Who wants to discover the new, has to take new ways

New techologies require research

We are always aspiring to work in close ccoperations with universities.In a close cooperation with the Hamburg University of Technology (TUHH), Intaqua AG has researched and developed the internationally patented “LooLoop-Process” – the closed loop processing of toilet waste water. The LooLoop-Process has been researched as a semi-technical (30 PE) plant and operated for almost 2,5 years. The treatment steps comprise

1. separation of solids, which are further worm-composted (Vermicomposting),
2. biological oxidation comprising nitrification of the liquids,
3. Ultrafiltration and
4. Ozonisation.

It could be shown, that after step 4 a clear, colour and odourless flushing water can be produced, which is sensually indistinguishable from normal water. During operation, the nutrients were increasingly concentrating in their oxidised forms (NO₃, SO₄, PO₄). The theoretical final molar nutrient concentrations (approximately equalling urine) could not be achieved. During the period of operation, no major process disturbances (membrane blockage, etc.) could have been observed. It could also been shown, that a black, humus-like compost can be hygienically safely produced from faecal matter and toilet paper. The optimal conditions for the composting process could have been shown.
