Introduce:

In the field of water resource treatment, reverse osmosis filter is an extremely critical and revolutionary device. It is widely used in industrial production, daily life, scientific research experiments and many other aspects due to its excellent filtering performance, playing an irreplaceable role in ensuring the quality and safety of water resources.

Principle of reverse osmosis filtration:

1. Basic principles

The core principle of reverse osmosis (RO) is based on the concept of osmotic pressure. Place solutions of different concentrations on both sides of a semi permeable membrane. In a natural state, the solvent (usually water) will permeate through the semi permeable membrane from the low concentration side to the high concentration side until the osmotic pressure on both sides reaches equilibrium. The reverse osmosis process applies a pressure greater than the osmotic pressure on the high concentration solution side, forcing the solvent to reverse osmosis, that is, flowing from the high concentration solution side through a semi permeable membrane to the low concentration solution side.

2.The mechanism of action of reverse osmosis membrane

The core component of a reverse osmosis filter is the reverse osmosis membrane. This type of membrane is usually made of polymer materials and has extremely small pore sizes, typically around 0.1-1 nanometers. These micropores allow only water molecules to pass through, while almost all impurities in water, such as dissolved salts (including sodium ions, chloride ions, calcium and magnesium ions, etc.), organic matter (such as pesticides, petrochemical products, etc.), colloids, microorganisms (bacteria, viruses, etc.), are intercepted.

The workflow of reverse osmosis filter:

The raw water first enters the raw water tank, and under the action of the raw water pump, it is transported to the multi-media filter for preliminary filtration to remove large particle impurities. Then, the water flows into the activated carbon filter to remove organic matter and residual chlorine. If the hardness of the raw water is high, it needs to be softened by a softener. After pre-treatment, the water enters the reverse osmosis host. Under the pressure of the high-pressure pump, the water passes through the reverse osmosis membrane module, and the water molecules in it pass through the reverse osmosis membrane to form pure water, which enters the pure water tank. The intercepted impurities and salts are discharged as concentrated water. Finally, pure water can be further processed by UV sterilizers and precision filters as needed before use.

Characteristics and advantages of reverse osmosis filters

1.Efficient filtering performance

Reverse osmosis filters can remove up to 95% -99% of impurities such as salt, organic matter, and microorganisms from water, producing pure water that can meet almost all application scenarios with extremely high water quality requirements.

For some difficult to treat pollutants, such as heavy metal ions (such as mercury, cadmium, lead, etc.), pesticide residues, polycyclic aromatic hydrocarbons, etc., reverse osmosis filters can also achieve very good removal effects.

2.Stable effluent quality

Once the reverse osmosis filter is debugged and operates normally, it can continuously and stably produce pure water that meets the predetermined quality standards, without being affected by fluctuations in raw water quality.

This stability is crucial for some industrial production processes that require extremely high water quality stability, such as electronic chip manufacturing, high-end pharmaceuticals, etc.

3. Easy to operate and highly automated

Modern reverse osmosis filters are typically equipped with advanced automation control systems. These systems can achieve functions such as automatic operation of equipment, automatic monitoring (such as monitoring parameters such as pressure, flow rate, water quality, etc.), and automatic flushing (such as regular flushing of reverse osmosis membranes).

Operators only need to perform simple monitoring and daily maintenance, greatly reducing the difficulty and workload of manual operations.

4.Small footprint

Compared with traditional water treatment equipment such as ion exchange and distillation, reverse osmosis filters have a smaller overall footprint.

This makes it easy to install and use in places with limited space, such as small water treatment stations in cities, local water treatment areas in factories, etc.

5. Environmentally friendly and pollution-free

During normal operation, the reverse osmosis filter does not require the addition of any other chemical agents except for a small amount of flocculants, fungicides, and other chemicals that may need to be added during the pretreatment process.

It does not produce chemical pollution, and the concentrated water can be recycled after appropriate treatment, which meets environmental protection requirements.

Application areas of reverse osmosis filters:

1. Industrial sector

electronics industry

In the electronics industry, especially in the manufacturing process of semiconductors and integrated circuits, there are extremely high requirements for water quality. Reverse osmosis filters can produce ultrapure water, ensuring the manufacturing quality and performance of electronic components.

Pharmaceutical industry

A large amount of high-purity water is required in the pharmaceutical process for the production, cleaning, and preparation of drugs. Reverse osmosis filters can effectively remove impurities and microorganisms from water, ensuring the safety and quality of pharmaceutical water.

Chemical industry

Many chemical production processes require the use of high-purity water as a reaction medium or cleaning water. Reverse osmosis filters can provide pure water that meets the requirements of chemical processes, improving the quality and yield of chemical products.

power industry

In thermal power plants, boiler feedwater needs to undergo strict treatment to prevent boiler scaling and corrosion. Reverse osmosis filters can remove salt and impurities from water, improving the safety and efficiency of boiler operation.

2.Daily life field

Household drinking water

Municipal tap water, groundwater, surface water, etc. can be converted into high-quality drinking water to remove various pollutants such as heavy metals, organic matter, bacteria, viruses, etc., improving the taste and safety of water.

Commercial direct drinking water

Reverse osmosis filters are widely used in direct drinking water systems in commercial places such as office buildings, shopping malls, and hotels, providing people with convenient and healthy drinking water.

3.Food processing field

Beverage production

In the process of beverage production, the quality of water directly affects the taste and quality of the beverage. Reverse osmosis filters can provide pure water sources and ensure the quality of beverages.

Dairy processing

For dairy processing, high-purity water is one of the key factors ensuring product quality and safety. Reverse osmosis filters can remove impurities and microorganisms from water, meeting the water demand for dairy processing.

4. Research and experimental field

Laboratory water

Various scientific experiments have different requirements for water purity, but in many high-precision experiments such as chemical analysis, biological experiments, materials science experiments, etc., high-purity water is needed. Reverse osmosis filters can provide laboratory with pure water that meets experimental requirements.

Summary:

As an efficient and reliable water treatment equipment, reverse osmosis filters play an extremely important role in many fields such as industrial production, daily life, and scientific research experiments. It has become one of the core equipment in the field of modern water treatment due to its efficient filtration performance, stable effluent quality, easy operation, high degree of automation, small footprint, and environmental friendliness. With the continuous innovation of membrane materials, the application of intelligent technology, the development of energy-saving technology, and the promotion of miniaturization and integration, the performance and application fields of reverse osmosis filters will continue to expand, providing more powerful technical support for solving global water shortage and pollution problems.
