Bjartur Swart, responsible for the STOWA for research into decentralized wastewater treatment, visited a play farm Den Scherpenberg in Rucphen, the Netherlands, together with a photographer. In 2019, Rietland installed an aerated constructed wetland, type Phytoair, for the treatment of the sanitary waste water from the toilets and the canteen. The filter is 45 m² in size and can process a maximum of approx. 5,000 liters per day. In quieter periods, the time the air blower runs is automatically adjusted to save energy.
Following the visit, the article below appeared in the magazine “For Info” of the STOWA.
A special feature of the system at Den Scherpenberg is that the drainage does not go to surface water, but to a willow filter that the owner installed himself. Here a large part of the purified water is evaporated and a part infiltrates into the soil.
