Very interesting - and as a non-techie, Thammaratt's system does seem to be very similar, although maybe the thermophilic septic processing part is different?

Can you explain the volumes that can be processed - I see mention of 800 students and 4 units, so can obviously cope with 200 students per day, but what is the volume limit per unit per day?

On the cost side - it's EURO1,500 / USD$1,800 per toilet?

This for the cheapest system and goes up from there? www.aquatron.se/products/price-list/t

After 10,000 toilets and refinements and economies of scale, does it still need to be so expensive?

I know there are countless hours of r & d and cleverness and lots of money gone into it (and of course, the profits needed for more r & d etc and to reward you guys - and I am all for a profit - the more the merrier:), but it doesn't seem that there are any particularly expensive components that justify such a high commercial price?

Perhaps country pricing differentials are at play, but I am sure there would be manufacturing and distribution partners in Asia and Africa who, under your licence, can build and distribute systems cheaper, sell more and ensure that many more people get the benefit of your ideas and technology

Perhaps something to consider?]]>

Thanks so much for sharing your project here. Can you tell me some more about your process of increasing settling using ultrasound? We are also trying to settle solids rapidly in our Nano Membrane Toilet so surely have a lot to learn from you!

Many thanks

As Ben and Marjin already mentioned, it would be great if you could share some more details about the toilet you developed. Did you design it with an Irish context in mind (where about 30% of the population is served by on-site systems) or with a potential for application in middle- and low-income countries?

There is quite some research being done on on-site wastewater treatment, both globally and in Ireland, here at Trinity College in Dublin; have you had the chance to present your prototypes to a wider audience here in Ireland so far?

As Ben says above, we are all very curious to see what you have come up with.

With regard to your question. It will be very hard to suggest a place to test your toilet without knowing what you designed it for. I mean that to evaluate your design you have to find a location that presents the situation it was designed for.

If you just want to take on a very large challenge, consider looking at sanitation for informal settlements. Or retro-fitting into densely populated old areas of cities which have grown massively. I would also suggest doing your research in a country where there are such areas, but that at the same time have good universities and research facilities. I think some East African countries or Bangladesh / India may be good candidates.

Finally, usually it is things like user engagement, institutional set-up and a larger enabling environment that determine success or failure and less the actual technology

To your question : which site globally would be the most effective / productive proving venue ?

I invite you to first prove your concept within the best ecosan expert team you ever dreamt of : The susana FORUM !

Looking forward to have some info on your profile, and for you invention photos, website, technical drawings, etc ...

Additional prototype development is being funded by the Irish state with a few to future manufacturing here in Ireland .

The co modern is capable mass installation / usage post disaster zones , rural and low to medium density population centres . My query is simply which site globally would be the most effective / productive proving venue ?

Thanks for these explanations. Very interesting.
Could you also post some photos of these installations in Swedish schools? How many Swedish schools have these toilets and what is their motivation (are they perhaps in remote rural areas and not connected to a sewer system?)?

Are the school caretakers (janitors) or maintenance staff OK with dealing with the compost? That's very progressive! I don't know if German care takers could be convinced.

Do you have any photos of the maintenance tasks? Are there any requirements by the Swedish legislator to prove that the compost is safe enough to use in school gardens? Then again, only a few litres of compost per year from an entire school is not a lot.

And I think you missed this question of mine: Is the hydrocyclone separator patented by your company? (i.e. would someone like AIT not be allowed to also apply this design, too?)

Regards,
Elisabeth

P.S. I have alerted Thammarat to this thread by e-mail.
P.P.S. It might be a good idea to split off the last few posts and put them in a new thread?]]>

One of our retailers gave me this link to your forum.

The Aquatron separator was invented in Sweden by an engineer at IBM during the 80s, the first working systems were manufactured and installed in the beginning of the 90s.
In the end of the 90s there was a lot of big systems installed in public schools. The biggest one had 4 Aquatron systems that served 800 students, this system was up and running for over 15 years. With the Aquatron system the architect installed urine diverting toilets, the urine was collected in big tanks and local farmers used this for irrigation. Unfortunately, later on, more very young students (4-5 years old) was added to the school and the usage of the urine diverting toilets was too difficult to them. The direction of the school disconnected the toilets and the Aquatrons with them (even though they never had problems with the Aquatron systems)...
Today our best reference in Sweden is a school in Lund where 200 students use one Aquatron system since 1997.

Aquatron has changed owner and manufacturer during the years, and we estimate that over 10 000 systems been manufactured over the years (there is no record).

Our main sales is in Scandinavia, but we have clients all over Europe, Belize, USA, New Zealand, Australia and India. Of course we have some private persons that ordered systems and we don't know where in the world it's installed.

The cost on the Aquatron systems depends on the demands, but the prices estimated in Euros is from 1500€ and up included the composting chamber.

The maintenance cost is very low since most of our clients serve their own systems and the only part that needs to be maintained or served is the wire ring in the separator.
The schools only empty a few liter per year of compost.]]>

They have quite a good description as well

Interesting solution. Seems to be the second time that a solution of reinvent the toilet is "reinvented". I don´t know if it is a copy or just "2 thinkers, one thought" as many times with good products.

Here is the picture of the product.
