Merry Christmas and Happy New Year

Hi to all, with my post n. 100... I wish you a Merry Christmas and a big Happy New Year full of happyness and love!!!

wastewater treatment with algae...

I love the algae world and a lot of things can be done with these spectacular mico-organisms. Pharmaceutical, proteins, cosmetic... and also wastewater treatment.. yes, algae live with nitrogen and phosphorus that are common pollutants.

Copied from the http://www.oilgae.com web site I can summarize the following text:
" Algae are an important bioremediation agent, and are already being used by many wastewater facilities. The role that algae can play in wastewater remediation is however much higher than its current role.
Use of algae as the bioremediation agent enables us to solve two key problems: increased use of chemicals and high energy costs. Thus, algae-based waste water treatment is a powerful avenue for sustainable wastewater treatment.
Algae-based remediation of wastewater is not without its challenges; however, the potential is so high and the problem so critical that there are a number of research efforts - both in the academia and in the commercial sector - ongoing in order to address these challenges."
A good report can be dwnld or buyed in the oilae.com web site..

Another good reading with a literature review is here...tidskriftenvatten.se  as pdf document named "WasteWater treatment With microalgae – a literature review" written by Karin Larsdotter (School of Biotechnology,  Stockholm)

Green Water ... a company in Africa

I met this company on facebook by a link of a dear friend Rob Crook.
By facebook I copy this information: "GreenWater is an environmental consultancy firm based in Mombasa, specialising in wastewater treatment, environmental advisory services, waste management and first aid training. The Company founder and director is Sarah den Haring (http://www.green-water.org)".

Here below few photos taken from their web site n fb (for more information and for the captions see their page on facebook (http://www.facebook.com/pages/GreenWater/193329114107387) .

... while I speak some lectures...

here below a beautiful image of my presentation in Turkey last May...

and here few photos of my presentation at the important conference about swine wastewater treatment with treatment wetlands held in Italy and organized by www.artecambiente.it. I have made two post about this project. ( fitosuini )

Tree House with treatment wetland!!!

Oh Yes, here in Italy we have a lot of problems... but also good ideas. Take a look at this good realization in north of Italy at the Azienda Agricola OASI di Davide Carlini a Certosa di Pavia (PV) where ArtecAmbiente built this special treatment wetland. This is a rural house (Agriturismo in Italian language) where you can spend your holidays and free time in the countryside... and also taste the good hand made beer produced by the howner (http://www.birrificiorurale.it).

World Toilet Day - 19 November

Today is World Toilet Day which is closely tied to Millenium Development Goals number 7 that aims to halve, by 2015, the proportion of the population without sustainable access to safe drinking water and basic sanitation.

Around the world, 1.1 billion people defecate in the open, contaminating their environments and water sources and spreading diseases like diarrhoea, which kills 2,000 children under 5 every day. 

I think is the time to do something. 

Me and an italian colleague (Mauro Lajo of www,fitodepurazione.blogspot.com) are working to do that. We are developing two project to promote the safe sanitation and spreading the use of toilets. Contact us if you want be part of the team.

Let' go to build a treatment wetlands, let' go to build a reedbed, let's go to build a constructed wetlands... let's go to do somethings!

video of the Treatment wetlands outflow !!!

Hi, this video is made by the Company head of ArtecAmbiente srl (Mauro Lajo) in one of their treatment plant here in Italy!

Have you never seen what kind of water came out from a treatment wetlands?? this is one of the main reasons for building TWs!!! enjoy it!!!

As Mauro say in the video... "you cannot hear, it doesn't smell!!!"

treatment wetlands and winery wastewater

Hi, here my last project design and realization by ArtecAmbiente (www.artecambiente.it). A treatment wetland for the treatment of winery wastewaters. This was made last week in Puglia, a region in the South of Italy where the red wines are sooooo gooooooooood.
This kind of "pollution" is really particular: high cod, high bod5, low pH, high volume in short time,...
TWs is the right choice also in this situation!!
Here below some photos of the realization!  .... next week they start the harvester of the grapes and the TW is ready to get the process waters!!! Yeahhh!! NO MORE POLLUTION!!!

Sustainable Sanitation and treatment wetlands

Treatment wetlands are a key tool for the sustainable sanitation all over the world. Here below I post a link to a good handbook namend " Treatment Wetlands – Sustainable Sanitation Practice " by the ECO SAN club published in July 2012.

Download the full document here:
http://www.ecosan.at/ssp/issue-12-treatment-wetlands/SSP-12_Jul2012.pdf

The document is posted in the following pages:
http://sanitationupdates.wordpress.com/2012/08/01/treatment-wetlands-sustainable-sanitation-practice-july-2012/

And take a look to the home page at http://sanitationupdates.wordpress.com/ because there are a lot of useful information.

THE FLOATING TREATMENT WETLANDS

The Floating treatment System allow the wastewater treatment at water level. The wastewaters are usually treated away from the points of origin. The “on water treatment” needs specific floating elements that are vegetated with different species able to extend their roots systems in the water column.
The action of the roots is double: physical filtering of the waters and nutrients uptake. This system is easy to install and to manage during the time.
Usually the floating wetlands can tolerate high water level fluctuations typical of rivers, lakes, canals, etc.
Floating wetlands have also a beautiful aesthetic aspect!

The examples worldwide give a lot of differents ways for realize a floating wetlands. Here below few examples.

ILVA TARANTO

As you know in Taranto in the South of Italy there is one of the biggest european steel-metal factory (ILVA - Taranto). After many years of strange-trouble management of metal production the italian judgement system start a process to close the factory because during the years they had caused a lot of environmental pollution and human health deseases....
Now United Europe and the board of Ilva will start to finance the improvement  of the production in order to realize a green steel factory !!! 

Also treatment wetland could be used to ameliorate these kind of factory: roofs and floors runoff waters... etc could be trapped and treated! and finally you can obtain treated waters that could be reused in the steel production!

if you are an investor and have in mind that treatment wetland could be the right solution  to do that contact me !

natural wetlands

I'm here in Austria and I found a lot of natural wetlands at 1900, 2300, and more meters above sea level  .... sometime I forget that everything start from these! As stated by the RAMSAR CONVENTION (www.ramsar.org) wetlands are areas of marsh, fen, peatland or water, whether natural or artificial, permanent or temporary, with water that is static or flowing, fresh, brackish or salt, including areas of marine water the depth of which at low tide does not exceed six metres ... in particular are also a natural humid environment where water, plants and soil stay together, live together, change and evolve depending on climate, hydology, human impact (see my mountain bike's rear  wheel) etc... enjoy the images below with juncus (the green), eryophorum (the white plume), orchys (the violet), and the carnivorous pinguicola (the pale green) found here in Austria in the area of Fiss:

Join it!!!!

news from my holidays.....develop an innovative treatment wetlands!!!

hi, I have received an important request from an international company to develop an innovative system in the field of the treatment wetland applications.

Please if you are a POSSIBLE INVESTOR  contact me I'll put you in contact with this company!

back soon!!!

hi, I'll be back as soon as possible with a lot of news and ideas about treatment wetlands world!!!

Wetland conference In Italy

the vice-president of the Ticino Park have said: "treatment wetland is the future".

43000 m3/d in 240Ha ... is this a treatment wetlands?

YES, is a treatment wetlands... wow!!! fantastic!!! 43000 cubic meter a day in 240 hectares.. is this the biggest treatment wetlands in the world?  As wrote in the article "REPORT FROM THE MIDDLE EAST REGION: LARGE-SCALE TREATMENT OF OILFIELD PRODUCED WATER USING WETLANDS IN OMAN" by Dr. Tom Headley and Dr. Roman Breuer published in IWA Specialist Group on Use of Macrophytes in Water Pollution Control: Newsletter No. 39, various full and pilot-scale treatment wetland projects have been realised in recent years for treatment of sewage and sludges in Oman, Qatar, the UAE and Jordan. Wetlands are also playing an important role in treating industrial wastewaters on a large scale, such as the 600 ha wetland+pond system  that was designed and built for treating residual water from an oil field in Oman.
They recover oil, they save energy for water treatment with traditional systems, they create new environment in arid climate zone, they save below ground aquifer...

They also win the "2011 water global awards"

the vetiver network....a fantastic web site

The vetiver network is a really fantastic web environment.. you can find and ask everything you're searching about this plant species and his application for water treatment.

This is the link for Vetiver Systems for Waste Water Improvement and Other Related Water Quality Issues : http://www.vetiver.org/discus/messages/16/16.html and there are at least 30 discussion links related to vetiver and water purification such us for example.
- Effluent pond treatment using vetiver grass:  http://www.vetiver.org/discus/messages/16/778.html?1255777325
- Basic household system: http://www.vetiver.org/discus/messages/16/1057.html?1211996863
-Vetiver for Sewage treatment in Australi:a http://www.vetiver.org/discus/messages/16/492.html?1141668160

... and many others!!!


thanks vetiver!!!

a thought arise from an article of National Geographic:

In the last NG magazine of June there is an interesting article about solar storms written by Timothy Ferris:

Sun Struck - The space-weather forecast for the next few years: solar storms, with a chance of catastrophic blackouts on Earth. Are we prepared?

http://ngm.nationalgeographic.com/2012/06/solar-storms/nasa-photography

<A Carrington-class storm could fry more transformers than the power companies keep stockpiled, leaving millions without light, potable water, sewage treatment, heating, air-conditioning, fuel, telephone service, or perishable food and medications during the months it would take to manufacture and install new transformers. A recent National Academy of Sciences report estimates that such a storm could wreak the economic disruption of 20 Katrina-class hurricanes, costing one to two trillion dollars in the first year alone and taking a decade to recover from.

“We cannot predict what the sun will do more than a few days ahead of time,” laments Karel Schrijver of Lockheed Martin’s Solar and Astrophysics Laboratory in Palo Alto, California. 
(full text and video at http://ngm.nationalgeographic.com/2012/06/solar-storms/ferris-text).>>


In the underliner text you can read that everything that works with energy input may have problems.. also traditional sewage treatment!!!
Well, usually treatment wetlands do not have problems because the energy input is very limited!!! an horizontal flow bed doesn't require energy or pumps for his functioning... a vertical bed could be feeded with a mechanical syphoon!!!

cold climate treatment wetlands.... need info for Finland development

Hello Wetlanders..... would you help someone in his research on wetland systems? This is a message from Finland, my friend is searching info about treatment wetlands in cold climates. Below his message, could you help him on his search? Thanks a lot in advance! 

Contact him directly at: gbor.hrvth@gmail.com

Hello!

I would like to thank the opportunity to Davide Tocchetto for offering the possibility to post a brief inquiry on his blog.

I write my thesis about horizontal subsurface and surface flow constructed treatment wetlands feasibility in Finland. I concentrate my research finding similar methods and conditions (cold, boreal climates) around the world so I would have a great access of variety works which I could use in my thesis as literature reference methods which would prove the successful feasibility of such methods in cold climate.

I am looking for studies, projects which I could read and hopefully would help my work. I am mostly interested in methods which were carried out under cold climate.

Thank you very much!

Hi, are you searching something about Treatment wetland systems? Look here which are the best results up to date you can get on Google search:

TWs in cold climate - JAPAN case!

My dear friend Kunihiko Kato working at  National Agricultural Research Center for Hokkaido Region, National Agriculture and Food Research Organization(NARO http://www.naro.affrc.go.jp/en/about/organization.html)   is also a TWs  designer. Its specialization is project and building of TWs for cold climates zone for high strenght wastewaters like dairy milking parlour and pig wastewaters and potato starch processing wastewaters. These are thypical activities in Hokkaido-Japan. 


In November 2005 was constructed the first  real-scale hybrid wetland system to purify milking parlor wastewater. The main character of the system was the combination of aerobic and anaerobic beds (vertical +  horizontal), a self-priming siphon for intermittent flow into the vertical beds, first volcanic gravel bed to decrease SS and a larch wood chip layer to prevent from icing in the cold climate. 


The first year of functioning was summarized in a useful paper published in the WETPOL conference proceedings held in the beautiful city of Gent (Belgium) in 2007: "First year’s performance of real-scale hybrid wetland system for the treatment of dairy wastewater in cold climate in Japan  K. Kato, T. Koba, H. Ietsugu, T. Saigusa, S. Yanagiya, T. Inoue, K. Kitagawa and S. Kobayashi ."
From this article I copy here the conclusion:


"We could use hybrid wetland system all year round to purify milking parlour wastewater in cold climate in Japan from the first year if the loading rate was appropriate."
In my opinion this is a great target after just one working season!


Many other publications were made from 2005 and a lot of information rise from Kato research activities! Well done Kunihiko I hope to visit your plant in the next future!


here some photos!
