Product Description

20TPH Quartz Sand Filter For Water Treatment Plant

Mechanical FRP/Carbon Steel 20T/H Quartz Sand Filter for Water Treatment Plant

Quartz sand filter. It is a pressure filter, the filter is filled using the refined quartz sand, from top to bottom when the water flows through the filter layer, suspended solids and pectin particles are removed, so that the water is turbid decreased.


Working Principle


  • Mechanical sand filter, also known as pressure filter, is an important part of the water pretreatment and water purification systerms. Mechanical sand filter packing is mainly used to reduce water turbidity, remove the water suspended particles, organic matter, colloidal particles, microorganisms, residual chlorine and some heavy metal ions.
  • The turbidity of raw water require less than 20 degrees, and it will up to 3 degrees when the filtration completed.



Mainly used in water treatment turbidity removal, softening, electrodialysis, the first stage reverse osmosis pretreatment it can also be used aspects of surface water and groundwater. Can effectively remove suspended solids, organic matter, colloid, such as silt.

It can be widely used in electronic power, petrochemical, metallurgy electroplating, paper textiles, pharmaceuticals, dialysis, food and beverages, drinking water, water for factories and enterprises, swimming pools and so on. To meet the needs of various industries liquid filtration.

This product can be divided into manual type and automatic type.

The Filtering Process
Filtering with media filters, also known as depth filtration, is done by filtering water through a thick layer of graded particles, called the filter bed. These particles can be sand, gravel or other granular materials. The filtration degree depends on the effective size of the bedding and the water velocity through the filter.

Raw water enters from the filter inlet (1) and percolates through the filter bed (2). Suspended materials come into contact and attach to the media particles. Clean water flows through the filtration nozzles (3) and out of the filter via the outlet valve (4).

The gradual dirt buildup in the filter bed causes an increase in the pressure differential across the filter and when it reaches its maximum design value, a cleaning process should be performed. In automatic media filter installations a pressure differential switch senses the pressure differential and when it reaches a preset value, the self cleaning process begins

The Cleaning Process
Cleaning is done by backwashing; pressurized water flows in reverse direction – from the nozzles upwards, causing suspension of the filter bed, thus releasing the suspended matter from the bedding. The dirt particles are then washed out of the filter through the back-flush valve. In automatic media filters installations the cleaning process is done by the system's controller. When the pressure differential switch senses that the differential pressure across the system reached a pre-set value, a signal is sent to the flushing controller and the self cleaning process begins.
