Equipment features of Automatic Valveless Gravity Sand Filter
Dec 25,2023
An Automatic Valveless Gravity Sand Filter (AVGSF) is a type of water filtration system that operates without the use of valves：
1. Filter Bed: The AVGSF consists of a filter bed made up of layers of graded sand and gravel. The filter bed is designed to remove suspended particles and impurities from the water as it flows through.
2. Inlet Chamber: This is the entry point for water into the filter. It is designed to distribute the water evenly across the filter bed, ensuring uniform filtration.
3. Outlet Chamber: Once the water passes through the filter bed, it collects in the outlet chamber, from where it is discharged.
4. Backwashing Mechanism: AVGSFs are equipped with a backwashing mechanism to clean the filter bed periodically. This mechanism typically involves reversing the flow of water through the filter, dislodging trapped particles and flushing them out.
5. Air Scouring: Some AVGSFs incorporate air scouring to enhance the cleaning process. Air is injected into the filter bed during backwashing, creating agitation and improving particle removal.
6. Control Panel: AVGSFs often come with a control panel that allows for automated operation. It enables the scheduling of backwashing cycles, monitoring of pressure differentials, and adjustment of filtration parameters.
7. Pressure Gauges: These gauges measure the pressure differentials across the filter bed, indicating when backwashing is required.
8. Drainage System: AVGSFs have a drainage system to remove backwash water and any accumulated sediment or debris from the filter bed.
9. Filtrate Collection System: The AVGSF includes a system to collect the filtered water and direct it to the desired outlet or storage facility.
10. Structural Components: The AVGSF is typically housed in a robust structure made of materials such as concrete or steel, ensuring stability and durability.
