and provides high-quality water to feed the feedwater pumps.
In addition, deionized water is sometimes used as cooling water in nuclear power plants. High-quality cooling water is required to cool nuclear reactors. Therefore, water purification equipment is used in nuclear power plants to ensure that the cooling water is of high quality and stable.
Principle of Water Purification Equipment
The principle of operation and structure of water purification equipment differs depending on the type. However, they all share the use of physical separation and chemical adsorption to improve the purity of water.
Water purification equipment uses micropores or special membranes to physically isolate or separate impurities and microorganisms in the water. This removes impurities from the water and produces purified water.
In addition, impurities are often adsorbed to increase the purity of the water. In ion exchange, resins are used to remove or exchange dissolved ions. In activated carbon filters, for example, water is purified by adsorbing impurities and organic matter.
Types of Water Purification Equipment
There are various types of water purification equipment. The following are examples:
1. Reverse Osmosis
Reverse osmosis (RO) systems purify water using reverse osmosis (RO) membranes, which are generally used in combination with water purification filters, activated carbon filters, and ultraviolet sterilization equipment. They are suitable for a wide range of applications and are often used in pharmaceuticals, electronics manufacturing, and chemical analysis.
2. Distillation Equipment
Distillation equipment purifies water by evaporating and recondensing it. It removes impurities from the water and produces high quality pure water. Distillation units have been in use for a relatively long time and are used in laboratories and some industries.
Volatile impurities can be removed by discarding the first distillate. However, it is difficult to separate impurities that have close boiling points to water.
3. lon Exchange Equipment
An ion exchange device is a device that uses ion exchange resins to remove dissolved impurities in water. It often uses a mixture of cation and anion exchange resins. It is suitable for removing unwanted inorganic impurities.
However, the adsorption capacity of ion exchange resins is limited, so the impurity removal capacity gradually decreases. Therefore, it is important to record the time of use, water volume, etc. Some products can regenerate ion exchange resins by using hydrochloric acid or caustic soda.
