Biological swimming pond Down Flow

• No chlorine.

• Clear and healthy water.

• Low maintenance.

• Complete biological purification.

• Little use of technology.

• Low installation costs.

The most naturally purified swimming pool! Purification is left entirely to biological processes, the pond pump being the only technology necessary.

A sleekly shaped pool with clear and clean swimming water, part of which is set up as a helophyte filter. Nature mostly does the work here.

How Down-Flow works

The pond pump provides circulation and moves floating debris into the helophyte filter and settles. Aquatic plants, lava and bacteria carry out the natural purification process, which is boosted by aeration. The purified water is pumped back into the pond via injectors.

The cost of technology is low with this system but, on the other hand, the helophyte filter must be somewhat larger to ensure good purification.

One area of concern is maintenance, which does take a bit more time. With the installation of a UV-C clarifier, clear water is always ensured.
