Plant-based purification systems
AQUANT-dsm and AQUANT-ibs

The series AQUANT-dsm and AQUANT-ibs are especially designed for the natural cleaning of sewage from residental buildings and they are tested and certificated by the DIBT [German Institute for Constructional Engineering].

Functionality

Sewage is initially passed though a prepurification process (size of the prepurification plant per inhabitant 0.5 m³ - 1.5 m³, as a general rule the prepurification plant should be implemented as multi-chamber shaft according to part 1 DIN 4261). After the release of removable components it then flows into the plant purification area. There it percolates through the sand and gravel which is rooted by reed plants and enriched with microorganisms in a vertical direction and is thereby cleaned.
After several days all-biologically cleaned water, free of germs is released by the plant, which under normal circumstances can be conducted or allowed to seep into a brook, a river or a polishing pond.
Reed plants form fast growing root extensions in the soil, several centimetres thick, these so called rhizomes constantly regenerate, dig up the soil and die after several years. Though this process new cavities are continually developing in the soil. Due to these special characteristics reed plants create a perfect habitat for microorganisms. The contamination of the sewage water produces energy-rich organic compounds, which are used by the microorganisms as food and so are broken down by them. The reed plants create the perfect living conditions where the microorganisms can thrive and do the actual cleaning, a perfect team!
In order to intensify the purifying effect, we are planning a bypass line ("small recirculation"). Whenever pumping takes place, a small amount of the cleaned sewage will be pumped back into the inflowing canal so that microorganisms that would otherwise be washed away will now get into the top layers of sand once again. This way, the whole system works rather stable and effective, since it adapts to new technical requirements rather easily.

The DIBT Certificate

AQUANT plant-based purification systems are proofed and certificated by the "Deutsches Institut für Bautechnik (DIBT)" [German Institute for Constructional Engineering].
