Self-cleaning Filter

It is a new type of filtration system developed by our company with imported advanced technology. It is mainly designed to address the problem that fine impurities and suspended particles in processes such as petroleum, chemical industry and water treatment cannot be effectively removed by traditional filtration methods, especially the inability to clean online. Adopting a special filtration method, it can effectively remove insoluble substances in the system and other foreign matters introduced during manufacturing and processing.

Raw material flowing in from the inlet passes through the filter elements from outside to inside, where impurities are intercepted outside the filter elements, and the purified material is discharged from the clean cavity through the outlet. When the pressure difference between the inlet and outlet reaches the set value, each filter is cleaned in groups: the inlet and outlet valves of one group are closed, the blowdown valve and backwash valve are opened to perform reverse cleaning on the filter elements. After cleaning, it switches to the next group of filters for cleaning. The entire flushing process does not affect the normal filtration of the system, and the backwashing is convenient and quick. The whole system can be operated manually for backwashing or automatically through the control cabinet.

• Simple and reliable structure.

• Non-contact cleaning: particles will not be squeezed out of the filter elements, providing excellent impurity removal effect.

• Stable low pressure difference (less than 0.015MPa) is maintained during cleaning and blowdown.

• Extremely low working pressure requirement, minimum 30KPa.

• Wide flow range: single unit flow rate is 30-3000m³/h.

• Uninterrupted flow during self-cleaning.

• Easy installation and operation: novel structure, simple and flexible operation, energy-saving, efficient and closed operation with stable performance.

• Modular structure: the system is divided into clean cavity and dirty cavity by partitions, with several branch filter elements installed inside.

• High-quality materials: filter elements are made of 304/316L/super duplex stainless steel, and the shell is made of 304/316L/CS, ensuring corrosion resistance and durability.

• Convenient operation: supports both manual and automatic backwashing modes, adapting to different on-site management requirements.

• Domestic water supply and production process water supply filtration.

• Pretreatment for ultrafiltration, reverse osmosis, softening and ion exchange processes.

• Seawater purification for sea treasure seedling cultivation and water filtration for industrial seawater and freshwater aquaculture.

• Oilfield reinjection water filtration.

• Circulating cooling water filtration.
