World water day March 22: experiment innovative waterless toilets in Paris

Note by moderator: A previous discussion thread about this innovation is available here on the forum:
forum.susana.org/106-user-interface-tech...-in-a-closed-circuit

+++++++++++

Come to Paris and experiment the WeCo Technology Recycling Blackwater from toilets into « New Water» developed with Caltech.
We will showcase WeCo Caltech technology on March 22nd from 12.30 to 5 pm.
See: www.en.weco-toilet.com/news/world-water-day-2019/
Come and visit us during World Water Day, March 22nd 2019 from 12.30 to 5 pm, to test and discover what innovative and sustainable flush toilets are about!

WeCo created the first eco-friendly, innovative and self-contained flush toilets. All excreta is recycled on-site into drinking quality treated water for flushing and watering green areas. We are developing the ecological toilets of the future for communities, off grid buildings. Together with Alstom, we are working on an industrial system ready to be connected to the public toilets of trains and other public places.
Our technology converts urine into water treated by electrochemical treatment: all bacteria are killed and clean, treated water is produced, which will be reused for closed-circuit hunting or for other uses (cleaning, watering, etc.). .). The toilets do not have to be connected to the sanitation network and operate autonomously.
Since WeCo toilets are off grid, they do not consume water. As for the standard connected public toilets, at least 6 litters are used per flush, 10 litters for automatic washing. On a basis of 100 flushing per day, this amounts to using 416,000 liters per year or 416 times what WeCo uses. In addition, with an average 100 users per day, WeCo produces 8,736 litters of treated water per year from collected and recycled urine.

WeCo World Water Day is an event organized by WeCo in Vitry / Seine (France – Paris suburbs) on March 22, 2019 and hosted by Kilowatt, an association that is a “Generator of Festivities”. The Kilowatt Association has transformed this area into a urban, associative and artistic site, that still retains its industrial and energy roots.

Re: World water day March 22: experiment innovative waterless toilets in Paris

Dear Cécile,

Welcome to the forum! Do you have any photos from your event? And what is the role of Caltech? Also, how is this funded (I saw on your website a logo to say that it's supported by EIT, a body of the European Union - en.wikipedia.org/wiki/European_Institute...ation_and_Technology ).

What are your ambitions or time line with regards to commercialising this and making a profit?

I really like how we have been able to follow your progress on this forum since four and a half years now. It all started with a post by Jörg Schaff in this thread in October 2014 (navigate to the first page of this thread to see it)...

Regards,
Elisabeth

Re: French start-up WeCo launches commercialisation of ecological flush toilets with waste-water treatment in a closed circuit

WeCo creates the first eco-friendly, innovative and self-contained flush toilets.
See the video and moe information: www.en.weco-toilet.com/ecological-public...ical-public-toilets/
All excrements are recycled on site into treated water for flushing and watering green areas. We are developing the ecological toilets of the future for cities and together with Alstom a plug & play industrial system ready to be connected to the public toilets of trains and other public places.

Our green technology converts urine into treated water by biological and electrolysis treatments: all bacteria are killed, treated and clean water is produced, which is reused for the water flush closed-circuit or for other uses (cleaning, watering, etc...). The toilets do not have to be connected to the sewer sanitation network and operate autonomously.

WeCo toilets do not consume water since the waste water is infinitely recycled. As for the standard public toilets connected, at least 6 liters are used per flush, 10 liters for automatic washing. On a basis of 100 users per day, this amounts to using 416,000 liters per year or 416 times what WeCo uses. In addition, WeCo does not only save water from flushing, but even produces 8,736 liters of treated water per year from recycled urine.

Since WeCo toilets are non sewered, there is no need to pay for the sewerage and all the costs associated to dig and pipe for the clean and the waste water.

Our customers are: sustainable cities, tourist sites, train manufacturers, construction shelters, modular buildings, event agencies, toilet companies, owners of non-connectable buildings ...

WeCo is always seeking for international cooperation especially in emerging countries to develop humanitarian projects and for scientific expertise in biological treatment to convert the faecal sludge into fertilizer or energy. Any suggestion is welcome”

Re: World water day March 22: experiment innovative waterless toilets in Paris

Dear Ms Cecile,

Hi, my name is Jeronimo Dos Santos, from Timor Leste. Many thanks to share your ecological flush toilets with wastewater treatment in a closed circuit. After doing some research I found that your system is totally removed all organic and inorganic compound (BOD, COD, TSS and bacteria such as Total coliform and E.coli) by Electrolizing it using EC. But, I want to ask several question as I used EC system in treating blackwater and i got difficulty in removing solid parts. questions:
1. Are your system remove solid part by settling down the solids. If so, What SRT and HRT are used in the system.
2. Are your system can remove virus.
3. In this system you used filtration to filtrate effluent from EC and stored treated water in the storage tank and reuse for flushing. How did you overcome the TS and TSS to overcome clogging in your filtration as EC contain high TSS.
4. Are your system (technology) can implement in low income countries.

Thank you,

Thank you,
