Promote VERMIFILTRATION Technology for WASTEWATER PURIFICATION by EARTHWORMS to produce clean water

Dear Members of SuSanA

Thanks for your mail about the Organizing the WORLD WATER WEEK at Stockholm on 24th August. Sorry I won’t be able to participate but I am sending you some IMPORTANT ACTIONS which the Nations have to take to Combat the WATER CRISIS & resolve the SANITATION Problems which is a growing problem all over the world.

DEPLETING WATER RESOURCES on Earth
Less than 1 % Water is Usable by Society – 97.5 % is SALINE in Oceans & 2 % FROZEN in Alps & Mountains. Groundwater is fast DEPLETING all over world. UNEP has warned that within 25 years, half of the world’s population could face hardship in finding enough FRESHWATER for DRINKING, SANITATION & FOOD Production. We use 400 - 600 Liters of FRESH WATER every day for cultural purposes.

About 45 Industrial Chemicals have been found in Surface Water. They are ‘ENDOCRINE DISTRUPTORS’ in very low-parts-per billion. Procurement of Water, Treatment & Supply, and then Treatment of Wastewater after use by Society use huge electricity and emit GHG & Pollutants.

Technology cannot create water, but can only prolong its life by Conservation or Desalinate SEA WATER for Potable Uses or PURIFY WASTEWATER for RE-USE Saving Huge FRESH WATER.


Actions Required by Nations for CLEAN & CONTINUED Supply of FRESH WATER & Help Resolve the SANITATION Problems

a). Promote VERMIFILTRATION Technology for WASTEWATER PURIFICATION by EARTHWORMS to produce CLEAN (Disinfected & Detoxified) WATER for FARM Irrigation & SANITATION saving huge FRESH WATER.

Earthworms body work as a ‘BIOFILTER’. It is highly ECONOMICAL, LOW ENERGY, No CHEMICALS used, NO emission of GHGs, No SLUDGE formed & is ODOR-FREE. It can be DECENTRALISED in Small Habitated Areas.

This system will cover the areas you have indicated in your mail about SANITATION – WASH & NUTRITION; SANITATION in Small Towns; Fecal SLUDGE Management; Wash in SCHOOLS & Combat TROPICAL DISEASES.

(N.B. I worked on this innovative VERMIFILTRATION TECHNOLOGY at Griffith University, Brisbane in 2005-06. It has Several ADAVANTAGES over all Other Sewage Treatment Plants). Over 100 VFT Plants are operating successfully in India. Treated Clean WATER (Disinfected & Detoxified) is used for Garden & FARM Irrigation saving huge Groundwater. One of my Indian VFT Plant is on YOU-TUBE –‘Wastewater Treatment by Earthworms - Rajiv Sinha’.
Several VFT Plants are also successfully operating in Chile, Mexico & Venezuela by the works done by Prof. Maria Soto of Univ. of Chile (This email address is being protected from spambots. You need JavaScript enabled to view it.). We did not know each other until my paper was published in the UK Journal The Environmentalist (2008; Vol. 28: 409 – 420). She wrote to me & congratulated after seeing my PAPER. Her works were PATENTED by the University & not PUBLISHED.

Believe in Sir Charles Darwin who called Earthworms as ‘Unheralded Soldiers of Mankind & Friends of Farmers’. I am attaching 6 page INFO on VFT for some details of the Technology.

b). Promote DESALINATION Technology to Remove SALT from SEA WATER & USE them as FRESHWATER. With fast DEPLETING GROUNDWATER it is the only hope for Civilization to SURVIVE in future.
ISRAEL has large SOLAR STILLS& evaporates about 120 million tones of SALINE WATER to obtain FRESH WATER (also POTASH for Farms). SAUDI ARABIA makes highest production of FRESHWATER from SEAWATER by Desalination.

c). Promote GROUNDWATER RE-CHARGE Technology to use the RAINWATER & Waters from RIVERS & CANALS to re-charge the Groundwater by pumping them UNDER-GROUND.

Re: Promote VERMIFILTRATION Technology for WASTEWATER PURIFICATION by EARTHWORMS to produce clean water

Dear Prof. Sinha,

Thank you for your posting whereby I am specifically interested in vermiculture (filtration and composting) as you also know through your correspondence with Elisabeth in which I have been copied.

Referring to your posting, to your YouTube video and to some of your papers, I have the following questions especially regarding sewage (not sludge) treatment:
1. Your research work at Griffith University seems only had an impact in India where you say 100 VFT plants are operating. I am impressed by the versatility of the worms in dealing with all sorts of waste. Why has this not been recognised in other parts of the world at larger scale since it seems to be a simple, economic and ecological technology? The revolution quoted in your 2009 paper hasn’t taken off yet.
2. Is it possible to receive technical details (m3 treated, m2 bio-filter required, m3 humus produced, bio-chemical properties of effluent, etc.) for the commercial VFT plants (maybe from TransChem)?
3. How is the humus from the bio-filter in your video harvested?
4. Is there evidence that the worms by disinfecting and detoxifying the sewage (or sludge) do not become hazardous waste themselves? Otherwise, how do I separate humus from dead worms?
5. I am not sure about my next question: your video says that nutrient rich effluent is produced and used for irrigation. At the same time, it is claimed that BOD/COD is reduced considerably. Is a low BOD/COD not an indication of low nutrient content?

Looking forward to your response and advice,
Kind regards
Hajo

Re: Re. Mail of Mr. Hajo Schaefer about my VERMIFILTRATION Tech. for Wastewater Treatment for REUSE of Clean Water: Prof. Rajiv Sinha, Australia

Dear Members of SuSanA FORUM,

Mr. Hajo Schaefer wrote to me expressing interest in my VRMIFILTER TECHNOLOGY for WASTEWATER Treatment by EARTHWORMS & REUSE of Clean NUTRITIVE WATER in Farm Irrigation. Infact Late Prof. Jose Toha & Prof. Maria Soto of Univ. of Chile (This email address is being protected from spambots. You need JavaScript enabled to view it.) were pioneer workers on Wastewater Treatments by Earthworms. Their works were PATENTED by the University & hence not PUBLISHED. We did not know each other until my PAPER was published in the UK Journal The Environmentalist (2008; Vol. 28). She wrote to me & congratulated after seeing my PAPER. Several VFT Plants are also successfully operating in Chile, Mexico & Venezuela by the works done by them. You can write to Prof. Soto to know more about me.

Answers to some of his Questions

1). Why my VF Technology has not been recognised in other parts of the world ?

I am regularly invited for LECTURES in Indian Universities & in Conferences every year. An Indian Company TRANSCHEM Agritech who were working on WASTEWATER Management became interested in my Technology & I provided them the SCIENTIC DETAILS FREELY in the interest of ENVIRONMENT & SOCIETY. They COMMERCIALISED my Technology with some SCIENTIFIC IMPROVEMENTS & REWARDED me after installation of some VFT Plants in India.
It was hard to convince my Australian Wastewater Management authorities. Recently I have received some mails from City Councils.

I came in Contact with US Farmer Er. George Hahn in a ‘Farmers Conference’ in 2014. He also became interested & installed VERMIFILTER Plant in his Farm to Treat his DOMESTIC & CATTLE FARM WASTEWATERS for REUSE in Farm Irrigation. I also educated some FARMERS in China & The Netherlands during Conferences. They are working on it but have NOT UPDATED me.

2). Evidence that the Worms by Disinfecting & Detoxifying the Sewage (or Sludge) do not become HAZARDOUS WASTE themselves?

DISINFECTION: Harmful Microbes (PATHOGENS) are killed selectively by the EARTHWORMS through PHYSIOLOGICAL, MICROBIAL & ENZYMATIC Actions. They release COELOMIC FLUIDS that have ANTI-BACTERIAL properties and destroy all PATHOGENS in the SEWAGE & SLUDGE or any WASTE BIOMASS. Earthworms can distinguish between HARMFUL & USEFUL MICROBES in the WASTE Materials & SOIL & selectively DEVOUR on the HARMFUL PROTOZOA, BACTERIA & FUNGUS as food leaving the USEFUL ones.

In the intestine of Earthworms some BACTERIA & FUNGUS (Pencillium & Aspergillus) have also been found. They produce ‘ANTIBIOTICS’ & kills the PATHOGENS in the SEWAGE & SLUDGE making it virtually STERILE.

DETOXIFICATION: Earthworms can tolerate TOXIC CHEMICALS in the Environment. After the Seveso Chemical Disaster in 1976 in Italy, when a vast area was contaminated with extremely toxic chemical like TCDD (2,3,7,8-tetrachlorodibenzo-p-dioxin) several fauna perished except for some species of the Earthworms (E. fetida) that survived.

Earthworms ‘BIO-ACCUMULATE any TOXIC CHEMICALS including ‘Heavy Metals’ present in the SLUDGE & BIODEGRADE or BIO-TRANSFORM’ them by ENZYMATIC Actions & render them HARMLESS. They also change their IONIC STATE so that they become NON-BIO-AVAILABLE for plant roots. Metals are bound by a special PROTEIN called ‘METALLOTHIONEINS’ in Earthworms which render them BIOLOGICALLY INACTIVE.

Each Earthworm ‘eat the WASTE Materials’ at least 8 times & leaves the END PRODUCT free of all CHEMICALS. However, there are chances that some Heavy Metals may still remain in the VERMICOMPOST if the Worms are not properly segregated out or they DIE & DISINTEGRATE. There has to be large number of Earthworms eating the Sewage SLUDGE and they all have to be segregated out before the use of VERMICOMPOST.

(N.B.I am attaching details on DETOXIFICATION & DISINFECTION by Earthworms).

3). How is the HUMUS (It is DEGRADED SLUDGE as VERMICOMPOST rich in HUMUS) from the BIO-FILTER BED (shown in my VEDIOFILM) is harvested?

Earthworms regularly EAT the SOLIDS in the SEWAGE & excrete them as their VERMICAST which collects as UPPER Layers in the VERMI-FILTER BED. They have to be Periodically Scrapped manually after they become THICK, leaving intact some LAYERS below in which resides good population of EARTHWORMS whose BODY work as BIOFILTER.

4). Is Low BOD / COD not an indication of LOW NUTRIENT content?

Levels of BOD & COD in SEWAGE has nothing to do with NUTRIENTS. It is the TDS (Total Dissolved SOLIDS) which provides some essential NUTRIENTS like NITRATES & SULPHATES which is removed only by 16 %.

The useful bio-available NITROGEN as NITRATES (NO3) in Sewage are increased from 10-20 ppm to over 50 ppm, the PHOSPHATES (P2O5) from 1-2 ppm to 5-7 ppm & the POTASSIUM (K) from 10-15 ppm to 20-25 ppm in the VERMIFILTERED water which becomes highly NUTRITIVE (rich in NKP) to be used in Agriculture with considerable savings on FERTILIZERS & WATER for Farm Irrigation.

5). Technical details for the Commercial VFT Plants

Yes you can contact the CEO Mr. Atul Shroff (This email address is being protected from spambots. You need JavaScript enabled to view it.) & Technical Manager Dr. Mandar Prabhune (This email address is being protected from spambots. You need JavaScript enabled to view it.) of Transpek in India. They will be happy to INSTALL a small VERMIFILTER PLANT in your locality as a PILOT Plant to convince you all about its huge ECONOMIC & ENVIRONMENTAL ADVANTAGES over all other STPs. They will provide you the list of the MATERIALS to be used & their SERVICE Charges.

Also read my BOOK on ‘Vermiculture Revolution : The Technological Revival of
Charles Darwin’s Unheralded Soldiers of Mankind’; published by NOVA Science Publishers USA in 2011. ISBN 978-1-61122-035-3; You can write to NOVA & ask for my BOOK.

Re: Re. Mail of Mr. Hajo Schaefer about my VERMIFILTRATION Tech. for Wastewater Treatment for REUSE of Clean Water: Prof. Rajiv Sinha, Australia

Dear Prof. Sinha,

Thank you for your quick and elaborate response.

I guess VFT plants are not used more often because they are not (yet) state of the art. And maybe they are too cheap in construction and O&M to be considered as competent technology. But that are just my guesses. And I hope I will receive more detailed technical information from TRANSCHEM, who have not yet responded to my email.

To answer my question whether worms become hazardous waste by processing heavy metals, you use a lot of ‘BIO’ : worms bio-accumulate chemicals, bio-degrade or bio-transform them and render them biologically inactive. Nevertheless, you say that the worms need to be segregated before the use of the vermicompost. My conclusion: the worms become hazardous waste and need to be treated separately. Any comments from someone else who has knowledge of this?

Scrapping the top layer to harvest the vermicast seems to me a laborious job since this layer still contains a lot of worms which require separation (see previous topic). It cannot be seen in your video but I suspect that a more appropriate method would be to have distinct areas in a vermifilter which are fed with sewage alternatively allowing the worms to migrate from ‘dry’ (no food) to ‘wet’ (plenty of food) areas whereby the vermicast can be harvested containing less to little worms.

Following your response on BOD/COD vs. nutrient content, I read a bit more on the internet and found the following: nutrients (nitrates and phosphates) cause growth of plants and algae. These are decomposed by microorganisms using oxygen, the required quantity of which is measured as BOD. Standard WWTP therefore try to reduce nutrients (and organic waste) from effluent released to rivers and lakes. Vermiculture reduces organic waste from sewage but also increases nutrients levels of effluents from vermifilters and therefore should not be released to rivers but rather be used for irrigation giving the nutrients back to the plants. Which will require building VFT plants not at rivers but rather above fields.

Thanks for the contacts from TRANSPEK in India. I will contact and face them with our plans and requirements in Rwanda (not Germany!).

Looking forward getting some more comments from others regarding the use of vermiculture at a community-/institutional level. If there has been a discussion on this before, please refer me there!

Thanks and ciao
Hajo
