What is an industrial reverse osmosis water filtration system?
Industrial reverse osmosis water filtration systems play an important role in modern industrial production, especially for industries with high requirements for water quality, such as electronic manufacturing, pharmaceuticals, food and beverage, and chemicals.
This article will explore in depth what an industrial reverse osmosis water filtration system is, its working principle, key components, application scenarios, and service life.
What is an industrial reverse osmosis water filtration system?
Industrial reverse osmosis (RO) water filtration system is a device that uses reverse osmosis membrane technology to remove impurities such as dissolved salts, organic matter, microorganisms, and heavy metals in water, providing a high-purity water source. Reverse osmosis technology applies high pressure to make water pass through a semipermeable membrane, filter out impurities, and achieve the purpose of purifying water quality. Industrial reverse osmosis systems are often used in industrial production processes that require ultrapure water or high-quality water.
What is the working principle of an industrial reverse osmosis water filtration system?
Reverse osmosis (RO) is a process that purifies water by applying reverse pressure to make water molecules pass through a semipermeable membrane, while impurities and dissolved solids are retained on the other side of the membrane. The main working principle of the reverse osmosis water filtration system includes the following steps: pretreatment → pressurization → reverse osmosis filtration → water production and concentrated water discharge → post-treatment.
1. Pretreatment:
● Mechanical filtration: remove large suspended solids and sediment in the water.
● Activated carbon adsorption: remove organic matter, residual chlorine and odor in the water.
● Softening treatment: remove calcium and magnesium ions in the water to prevent reverse osmosis membrane scaling.
2. Pressurization:
● Apply pressure through a high-pressure pump to pass water through the reverse osmosis membrane. The pressure is usually between 2 and 10 atmospheres, and the specific value depends on the inlet water quality and system design.
3. Reverse osmosis filtration:
● Reverse osmosis membrane: The semipermeable membrane is the core component of the reverse osmosis system, with a pore size of about 0.0001 microns, allowing only water molecules to pass through. The membrane is usually made of polyamide composite membrane with high efficiency filtration capacity.
4. Water production and concentrated water discharge:
● Water production: The purified water is collected for industrial production.
● Concentrated water: water with high concentration of impurities is discharged or recycled.
5. Post-treatment:
● Ultraviolet disinfection: ensure that microorganisms in the water are completely eliminated and the water quality is safe.
● pH adjustment: adjust the pH value of the produced water according to specific requirements to ensure that it is suitable for industrial use.
What are the key components of industrial reverse osmosis water filtration system?
The key components of industrial reverse osmosis water filtration system are: reverse osmosis membrane, high-pressure pump, pretreatment equipment, control system, pipelines and accessories.
1. Reverse osmosis membrane:
● The reverse osmosis membrane is the core component of the system and determines the efficiency and quality of filtration. Commonly used reverse osmosis membranes include roll membranes, tubular membranes and flat membranes.
2. High-pressure pump:
● The high-pressure pump provides the necessary pressure for the reverse osmosis process and is an important equipment to ensure that water passes through the membrane. The selection of the pump needs to consider factors such as water inlet, system pressure and energy consumption.
3. Pretreatment equipment:
● Including mechanical filters, activated carbon filters and softening equipment, etc., to ensure that the water quality entering the reverse osmosis membrane meets the requirements and extend the service life of the membrane.
4. Control system:
● Including pressure sensors, flow meters and automatic controllers, etc., real-time monitoring and adjustment of system operating parameters to ensure stable operation of the system.
5. Pipes and accessories:
● High-quality pipes and accessories are the basis for ensuring long-term stable operation of the system, and must have characteristics such as corrosion resistance and high pressure resistance.
