Self Backwashing Filter

Self Backwashing Filter

A self backwashing filter is a filtering device that intercepts impurities in a fluid (liquid or gas) through a filter. When the set pressure difference or time conditions are reached, it can automatically use reverse water flow to flush the filter to remove impurities attached to the filter, thereby continuously maintaining the filtering function without the need for frequent manual disassembly and cleaning.

Product advantages


1. Automatic and efficient operation: It can automatically trigger the backwashing procedure according to the pressure difference or time, without frequent manual intervention and cleaning, and can filter continuously and stably, greatly improving work efficiency and reducing labor costs.


2. Water and energy saving: Backwashing consumes less water, generally not exceeding 1-3% of the total flow; and the pressure loss during the filtration process is small, the energy consumption is low, and long-term use can effectively reduce the operating cost.


3. Long-lasting and stable filtration effect: Through backwashing, impurities on the filter net are effectively removed, and high filtration accuracy and good filtration performance are continuously maintained, the service life of the filter net is extended, and the water quality requirements of the back-end water use or process flow are guaranteed.

 

 

Scope of use

Industrial field: used in chemical, electronic and other industries to treat process water, cooling water, papermaking white water, etc., to prevent pipeline equipment from clogging and protect equipment.
Agricultural field: used for irrigation of farmland, orchards, and greenhouses, to filter water sources, prevent nozzles and drippers from clogging, and improve irrigation quality and efficiency.
Municipal and life fields: used for urban water supply pretreatment to improve water quality; used for garden irrigation, swimming pool water circulation, community secondary water supply filtration and reclaimed water reuse to meet the needs of domestic water filtration.

FAQ

Q: What are the core advantages of self backwashing filter? ​
A: Automatic backwashing, no need for frequent manual cleaning; low water consumption for backwashing (<3% of total flow), energy saving and water saving; optional filtration accuracy of 10-3000 microns, adapting to multiple scene requirements.


Q: Does it support customized requirements?
A: Customized filtration solutions can be customized according to customers' special flow, accuracy, installation space and other requirements.


Q: How to choose a model for agricultural irrigation? ​
A: Select the corresponding flow and filtration accuracy model according to the impurity content of the water source and the scale of irrigation, effectively filter river water and groundwater, and avoid nozzle clogging. ​


Q: What are the trigger conditions for backwashing? ​
A: When the preset pressure difference (0.5-1.0 bar) is reached or the time interval is set, the backwashing program is automatically started to maintain efficient filtration.
