Self-cleaning Filter

Introduction

The automatic self-cleaning filter is a precision device that uses a filter screen to directly intercept impurities in the water to purify the water quality and protect the normal operation of other equipment in the system. Water enters the self-cleaning filter body from the water inlet. Because of the intelligent (PLC, PAC) design, the system can automatically identify the degree of impurity deposition and send a signal to the drain valve to automatically drain the filter.

The automatic self-cleaning filter overcomes many shortcomings of traditional filtration products such as small dirt holding capacity, easy to be blocked by dirt, the filter part needs to be disassembled and cleaned, and the filter status cannot be monitored. It can filter raw water and automatically clean and discharge the filter element. function. Moreover, the system provides uninterrupted water supply during cleaning and sewage discharge, and can monitor the working status of the filter, with a high degree of automation. Covering various filtration precision requirements from 50um to 5000um, we provide customers with various water filtration equipment.

Features

1. Simple design structure.

2. Short back-cleaning time, large flow rate, and small pressure loss (≤ 0.018MPa).

3. Self-cleaning control methods are divided into pressure difference, time and manual.

4. The filter can be connected to the DCS system.

5. High-precision filtration, stable effluent quality, and sewage water consumption <1%.

6. No need to replace the filter screen.

7. Long service life.

8. Applicable to different raw water quality and water requirements.

9. Few wearing parts, no consumables, low operating costs, and simple operation and management.

10. Automatic backwashing and continuous flow.
