| Zusammenfassung: | Green walls with greywater treatment capabilities can play a key role to close water cycles in growing cities worldwide. Most green wall systems for greywater treatment apply a similar process as in constructed wetlands, where the substrate acts as plant substrate and to treat the polluted water. A novel green wall system is in development that separates the plant layer from the greywater treatment, by introducing a setup similar to a trickling filter. In a first step, various commercial substrates were tested for their suitability in terms of treatment performance at two different hydraulic loading rates over a 10-week period, using synthetic greywater. Measured parameters for determining pollutant removal were turbidity, chemical oxygen demand (COD), and others over a treatment time of seven days, measuring concentrations at the beginning, after three days and at seven days. The first substrate, expanded shale, performed best, achieving removal rates up to 60% for COD, closely followed by the other two substrates, plastic Hel-x and foam carriers. Generally, most pollutants were removed within the first three days of treatment. Even though plastic Hel-x carriers were not as efficient in pollutant removal as expanded clay, the carrier will be used for planned pilot trials of the novel green wall system due to their lower weight. |
