Silica Sand Filter
                
                  
Sand filters are used to remove suspended solids from water and wastewater. Because they    have one layer of filter media, sand filters remove only relatively large solids (normally    in the range of 40 micron and larger). The effective size of each granule of sand typically    varies from 0.35mm - 1.2mm. Larger granules yield coarser filtration. Finer granules yield  finer filtration.

Removing suspended solids smaller than 40 microns requires filters with either two or three  layers of filter media. These are referred to as dual-media filters or multi-media filters.  When sized properly and with the correct configuration of filter media, these filters can  remove suspended solids as small as 5 micron. Units are skid-mounted, factory assembled, wired, and tested, and delivered ready for installation. Piping, valves, filter media, pressure gauges and accessories are included  with filter systems. Solar power, media air scour, and rinse cycle are available as  options. Filter systems are engineered to require little maintenance.A separate source of  water supply or a pump for backwash are seldom needed.


The characteristics of sand filtration sand filter system
1. Manual or automatic control is available;
2.Simple, uniform and reliable water distributor.
3. Finished water collector is with strong working strength and long service life;
4. Easy installation. Just to connect the water inlet, water outlet and wastewater pipe for working.
 
5. Less water consumption for backwash: homogeneous quality filtration material to prolong the backwash circle and to reduce the water consumption greatly .
 
6. Backwash cycle is extended and the total backwash water consumption is greatly reduced; 
7. High backwash efficiency: An advanced water collector is used, ensuring efficient backwash effect to
  get clean water output.
