Suffer from blue-green algae and dirty surface water? Meet the Oxatur
Hearing the name, you might think it is something like a detergent, but think again… Meet the Oxatur, a floating ‘palace’ (here: float land) that cleans surface water 24/7 and with virtual no handling or maintenance. Smart people, the Dutch. The Oxatur is three way-system:
- From underneath water is pumped to the top of the device, where gravity and the shape of the Oxatur take over. Dispersed over the special formed and greater surface, the water gets enriched with oxygen.
- Just before the pumped-up water meets gravity, it runs through a tube with a solid PCC-coating (photo catalysis cleaning – http://en.wikipedia.org/wiki/Photocatalysis ) in which the sun and a catalyst speed up the degradation of: (micro-)pollutants, algae, bacteria and alcohols (http://en.wikipedia.org/wiki/Alcohols).
- As seen in 1) the Oxatur has to be a so-called float land, for optimal oxygen enrichment. But also this surface comes in handy for grasses to be grown upon that assimilate phosphor and nitrogen, two main unwanted fertilizers in surface water. Cut the grass after the growing season and you can use it as fertilizer (ideally way off the water body that is… ).
And energy, for the pumping and all? That comes from wind- and solar power.
Of course, there are limitations how much surface water can be handled by a single standard float land, and also in which season. But why not have two, or three or maybe ten of these palaces floating around? It all depends on the situation, size and dynamics of the filthy, smelly, greenish water body you want take care of.
By the way, Oxatur’s inventing and producing company is the very same as the one from the SolarBee, a solar powered ‘water mover’ that got quite a lot of news coverage in the USA and Canada a couple of years ago.
