- One embodiment makes use of at least one PUR foam element. This is partially dipped in a low-viscosity resin in which magnetites are dissolved. It is preferably a resin of low viscosity, in particular epoxy resin, so that the pores of the polyurethane foam do not clog, so that the formed by the pores large vegetation surface remains.
- the magnetites are between 50-500 nm in size and can be of natural, chemical or biological origin.
- At least one magnetite-equipped polyurethane foam element is arranged in the cavity element, so that a magnetic field is formed.
- At least two PUR foam elements equipped with magnetites are arranged in the cavity element in such a way that a dipole can form.
- the magnetization of the PUR foam elements can take place, for example, such that the magnetites are present in the coating resin and the elements are arranged in such a way that a dipole is formed.
- the effect can also be achieved by the arrangement of one or more elements of magnetic material, or a combination of one or more ring, disc, rod, ball magnets done.
- Magnetic material elements may be combined with magnetite-containing foam elements, preferably using coated polyurethane foams.
- Both the PUR bodies and the listed magnetic elements may be coated with the following substances and substance groups:
- carbon nanotubes either as SWNT or MWNT. These may in turn be appropriately doped or coated.
- conductive, semiconducting and / or piezoelectric materials and photocatalytic materials are suitable for the production of coatings.
- COD chemical oxygen demand is a measure of all oxidizable substances present in the water with the help of the cavities so equipped
- the reduction of the COD value is directly related to the degradation of matter in the wastewater within 12 days between 82 - 87% could be reduced absolutely. Conventional methods usually require 20 days for this COD reduction.
- the cavity elements can also be used together with ionized gases in the fluid treatment.
