Backwash filters are widely used equipment in liquid processing and industrial applications, with the following characteristics and working principles:
Features:
Efficient filtration: The backwash filter can efficiently remove solid particles from the liquid, ensuring product quality and smooth progress of the process.
Automatic cleaning: This type of filter has an automatic cleaning function, reducing downtime and the need for manual maintenance. They will automatically perform backwashing operation at a certain time interval or when the pressure difference reaches a certain value, remove blocked filter material, and restore flow rate.
Saving maintenance costs: The automatic cleaning feature extends the service life of the filter, reduces maintenance costs, and makes it more cost-effective.
Industry application: Backwash filters are suitable for various liquids, including water, solution, oil, liquid food, and other liquids, making them widely used in different industries.
Customizability: Users can choose backwash filters of different sizes, materials, and filtration accuracy based on specific application needs.
Working principle:
The working principle of the backwash filter is based on reverse flow. The following is its workflow:
Filtration stage: When sewage or liquid passes through the filter, solid particles are filtered out and clean liquid flows out. At this point, the filter material or filter medium in the filter begins to accumulate particulate matter.
Cleaning stage: When the set time interval or pressure difference reaches a certain value, the filter starts the automatic backwash program. This usually involves reversing the flow of cleaning liquid (usually the liquid itself or other cleaning agents) through the filter to clean and flush away blocked solid particles.
Reuse: After cleaning, the filter returns to the filter stage and is ready to pass again. This cycle can be repeated to extend the service life of the filter.
The characteristics and working principle of backwash filters make them an ideal choice for handling fluids that require continuous and efficient filtration. They are widely used in fields such as water treatment, chemicals, food and beverage, pharmaceuticals, and provide reliable filtration solutions.
