Seawater Self-Cleaning Filter

Seawater Self-Cleaning Filter is a fully automatic comprehensive water treatment equipment with multiple functions developed on the basis of intelligent differential pressure filtration machines. It achieves a filtration accuracy of up to 10 microns, utilizing high-strength 2507 duplex stainless steel sintered membranes. It requires no filter element replacement, ensures thorough and dead-angle-free cleaning, and operates automatically with self-backwashing and self-discharging functions. The system operates safely and reliably, is easy to maintain, and has low operating costs. It can be installed vertically or horizontally depending on the site conditions.

Installation Requirements:

1. The filter must be installed at the outlet of the pump, and a check valve must be installed at the outlet of the filter to prevent sudden backpressure caused by water stoppage, which could damage the filter screen.

2. The pipeline network for equipment installation should ensure stable pressure and operate within the designed pressure range of the equipment.

3. The equipment should be installed horizontally, and the discharge outlet must not face upward (if upward installation is necessary, a discharge pump must be added). Minimize the use of elbows during installation to ensure smooth drainage.

4. A bypass valve should be installed between the inlet and outlet of the filter for use during system malfunctions or maintenance.

5. Pressure gauges must be installed on the inlet and outlet pipelines of the equipment to monitor system operating pressure and pressure loss.

6. A sampling and venting valve should be installed on the outlet pipeline of the equipment to facilitate sampling of filtered water during debugging and venting the equipment before long-term shutdown.

7. A maintenance space of 1 meter should be reserved around the equipment during installation.

Product Features:

Compared to other similar filters, the Qinhuang Haiwo brand seawater filter mainly has the following features:

1. The Qinhuang Haiwo brand seawater filter uses high-precision, high-strength 2507 duplex stainless steel (or alloy) composite screens. Through high-pressure backwashing at 1.7-2.0 MPa, the filter screen is cleaned efficiently and thoroughly, fully restoring its initial state.

2. The seawater backwashing filter has an automatic retrieval function, which automatically performs discharge and high-pressure backwashing based on retrieved data. It can handle unstable water quality fluctuations, operates fully automatically, and requires no manual intervention.

3. The control system is highly responsive and precise, featuring multiple setting functions such as differential pressure, time, and manual modes. It allows flexible adjustment of backwashing differential pressure or time settings according to different water sources and filtration accuracy requirements.

4. Backwashing does not interrupt normal water production, ensuring continuous operation with stability and reliability.

5. The backwashing process is short, with backwash water consumption accounting for only 0.001~0.002% of normal water production, saving water, electricity, and energy.

6. The structural design is compact and rational, with few vulnerable parts and no consumables. It has low operating and maintenance costs and is simple to operate and manage.

7. It can be installed vertically or horizontally based on site conditions, offering flexibility and convenience.
