Sand Filters & Multi Media Filters For water and waste water Treatment
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.

The size of each filter, the number of filters required, and the type of filter media used
depend upon
how small a solid needs to be removed,
how dirty the water is,
how the water will be used once it is filtered,
and the source of backwash water needed to clean the filters.
Application:
Widely used in electricity, electronics, beverages, water, petroleum, chemical, metallurgy, textile, paper,
food, swimming pools, municipal engineering and other process water, domestic water, drinking water, recycled water and wastewater pre-treatment areas.
