Granular Multi-Media
Filters
ODIS granular multi-media
filters (M-M series) are suitable for a wide range of applications,
from the removal of colloidal suspensions to the treatment of
conditioned water, heavily polluted with organic matter, algae
and dirt. The several series of granular M-M filters feature
media layers of different heights. In each series, filters with
different diameters and types of filtering media are
available. Filter choice is based on the type and characteristics
of the application.
The following parameters should be considered:
- Flow rate
- Nature of solids
- Chemical characteristics of
the media
- Water source
- Required quality of treated
water
- Backwash water source

Applications
|
|
|
|
Treatment of drinking water, iron
and manganese separation from water and pretreatment for reverse
osmosis. |
|
|
SPA
|
Filtration of cooling tower water,
tertiary treatment of sewage reclamation for irrigation purposes,
filtration of swimming pool water, recycling of car-wash water
and more |
|
|
G
|
Filtration of cooling water in closed
cycle systems, filtration of industrial water and separation
of algae from water. |

Advantages
- Uniform filtration with even
raw water distribution throughout the filter bed
- Uniform evacuation of wash water
- Effective regeneration of the
filter bed due to the high rate of up-flow;
expansion and "fluidization" of the bed remove the accumulated
debris (solids captured during the filtration cycle)
- No channeling or formation of
mud balls
- Scouring and washing of each filtering
element to prevent and control biological growth in the filter
Odis
M-M Filter Features
All multi-media filters feature ODIS original
and uniquely effective design and construction.
- The filter is divided into two
chambers by a plate covered with conical diffusers for uniform
dispersal of the water and effective use of the entire media
volume (Model E400-400).
- Stable and highly efficient filtration
materials are used: crushed anthracite coal, crushed basalt
and natural quartz sand. For special applications, granular
active carbon, resins and different combinations of media are
available in accordance with customer requirements and ODIS
recommendations.
- For some applications, in accordance
with customer requirements and ODIS recommendations, the up-flow
water wash can be conjoined with an air scour operation.
