SAVE!
wiss bathroom company Laufen has collaborated with Austrian design studio EOOS, and one of the world’s leading water research institutes, Eawag, to develop a ground-breaking urine-separation toilet that opens a new chapter in sustainable wastewater management: Save!
S
This is based on years of research done for the Blue Diversion Toilet, developed by EOOS and the Eawag for the Bill and Melinda Gates Foundation’s ‘Reinvent the Toilet Challenge’. The key innovation in Save! is the ‘urine trap’, created by EOOS Design. It uses the hydrodynamic principle of the teapot effect to conduct the urine towards a concealed outlet using only surface tension. The intelligent design of the ceramic body ensures that the urine separation occurs irrespective of whether the toilet is used by a man, a woman or a child. Flushing water, which is discharged at a much higher rate and speed, runs down the regular siphon. The same applies to solids and toilet paper, which also fall into the siphon. Laufen has applied this principle to the wall-mounted WC and redesigned it with a urine channel to optimise its performance. Thanks to the perfect, almost imperceptible integration of the technology into the ceramic body, the WC achieves an elegant aesthetic and can therefore be integrated into sophisticated bathroom designs without any compromises.
Save! is the first urine-separation May 2020 ·
toilet that meets all industry standards. Rimless and wall-mounted, Save! means not having to compromise on comfort, nor on hygiene.
The raw material
There is much more potential in urine than people assume. It is worth considering urine as a valuable raw material. Save! takes a step towards sustainable recycling by ‘preserving’ the nutrients contained in urine and at the same time protecting the environment from harmful substances.
Preserving nutrients In addition to agricultural purposes, there are many more possible uses for the nutrients in this often-spurned liquid gold. British scientists have generated electricity with the help of the bacteria contained in urine – although the amount of electricity generated is low, it is still enough to power a mobile phone, for example.
Protection from harmful substances
But the aspect of wasting these nutrients is only one side of the coin. At present, the nutrients in urine often reach the natural waters directly, going through the wastewater treatment plants largely untreated. With a substantial amount of nutrients introduced into the natural waters as a result of over-fertilisation in agriculture, the waters become over- saturated, which in turn causes major problems for the environment. Nutrients become pollutants. Efforts to remove these pollutants
Smart sanitation for a sustainable future
Laufen takes a step towards sustainable wastewater management in a bold new collaborative move
Laufen Save! with innovative urine trap
standardised, pre-set flushing conditions and increases installation safety through a pre-assembled mounting cuff.
The waste stream separation occurs without any mechanical parts, using only surface tension and intelligent direction of the water flow and the shape of the ceramic. To develop and optimise the internal geometries, computational fluid dynamics simulations, developed by ETH Zurich, were used. Additionally, extensive practical flushing simulations were carried out in Laufen’s test laboratories.
Save! The vision
have made wastewater management infrastructure more expensive, complex and energy intensive. Laufen, along with their collaborators from EOOS and Eawag, made it their mission to find a solution to solve these challenges.
Save! The facts
Save! has been developed for the European market and has a patent pending. It is approved and complies with existing functional and connection standards. The odour trap in the urine siphon has a filling capacity of 75ml, ensuring water exchange with every flush and complying with urinal standards. The urine trap can be serviced or replaced without removing Save! from the wall. The yellow and black water pipes require installation in conjunction with a Laufen installation system, which guarantees
The installation of urine-separation toilets into hotels, public areas and residential developments will lead to sustainable and energy-saving wastewater management, seamlessly integrating the circular economy by efficiently treating the collected wastewater, recovering and recycling the preserved nutrients.
Global access
Laufen is committed to contributing towards the development of innovative technologies to solve this urgent problem, developing new solutions that will help save lives and improve sanitation conditions in developing countries.
