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. UNTIL NOW......... 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.

Important pool filtration differences:-
 | Sand pool filtration require sand to be changed every 3 years - sand | |
| contains silica which is hazardous to whoever changes the sand, Glass 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. | ||
| Less Glass Media™ is required to fill the filter tank than sand. | |
| 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 | |
