High Flow Automatic Backwash Filter

The High Flow Automatic Backwash Filter is a highly integrated automatic filtration system, which is mainly used to remove impurities such as suspended solids, particulate matter, colloidal substances and some microorganisms in water. The core of its design is not only to handle large flow of liquids, but also to remove impurities from the filter screen through the automatic backwash function without interrupting the production process, which greatly improves the filtration efficiency and the continuous operation of the system.

How it works

- Filter stage

1. Water flow dynamics. When working, the liquid to be filtered enters from the water inlet of the equipment and is evenly distributed to the filter unit through a carefully designed diversion system. These units are usually composed of high-quality filter screens, and the aperture of the filter screen is preset according to the application requirements.

2. Impurity interception. As the water flows through the filter, the impurities in it are effectively intercepted, and the clean water continues to flow to the system output for subsequent processing or reuse.

- Automatic backwash stage

1. Trigger mechanism. The system has a built-in intelligent monitoring device, usually including a differential pressure sensor and/or a time controller, which is used to monitor the pressure difference on both sides of the filter or start the backwash program at preset intervals.

2. Backwash start. Once the set conditions are reached, the system automatically closes the water inlet valve and opens the sewage valve at the same time to change the direction of water flow. At this time, a part of the clean water or additional high-pressure water is guided to the other side of the filter screen or the surface of the filter screen to reverse the water flow to impact the filter screen and wash away the accumulated impurities.

3. Filter cleaning. During the backwashing process, some high-end filters will use mechanical rotation (such as pig sideburns or stainless steel wire brushes) to further enhance the cleaning effect and ensure that the filter is thoroughly cleaned.

4. Restore operation. After cleaning, the system automatically switches back to the filtration mode, the water inlet valve is reopened, the sewage valve is closed, and the filtration process continues.

Parameters

Technical features

1. High efficiency and large capacity

The large filtration area design means a higher amount of pollution, which can maintain efficient filtration performance even under large flow rates and reduce the need for frequent maintenance.

2. Precise filtration

The filtration accuracy is adjustable, and users can choose the most suitable filtration grade according to their actual needs to ensure that the water quality meets specific standards.

3. High degree of automation

Through the intelligent control system, the automatic monitoring and response of various parameters such as pressure difference, time or flow rate is realized, with little need for manual intervention.

4. Energy-saving and water-saving

The backwashing process is short and accurate, consuming only a small amount of water, which greatly saves water and energy compared to traditional filtration equipment.

5. Stability and durability

Made of high-quality stainless steel and other corrosion-resistant materials to ensure long-term stable operation of the equipment and adapt to various harsh working conditions.

6. Flexibility and customization

According to different industries and application scenarios, the filter size, filtration accuracy, control method, etc. can be customized to meet specific needs.

Application field

Due to its high efficiency and reliability, the high flow automatic backwash filters are widely used in many fields, including but not limited to:

1. Industrial circulating water system: Provides clean circulating water for cooling towers, heat exchangers, etc., reducing scaling and corrosion.

2. Drinking water treatment: Ensure the safety of drinking water, remove suspended solids and some microorganisms.

3. Wastewater treatment: As a pretreatment step, larger particles in the water are removed to reduce the burden of subsequent treatment.

4. Agricultural irrigation: Filters impurities in water sources, protects sprinklers and irrigation systems, and improves irrigation efficiency.

5. Chemical and pharmaceutical industries: Ensure the purity of water and process fluids used in production to avoid contamination of products.

6. Power, metallurgy, and papermaking: In these high-water-consuming industries, it is used for the purification of cooling water and process water to prolong the life of equipment.

FAQ

1. Q: What is the function of a filter?

A: The main function of a filter is to remove solid particles, impurities, and harmful substances from liquids or gases, in order to achieve purification, clarification, and protection of equipment.

2. Q: How to choose a suitable filter?

A: When choosing a filter, factors such as the properties of the material being filtered (e.g., viscosity, temperature, corrosion), required filtration accuracy, processing capacity, operating pressure and medium, as well as the type, material, size, and installation method of the filter should be considered.

3. Q: What is the working principle of a filter?

A: The working principle of a filter mainly relies on physical screening, deep interception, absorption, or chemical reactions to remove impurities or harmful components from the material being filtered.

4. Q: How to maintain and care for a filter?

A: Maintenance of filters includes regular cleaning or replacement of filter elements, inspection of seals and fasteners, maintaining stable operating pressure, and avoiding overloading. Specific methods should be referenced from the filter's instruction manual and maintenance guides.

5. Q: What is the service life of a filter?

A: The service life of a filter depends on its working environment, processing volume, and filtration accuracy. Generally, when the filter's pressure drop reaches a certain value or the filtration effect decreases significantly, it needs to be replaced or cleaned.

6. Q: What should be paid attention to during filter installation?

A: During filter installation, attention should be paid to the directionality, ensuring that the fluid enters and exits from the correct ports. Also, the piping system should be cleaned before installation, and the filter should be securely fastened and sealed as required by the instructions.

7. Q: What is the replacement cycle for filters?

A: The replacement cycle for filters depends on their working conditions and filtration requirements, and is usually indicated by pressure difference indicators or timers. When the filter's pressure drop reaches the set value or the filtration effect decreases, it should be replaced in a timely manner.
