What is Backwash Water Filter?
Application: filtration of industrial water, seawater, food and pharmaceutical wastewater, circulating water, and filtration treatment of emulsion regeneration, waste oil, liquid raw materials, etc.
Backwash Water Filter is a precision filter that directly intercepts impurities by wedge wire screen, removes suspended solids and particulate matter in the water, reduces turbidity and dirt, bacteria, algae, rust, etc. to purify water quality and protect other equipment in the system. Due to the intelligent (PLC, PAC) design, the system can automatically identify the degree of impurity deposition and discharge the sewage.
It overcomes many shortcomings of traditional filtration products, such as small dirt holding capacity, easy to be blocked by dirt, filtering parts need to be removed and clean and unable to monitor the status of the filter. It has the ability to filter the raw water and automatically clean the filter element to discharge sewage.
In addition, the system provides uninterrupted water supply when cleaning and draining the sewage, which can monitor the working status of the filter with a high degree of automation. It covers the requirements of various filtration precisions from 10um to 3000um.
Working principle:
- The suspended particles trapped on the inner surface of the filter element gradually increase, the filter element is gradually blocked, resulting in a gradual increase in the pressure difference between the inner and outer sides of the filter element.
- When the set filtration time or the set pressure difference is reached, the controller sends out a backwash command to control the opening and closing of the drain valve, and uses the system's own pressure to realize the backwashing of the filter elements one by one.
- The suspended particles are discharged out of the filter, thereby restoring the filtering function of the filter element to the original intact state.
