How does a drum filter work?

The filter consists mainly of a tank in which is housed a rotating drum: this drum is coated with a filter membrane of 63 microns (0.063 mm) on its periphery.

The dirty water coming from the basin is directed inside the drum and, to leave this filter, the water must pass through the filtering membrane.

The water in the basin, which is free of particles, comes out of the filter and is directed to biological filtration.

As the dirty water passes through the drum, the particles settle by obstructing the small holes in the membrane, which gradually clogs.

The passage of the water is braked, which causes a difference in level between the downstream and the upstream of the sieve.

At this time, the detection system starts a cleaning cycle of the drum. From this moment, the drum rotates very slowly and the nozzles arranged on the upper part (outer side of the drum) project jets of water on the filter membrane: under the pressure of the water, the smallest dirt are expelled from the filter membrane.

This dirt is collected in a gutter and directed to the sewer. The upstream / downstream water level is restored until the next cycle.

This cleaning is minimalist type: it intervenes only when it is necessary.


They are numerous and the first is obvious: a good filtration is based on the principle of removing as quickly as possible a maximum of particles and extract them from the pond water so that they can no longer harm.

A "normal" filter can only retain what it can ... and the waste it retains is degraded in the water. With a drum, this is not the case, the biological filtration is less solicited, which in many cases can reduce its volume.

Second big advantage: provided you have a reasonable UV power, the water is clear all year round. Without problems!

Third advantage: completed the chore cleaning of the prefilter grille or brushes, a drum filter is self-cleaning. Let's be honest, this filter still requires a minimum of attention because it is a machine, and therefore some minor interventions are expected, but absolutely nothing binding.

Finally, each brand, each model has its particularities: it's up to you to determine the exact type of filter you need.

Pumping or gravity mode, stainless steel or polypropylene, with or without biological filter? These are the first criteria of choice but the most important is its size. Remember that a filter is never too big: the rinsing frequency will be comfortable (3 to 4 rinses per hour in summer for a dozen per day in winter).

On the other hand, a filter that is too small will consume more water because it will have to rinse more often. We are at your disposal to guide you in your choice.

The price of the transport of this article can not be reasonably calculated in advance because of the numerous variables: location, weight, volume, order of additional articles, possible delivery etc.

Rather than applying a package that is often very penalizing, we prefer to calculate the price, case by case.
