Basic Functions

Remove suspended particles, sediment, and impurities from water or low-viscosity liquids, such as sand, silt, rust or other solid particles pollutants.

By removing various impurities in water, clearer water can be produced to meet the needs of high water quality standards, such as industrial processes, municipal water supply, residential water treatment, etc.

Protect downstream equipment, such as preventing blockage, wear or delaying scaling, etc.

Ensure the continuous and efficient operation of downstream equipment and extend their service life.

Provide uninterrupted filtering, eliminating the need for regular maintenance.

Reduce downtime, and significantly reduce the operation and maintenance costs of instruments.

After backwashing, the particles accumulated by filter media are removed, improving the utilization of filter media and preventing blockage, thus extending their service life and effectiveness.

The automatic control system of backwash filter can start backwash process according to the preset conditions, which improves the reliability and efficiency of filtration system.

Application

Automatic backwash filer can effectively filter out solid particle contaminants from water and low viscosity liquids (such as rolling emulsion, etc.), so that the liquid cleanliness can meet the system operation and downstream process requirements and protect the downstream key equipment. As a result, automatic backwash filers are widely used in the following industries.

Oil & gas. Injection well water filtration; act as a pre-filter for hydrocracking, hydrogenation modification, hydrorefining and hydrodesulfurization reactor to prevent the catalyst bed from clogging;

Metallurgy. Rolling mill coolant filtration;

Marine filtration system. Seawater desalination filtration; ballast water filtration;

Water treatment. Boiler supply water filtration;

Pulp & paper. Starch slurry filtration; paper making water filtration.
