Water Treatment Automatic Backwash Filter

The water treatment automatic backwash filter's design purpose is to effectively remove suspended solids, particulate matter, and reduce the turbidity of water, thereby purifying water quality and protecting other equipment in the system from damage such as dirt, algae, rust, etc. Serving as a kind of highly automated water treatment equipment, it is widely used in water supply systems, process water systems, industrial cooling water systems and other fields, especially in systems that require continuous and uninterrupted operation.

Component

The components of the water treatment automatic backwash filter include:

- Cylinder: Usually made of high-quality carbon steel or stainless steel, it acts as the main body of the filter to ensure strength and corrosion resistance.

- Stainless steel deed filter: A filter with a special structure that can efficiently intercept impurities.

- Water flow guide valve: Control the direction of water flow to achieve automatic backwash function.

- Differential pressure controller: Monitor the pressure difference before and after filtration, and trigger the backwash procedure when the pressure difference reaches the set value.

- Electric Control Box: Contains an automated control system (such as PLC) to automatically control the operation of the filter and the backwashing process according to preset parameters.

- Sewage Discharge Device: Automatically executes the sewage discharge action and discharges the intercepted impurities from the system.

Working principle

1. Filtration stage. The water flow enters the filter from the water inlet, intercepts impurities through the filter, and the clean water flows out through the filter.

2. Identify and start backwashing. The built-in intelligent control system (such as PLC or PAC) monitors the pressure difference at both ends of the filter through the differential pressure controller, and automatically starts the backwashing program when the pressure difference reaches the set threshold.

3. Backwash stage. Reverse the direction of water flow, use system water pressure or external power source to flush the filter, and discharge the trapped impurities from the sewage outlet.

4. Restore filtration. After the backwash is over, the water flow direction returns to normal and the filter starts working again.

Features and advantages

- Automatic operation. No manual intervention is required, and backwashing is automatically carried out according to water quality conditions, reducing maintenance costs.

- High efficiency. Can quickly remove impurities from the filter screen without affecting the operation of the system.

- Save Water. Backwashing processes are usually designed to recycle water and reduce water waste.

- Extend system life. Effectively protect subsequent equipment, such as pumps, heat exchangers, etc., to prevent clogging and corrosion.

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.
