Long time ago I didn't follow the discussion on my post, thanks for asking. Please you will find attached the final report regarding to post-treatment of Toilet Liked Biogas effluent. In summary I should say that the results are very good, practical and applicable in the rural area of countries with tropical climate like India. Using sludge treatment wetland not only the quality of effluent is improved in terms of nutrient concentration but also the pathogen reduction is very significant. Additionally, the recovered water can be used for agriculture and harvested plants can be used to feed the animals.
Please have a look the attached report and let me know if you have questions.

Also I will kindly request Elisabeth to post the complete thesis in right location at SUSANA webpage.

Best regards

Manual for greywater treatment in sand and gravel filters in English - by: CWendland http://forum.susana.org/forum/categories/36-constructed-wetlands-soil-filters-and-infiltration-beds/14299-manual-for-greywater-treatment-in-sand-and-gravel-filters-in-english#14299 http://forum.susana.org/forum/categories/36-constructed-wetlands-soil-filters-and-infiltration-beds/14299-manual-for-greywater-treatment-in-sand-and-gravel-filters-in-english#14299
www.wecf.eu/english/publications/2015/ma...eywatertreatment.php

Greywater management is complementing sustainable onsite sanitation solutions such as an ecosan toilet.
This manual explains how greywater can be treated in a sand or gravel filter before being re-used or discharged. Different greywater filter designs have been demonstrated in Georgia in two villages close to the Black Sea by the Georgian NGO RCDA with guidance by the student Lukas Huhn from Hamburg University of Technology. The technology is very efficient, relatively simple, low-cost and can be realized by practitioners in rural and peri-urban areas of most settings.

obituary 1990 by Elisabet Sahtouris, PhD evolution biologist and futurist Gaia’s Dance (Kindle) www.sahtouris.com

~1940-50

~1970

...At eighty-two, Dr. Kaethe Seidel, head of the former Limnology Group of the Max Planck Institute, long nicknamed Bulrush Kate ("Die Binzen Kaethe"), is a tough-minded, clear-thinking scientist with a remarkable record of pioneering work in a kind of biological wastewater treatment that should be far better known and used than is the case. In the course of a professional career spanning over sixty years, she has demonstrated the effectiveness of naturally growing plants in breaking down ballast substances, transposing toxic into non-toxic substances, destroying pathogenic bacteria, viruses and worm eggs, removing heavy metals, cleaning oil spills, removing salt, neutralizing pH, enriching with oxygen, transforming waste water into drinking water and replenishing groundwater --- all with photosynthesis as the sole energy source.

Scientists from NASA, from Japan, from many institutes worldwide who have discovered her [Dr. Käthe SEIDEL] work have visited her to learn more, yet there is relatively little followup given its scope and importance except for the remarkable installations for which she has been more or less directly responsible.

"Why," I asked her, as we sat in the huge old mansion that served as headquarters for the Limnology Group, in the midst of a nature preserve near Krefeld in Germany, where she now lives alone until her immanent eviction, due to sale of the property by the Max Planck Institute.

Her answer was telling. "Men always reach for technology, for development. They insist it will bring us to higher levels of progress. They haven't the patience to work with slow-growing plants, nor do they understand natural cycles as women do. They see my work as farming, not engineering, so they go away and return to their machinery."

"Wait till we run out of water," I countered. "They'll all come running to you then."

"It will be too late then," she said matter-of-factly in her rich, low register voice. "Neither these cabinets, nor the research reports in them, nor I, will be around."

[Sadly, yet perhaps predictably, Dr. Seidel passed away a few months after her eviction.]...
see rest of obituary

Two remarks by Mr. Blumberg (CW-expert):
1. Ingenieurbüro Blumberg:
„Auch die heute übliche intermittierende Beschickung vor allem bei constructed wetlands [PKA] mit vertical subsurface flow [vertikaler Beet-Beschickung] wurde von Dr. Käthe SEIDEL in Form ihrer „Leiterkaskade“ erfunden, eine Versuchsaufstellung, die das Tidensystem (Ebbe und Flut) nachahmt und dadurch den Gasaustausch drastisch befördert. „Das „Auf und Nieder – Einatmen und Ausatmen – Belasten und Entlasten, das war es!“ (Seidel 1974). „In unserem Ebbe-Flut-System wird bei Ablaufen des aufgestauten Wassers Luft mitgerissen und besonders in die Wurzelräume eingezogen, wo sie den abbauenden Bakterien als Energiequelle dient“ (Seidel 1967).“
google-translated: "Also, the now common intermittent feeding especially in constructed wetlands with vertical subsurface flow [vertical bed feed] was developed by Dr. Käthe Seidel in the form of their" invented Head cascade ", an experimental set-up that the Tidensystem (tides) mimics and thereby promoted the exchange of gases dramatically. "The" Up and Down - inhaling and exhaling - loading and unloading, it was "(Seidel 1974)!. "In our ebb and flow system is entrained air at expiration of dammed water and particularly drawn into the root areas, where it serves the degrading bacteria as an energy source" (Seidel 1967). "

2.
Ingenieurbüro Blumberg:
Man lernt u. a. daraus, wie viele Epigonen [m.e. selbsternannte PKA-Guru’s] die fundamentalen Grundkonzepte der eigentlichen ForscherInnen und EntwicklerInnen nur wiederkauen und sich damit wichtig tun, obwohl ihr eigener Beitrag gering oder gleich Null ist.
google-translated: "You can learn, among other things from how many epigones [self-proclaimed CW-guru's] only ruminate the fundamental basic concepts of actual researchers and developers and to do so important, although their own contribution is low or equal to zero. "

For sure you know some more North-Korean or US-inventors of THE CW's from the 1800`s...

I know this excellent paper by Prof. Tanner, but it is just based on "warm" Auckland, NZ condition

My "quick and dirty", maybe educated guessing is based only on "warm & cold" anaerobic experienced made on ABR... I know, not much similar.

During "cold" winter time nutrient uptake by floating plants will be "0", but "The Biofilm" will still do a "job", more or less similar to ordinary aerobic CW's.

Maybe I could use roughly as a start and comparison less needed CW- m2/p.e. for the tropics?

Maybe mentioned reference: Van de Moortel A.M.K., Meers E., De Pauw N., Tack F.M.G. (2010). Effects of vegetation, season and temperature on the removal of pollutants in experimental floating treatment wetlands. Water, Air and Soil Pollution 212:281-297. will indicate more, but I do not have access and it is just based on a laboratory tests. I prefer real rough conditions

Don't know much about FTW specifically, and don't know what leads you to think that 2x would be a good scale factor, but could you compare conventional wetland treatment in cold/tropical climates, and use a similar scale factor?

Dear colleagues,

All textbook on the subject and R&D literature on the Internet on FTW's are based on permanent warm climatic condition.

So, in my educated guessing I would increase tropical HRT guidelines "just" by 2x!?
... risking Eutrofication

I am searching for informal hints based on practical made "cold" experiences.

Thanks in advance.
