Brush Type Self-cleaning Filter for Water Treatment

Product Introduction

The brush type self-cleaning filter is a highly efficient filtration system designed for continuous online filtration. It effectively removes suspended solids, particles, and debris from various water systems, ensuring a steady and clean water supply. With a motor-driven brush mechanism, this filter cleans the filtration element without interrupting the ongoing filtration process.

Working Principle

The filtration process begins as water enters the filter housing and passes through the filter element. Suspended particles and debris are trapped on the inner surface of the filter element, allowing only clean water to exit through the outlet. Over time, as impurities accumulate, the differential pressure increases, signaling the system to initiate self-cleaning. The motor-driven brush mechanism then scrubs the filter element, dislodging trapped particles, which are subsequently discharged through a drain valve. This ensures continuous filtration without manual intervention.

Material Composition

Each component of the brush type self-cleaning filter is made from high-quality, durable materials to ensure longevity and corrosion resistance:

• Filter Housing: Stainless Steel (304/316L) or Carbon Steel with anti-corrosion coating

• Filter Element: Stainless Steel Mesh (SS304/SS316L)

• Brush Mechanism: Nylon or Stainless Steel Brushes

• Motor & Drive System: High-performance, waterproof electric motor

• Control System: PLC-based automatic control system for monitoring and operation

Applications

The brush type self-cleaning filter is widely used across various industries due to its efficient and automated cleaning capabilities. Some of its primary applications include:

• Agricultural Irrigation: Ensuring clean water supply for crops

• Raw Water Treatment: Removing suspended solids before further purification

• Industrial Circulating Water Filtration: Preventing system clogging and extending equipment lifespan

• Cooling Water Treatment: Maintaining efficient heat exchange and reducing maintenance costs

• Paper & Plastic Industry: Removing fine particles from water used in manufacturing processes

• Power Plants: Enhancing cooling tower and boiler water quality

Key Selection Parameters

To choose the right brush type self-cleaning filter, consider the following parameters:

1. Flow Rate: Measured in cubic meters per hour (m3/h), determines the filter size needed.

2. Filtration Precision: Ranges from 50 to 5000 microns; select based on application needs.

3. Operating Pressure: Ensure compatibility with system pressure requirements.

4. Filter Housing Material: Choose between stainless steel (SS304/SS316L) or coated carbon steel based on environmental      conditions.

5. Motor Power & Voltage: Confirm compatibility with available power supply.

6. Connection Type & Size: Ensure correct  inlet/outlet flange or threaded connections.

7. Control System: Choose between manual, time-based, or differential pressure-based cleaning activation.

8. Environmental Conditions: Consider temperature and chemical exposure factors.

FAQ

1. How does the brush type self-cleaning filter work?
        It uses a motor-driven brush to clean the filter element automatically when the pressure drop reaches a preset value, ensuring uninterrupted filtration.

2. What materials are used for the filter element?
        The filter element is typically made of stainless steel mesh (SS304 or SS316L) for durability and corrosion resistance.

3. Can the filter operate in high-pressure systems?
        Yes, the filter can be designed to withstand high operating pressures, but selection should be based on system requirements.

4. Is manual cleaning required?
        No, the filter operates automatically, significantly reducing manual maintenance requirements.

5. What is the typical lifespan of the filter element?
        With proper maintenance, stainless steel filter elements can last several years, depending on operating conditions.

6. Can the filtration precision be customized?
        Yes, filtration precision can be customized from 50 to 5000 microns based on application needs.

7. Is it suitable for seawater filtration?
        Yes, when constructed with corrosion-resistant materials such as SS316L, it is suitable for seawater applications.

8. How do I determine the right filter size for my system?
        The right size depends on flow rate, pressure, and the level of impurities in the water. Consulting with the manufacturer is recommended for optimal selection.
