What is an Industrial Water Purifier
Industrial water purifier is a device specially used to purify industrial water. It removes impurities, microorganisms, dissolved solids and organic matter in water through a variety of purification technologies to provide high-quality water sources that meet the requirements of industrial production. Industrial water purifiers are widely used in industrial production processes that require high-purity water or special water quality requirements, such as electronic manufacturing, pharmaceuticals, food and beverages, electricity and chemical industries.
What are the Types of Industrial Water Purifiers?
5 types of industrial water purifiers:
1. Ultrafiltration water purifier,
2. Reverse osmosis water purifier,
3. Ion exchange water purifier,
4. UV disinfection water purifier,
5. Activated carbon water purifier.
1. Ultrafiltration water purifier:
Ultrafiltration water purifier uses ultrafiltration membrane technology to remove impurities such as suspended particles, colloids, bacteria and viruses in water, but retains minerals in water. Ultrafiltration technology has a high filtration accuracy and is suitable for industrial applications with high water quality requirements.
2. Reverse osmosis water purifier:
Reverse osmosis water purifier uses reverse osmosis membrane to almost completely remove dissolved solids, heavy metals, bacteria and viruses in water, providing extremely high purity water quality. Reverse osmosis technology is widely used in industries such as electronics manufacturing, pharmaceuticals, and food and beverages that require high purity water.
3. Ion exchange water purifier:
Ion exchange water purifier removes hardness ions (such as calcium and magnesium ions) in water through ion exchange resin to prevent scale formation. This technology is mainly used to soften water quality and is suitable for the treatment of boiler water and cooling water.
4. Ultraviolet disinfection water purifier:
Ultraviolet disinfection water purifier uses the strong bactericidal ability of UV-C light (wavelength of 200-280 nanometers) to kill bacteria, viruses and other microorganisms in water. Ultraviolet disinfection is often used to supplement other water purification technologies to ensure the sanitation and safety of water quality.
5. Activated carbon water purifier:
Activated carbon water purifier uses the adsorption capacity of activated carbon to remove organic matter, odor, residual chlorine and some heavy metals in water. Activated carbon is often used for pretreatment and terminal treatment to improve the taste and quality of water.
What is the working principle of industrial water purifier?
The working principle of industrial water purifier: pretreatment (mechanical filtration → sand filtration → activated carbon adsorption), main filtration process (ultrafiltration technology → reverse osmosis technology → ion exchange technology), post-treatment (ultraviolet disinfection → ozone disinfection → pH adjustment).
1. Pretreatment:
Pretreatment is the first step in the purification process of industrial water purifiers, aiming to remove large particles of impurities, suspended matter, silt and organic matter in the water and protect the subsequent filtration units. Pretreatment usually includes steps such as mechanical filtration, sand filtration and activated carbon adsorption.
● Mechanical filtration: intercept large particles of impurities in the water, such as silt, rust and suspended matter, through a filter screen or filter element. Commonly used mechanical filtration equipment includes bag filters, precision filters and multi-media filters.
● Sand filtration: use filter materials such as quartz sand to remove suspended matter and colloidal particles in the water. Sand filters are widely used in the pretreatment stage and have the advantages of fast filtration speed and large processing capacity.
● Activated carbon adsorption: adsorb organic matter, residual chlorine and odor in the water through the porous structure of activated carbon. Activated carbon filters are often used as key equipment for pretreatment and terminal treatment to improve water quality and taste.
2. Main filtration process:
After pretreatment, water enters the main filtration process, and suitable filtration technology is selected according to specific needs, such as ultrafiltration, reverse osmosis, ion exchange, etc.
● Ultrafiltration technology: Ultrafiltration membrane has a high filtration accuracy and can remove impurities such as suspended particles, colloids, bacteria and viruses in water. The ultrafiltration process does not change the mineral content in water and is suitable for industrial applications that need to retain minerals in water.
● Reverse osmosis technology: The pore size of the reverse osmosis membrane is extremely small, allowing only water molecules to pass through, and can effectively remove dissolved solids, heavy metals, bacteria and viruses in water. Reverse osmosis technology provides extremely high purity water quality and is widely used in industries with extremely high water quality requirements.
● Ion exchange technology: Ion exchange resin removes hardness ions (such as calcium and magnesium ions) in water through chemical reactions to soften water. This technology is mainly used for the treatment of boiler water and cooling water to prevent scale formation.
3. Post-treatment:
Post-treatment is an important step to ensure that the purified water quality meets specific requirements, usually including ultraviolet disinfection, ozone disinfection and pH adjustment.
● Ultraviolet disinfection: Use UV-C light to kill bacteria, viruses and other microorganisms in water to ensure the hygienic safety of water quality. Ultraviolet disinfection is often used to supplement other water purification technologies to provide ultimate microbial control.
● Ozone disinfection: Kill pathogenic microorganisms and remove organic pollutants in water through the strong oxidation effect of ozone. Ozone disinfection is highly efficient and environmentally friendly, but the ozone dosage needs to be controlled to avoid the production of by-products.
● pH adjustment: Adjust the pH value of water by adding acid or alkali to ensure that the water quality meets specific process requirements. pH adjustment is particularly important in some special applications, such as electronic manufacturing and chemical production.
What are the application scenarios of industrial water purifiers?
