Filter options for your swimming pool in France -  Differences between
standard pleated cartridge filter, diatomaceous earth and sand filtration and
NEW GLASS MEDIA

1. Pleated Cartridge Pool Filtration -  This is used with the wall panel Azure Hydro-Kit
International swimming pool.  Cartridge filtration has been in use for some time, and is widely
considered to be the most user friendly.  It  is both easy to use and highly effective.  It is
therefore very suitable for holiday let  in France, where the holiday makers may have little
knowledge of swimming pool maintenance, nor want to be bothered with too much effort to
ensure the pool water quality is maintained.  The water clarity with pleated cartridge filtration
is very good. Filtration with a cartridge ranges from 10 to 20 microns.  As the water passes
through the cartridge pleats, dirt is captured on the pleats.  The cartridges are easily
removed and cleaned with a garden hose.  This needs to be done approx once per week,
depending on pool usage and weather.  Although there are several filter options for your
swimming pool in France, this is probably one of the easiest for maintenance with effective
filtration, although cleaning out the filters can become tiresome.

2. Diatomaceous Earth Pool Filtration - Diatomaceous earth swimming pool filtration
provides excellent water clarity as it removes smaller particles than pleated cartridges.
Diatomaceous earth is composed of a porous powder with tiny openings - under a microscope
its appearance is similar to a sponge.  This means that even very small particles are trapped
on the first flush through the filtration, which ranges from 1 to 3 microns.  Maintenance,
however, is somewhat more involved, requiring backwashing and topping up of the
diatomaceous earth. The whole filtration unit must be completely taken apart and cleaned at
least once during the season. Diatomaceous Earth is also the more expensive option.

3. Sand Pool Filtration - This options is available with the Classique Hydro-Kit International
pool, it can also be incorporated with the Azure if preferred and with all Matrix pools.  Water is
pushed through a bed of filter sand and removed through a set of tubes at the bottom. The
filter area of a sand filter is equal to the area of the filter itself. For example, a 24” filter will
have 3.14 sqft of filter area. Only the top 1” of sand is actually used to filter the water. The
principle behind this filtration is that water is pushed through the sand, somewhat like an
espresso machine. Dirty water goes in the top and clean water exits out the bottom.  As the
sand becomes contaminated with debris from the  swimming pool, the pressure increases on
the filter and the water flow drops. In order to clean the unit, it is run in reverse and the waste
water is dumped; this is known as “backwashing”. Once the backwashing is complete, you
move to the rinse mode and this repacks the sand. After this,  change  back to filter mode.
This has to be done manually every few weeks.  When the sand  becomes really dirty, it is
easily and inexpensively replaced. In terms of particle size filtered out, sand is the least
effective method – it can allow smaller particles to pass back into the pool. However, it is by
far the easiest method for the user.

NEW  - GLASS MEDIA -
Sand filtration is dead,
but your Sand Filter may not be!

This media has been in use in the USA for 14 years but is new to France.
It filters out far smaller particles than sand, or cartridge and is far easier to use than
diatomaceous earth.
An average sand filter can catch particles as small as 100 microns.
A good cartridge filter can catch particles as small as 40 microns.

NB Dead skin and blood cells are smaller than 9 microns.

















Glass Media™  is an environmental and health technology from  ECOsmarte®.  This media
can be adapted to any sand pool filtration tank once the sand has been removed.


A chlorine or ECOsmarte pool will have never looked so good. Backwash at the six to eight
week window if the gauge has not moved as the glass uses the entire bed depth to load
contaminant. The pool will be crystal clear.   
The glass is machined like sugar, sterilized and 100 per cent recycled material.





























Glass Media has a 9 year life, Sand 3 years, DE 2 months


Zeolite is the generic name for a group of 30 minerals, all occurring in volcanic rock.  Zeolite
has a porous structure. The pores taper enabling filtration between the grains and also in the
pores.  It is sodium activated which enhances its natural propensity to exchange ammonia
ions for harmless sodium ions.  Zeolite is obtained from non sustainable supplies.





As can be seen, there are several filter options for swimming pools in France.  If you have any

Media™ pool filtration is changed only every 9 years
Glass Media™ is non hazardous
Sand pool filtration does not filter out small particles - Glass Media™
filters out very small particles even dead skin and blood cells.
Glass Media™ cleans easily and uses 25% less water to complete the
backwash, it also requires less frequent backwashing than sand.
Glass Media™ will lower consumption of chlorine and coagulants
Glass Media™ is made from recycled glass
