First SAFF project in Denmark to treat PFAS contaminated water at ”Ground Zero”, Korsör Fire Fighting school


Congratulations Denmark! You have just received  your first SAFF – Surface Active Foam Fractionation unit. And we can’t wait to show all who is interested the capabilities as well as sustainable, effective and economic PFAS water treatment technology by EPOC Enviro  – and results as they come in.

The commissioning of the SAFF is a part of the Horizon2020 SCENARIOS Project EU. A project where EU has granted 3 teams to evaluate ”all” in regards of PFAS entering routes to the environment, routes of transport in the environment, toxicity, effect on human and environmental health and much more, as well as evaluation of sustainable and economic remediation and destruction methods. In short, the project is described as EUs take on being best in the world at PFAS.
And Envytech Solutions AB is an important part of the project, both supplying the SAFF technology as well as managing the role as team leader for Work packages 7 – Remediation.

The treatment uses no consumables such as filter medias or chemicals, and remove up to 99,9% of PFAS6 compounds, as well as some shorter chain compounds. However, as research by incredible biotech company and Envytech partner Allonnia, show potential of additives to further enhance the removal efficiency of short chain PFAS in the SAFF, we will be adding different amendments and research their potential to increase SAFF removal efficiency.

The unit on site is a SAFF20 unit with treatment capacity of 7-12 m3/h, depending on the water. SAFF20 has the capacity to perform 2 concentration steps (up to 500 000 times), producing minimal waste, only using 0,7 kwh/m3 treated water. A difference to the SAFF40 system, being able to achieve concentration factors of up to 2,5 M times.

The unit will stay on site until July 2024. Visits to the plant, as well as information seminars will be organised throughout the whole treatment period, as soon as the plant is tuned in and results arrive.

So if interested in our system, solutions and the Horizon project. Keep following us on LinkedIn, and contact us for information and for interest in seeing the unit. It will be worth the time, and as we all now, ALL becomes better with bubbles 😇🫧

Another load of RemBind loaded for remediation of airport soil


If you have followed the Envytech Solutions AB PFAS crew, and our presentations of soil stabilisation, you will be aware of the huge leachability that even light to moderate soil have on the underlying groundwater.

In the presentations showing our leachability work, one can see that for example, 48 µg/kg PFAS (43 µg/kg PFOS) , in a soil that has been sitting out in the environment for years and years, living the everyday challenges of life, leaching as can be expected, still leach 11 000 ng/l when trialed in a 2 step leachability test. In Sweden, we have a guideline value for PFAS4 (PFOS, PFOA, PFHxS, PFNA) of 4 ng/l. So easy to see, that even this kind of low contaminated soil, is causing major contamination of the groundwater, that the site owner.- as well as the society and environment – will have to pay for.

Stabilisation is YES keeping the contaminant on site and is still the liability of the site owner. But the risk factor is majorly decreased, and further spreading of the contamination is immediately stopped, as well the increasing cost for ground water treatment. Something that should be taken into the equation.

Why Rembind by Envytech . Well compared to many other carbon products we have trialed in the field, full scale, Rembind is easy to apply, an economic solution when compared to other carbon, and a product that through all our full scale projects, are proving to minimize leachability with up to 99,9% , or whatever the site owner thinks is a reasonable number. This as it all comes down to amount of Rembind (%) used. And as you can see in the table below, we achieve immense reductions with very limited percentage of additive.

Something that does seem to be forgotten in lab studies and other work performed in laboratories, where the clients economics, or the ability to get a good ful scale performance, is never valued.

As I tend to say. Food for thought.

Summary of Life-Source project review meeting on first PFAS remediation in Spain as well as plans for Swedish site


Massive day yesterday with information bonanza for over 9 hours. A head spin yes, but to much science and tech is just awesome 😎.

We talked about the awareness of PFAS at local EPAs in Spain, and how that is changing with increasing knowledge about PFAS. And off course also due the fact that Spain has now a PFAS legislation, much thanks to, this project, amongst other.
– Now how cool is that 👌👏. Talk about making change for real.

We went through the very successful regeneration procedure for AEX Ionexchange resin that Leonidas Perez-Estrada at EURECAT is in charge of, offering this possibility to all users of the Purolite, An Ecolab Company PFAS resins

And last and but not least, we did some professional filming for the video that the project is producing to further increase the sharing of the knowledge and data obtained throughout EU and the world. Hollywood next 🎥

Day 2 coming up, so stay tuned for more updates and data!

Incredible day kicking off another large PFAS stabilization project using Rembind


Wonder how stabilization of PFAS contaminated soil can be done? For this 4000 ton stabilization project for PFAS contaminated soil from an airport, our client offered interested clients and problem owners a live show. I have seen all our projects performed, but this time was the first using an Allu bucket to mix Rembind – a patented well documented and tested stabilization product from RemBind  Australia, with the contaminated soil. We are used to working with tumble screens or vibrating screens, but as our client Dåva Landfill are used to mix with an Allu bucket, we were super keen to see the result.

And as you can see, it works very well.
The Rembind was premixed to a 10% mix, and this soil was then spread on top of approx.100 tons of the contaminated soil with a front loader. The soil were then mixed with the Allu bucket to a 1,5% Rembind concentration. You see one mixing round in the film, and another 3 were to be performed.

Lab scale results show that 1,5% Rembind minimize leachability of all PFAS28 with minimum 95%. The soil will then be landfilled in sealed cells, to provide a long term minimal leachability setting. And Job Done  ✅👌

We might not get greeted by Nasdaq, but we are close to present a similar sustainable solution for destroying PFAS – In Europe 🇪🇺💪👊


It feels like yesterday, but it’s 4 years ago, I first met the OPEC Systems – protecting and improving our environment – team and saw the potential of SAFF. Two years later we launched the first full scale mobile SAFF system here in Sweden, treating complex leachate for the first time in the world, using Foam Fractionation.

It has since then been a mind-blowing journey of hard work, passion, sweat and tears – because it didn’t start off being just bubbles in water, even if it sounds that way. It’s an experience heavy, learn by doing and optimizing treatment tech journey, and we have come really far.

My goal has since the start been the a sustainable zero waste solution. And yes it stings that we didn’t get to be the first, but it feels ok as the US is a tad bigger and lately a lot more advanced. So congratulations to EPOC Enviro team and Kent Sorenson with team Allonnia for amazing work.

But Europe is still up for grabs, and we are going at it full throttle, teaming up with some super potent partners for destruction, and with our first test projects already on the go.

So wish us luck, and keep following our journey for a sustainable concentration and destruction of PFAS solution. We will be out there  with a hand made sign when we make it, if no one makes one for us 😎 🤞📣

Envytech and team SCENARIOS Project EU H2020 collects insects, biota, soil and groundwater to trace PFAS transport


Beautiful days, beautiful team, beautiful work. And beautiful photos! 👌📸.

The quest to map the PFAS journey into the environment through air, water and soil, into plants, insects and animals, and into its last  almost permanent housing, the human body continues. And as a part of the work, we last week teamed up at a heavily contaminated site in Sweden to sample as many receptor ”medias” as possible, to try and map quantity and routes for PFAS.

In these nature rich photos our project manager Say Svanström shines with energy  as a result of being part of this important work. And who wouldn’t. The fate and transport of PFAS is one of the world’s most rapid growing worries, and we need all efforts possible, to help prove the consequences of this, in order to get a ban for these toxins.

Envytech is a partner in team Scenarios, lead by our incredible team leader Francesco Dondero, PhD.  We are assigned Work Package leaders for WP7 – Remediation – and 18 months into the project, we are getting ready to move from Bench scale to full scale remediation of PFAS contaminated groundwater at Korsör in Denmark.

For more info on us, the project or our technologies, please contact Helena Hinrichsen or Say Svanström.

Envytechs first generation 2 SAFF40 has arrived.


Join the team as they open up the doors to inspect the latest upgrades that we have been a big part of developing. This unit will soon treat complex leachate for the two years that are left on our contract at Telge Återvinning in Tveta, Södertälje, and can be viewed from mid April 2023.

So if interested, contact Helena Hinrichsen

New month, New country, New SAFF project – and new area of use:  Water Treatment for PFAS Soil Washing water


We are immensely proud and excited that together with one of the most environmentally beautifully companies we have met, have started this trial and world first combination of PFAS Soil Washing and Surface Active Foam Fractionation (SAFF) treatment from EPOC Enviro OPEC Systems, of soil wash water. And first ever SAFF project in Belgium 🇧🇪👌👏

Water for soil washing is used during the day and treated by SAFF, and all other wash steps during the night, allowing reuse and elimination of the need of activated carbon, minimizing PFAS waste and carbon footprint.

As different soils produce different waters, we are developing a settings guide for different soils, TOC content and PFAS concentrations and signatures This in order to minimize the need of control samples, and to maximize the possibility of foam watching – as getting that just right foam tells the same story as a verification lab analysis.

We are heading into this project in search of a beneficial partnership in Belgium, and so far the experienced, curious and professional staff are exceeding every expectation. So hello Belgium 👋. Great to be here, and we are hoping that this is the first project of many.

New month, New SAFF project. Let us present treatment of PFAS contaminated canal water, at a former airport in UK 🇬🇧


Our SAFF40 Saffron by EPOC Enviro / OPEC Systems – Environmental Engineering Solutions is back in UK and is just about to start treating our 2nd biggest SAFF treatment project so far. The project is carried out together with Cornelsen Ltd. and brilliant project manager/ general manager Matt Ingram.

Without pre treatment, only using the automatic bag filters, we are about to treat pretty heavily PFAS contaminated canal water, as an important step in the remediation works planned at the site. Works that will create some truly beautiful future residence areas.

A full scale 3 day treatment trial have already been conducted at site, proving the technology efficiency on the complex canal water. The plant sits all blue and ready, awaiting the client to push the start button.

The project will treat all the canal water in the area, and is estimated to be finalised in about a years time. We will, off course (!), follow the project closely and share our experiences, challenges and solutions as always, but off course with the confidential requirements from the client in mind.

So stay tuned! And if you are to attend the Institution of Chemical Engineers (IChemE) global Awards the 14th of November in Manchester, please say hello!

New week, new effective AND inventive treatment tech for removal of suspended particles, PFAS and -yes- Nitrate 😲😳


This is the second set up at these important tunnel drilling works for service tunnel EO2, Stockholm. This time for the professionals at Implenia Sverige AB .

On top of the normal ingredients in the ProcessWater from tunnel drilling works such as Suspended Solids, high pH and nitrates from the blasting, this project passes underneath a landfill collecting PFAS contaminated leachate. It is therefore an impressive set up of effective as well as tight and tailor made treatment systems installed at this site.

But from this week and a couple of months onwards, we have added yet another state of the art and first time in Europe solution – Envytech style. This time for dissolved nitrates.
-And no, it’s no big bioreactor with several steps that is sensitive to everything from temperature to bacteria, solids and other parameters. It’s instead a compact robust treatment step with minimum need of contact time that fits in our ordinary treatment vessels, we just add on an extra reaction tank. And as well as being robust as anything we haven’t seen before in nitrogen removal, it is believed to last for up to 8 years, maybe more.

No, it is not a joke or fake news, but a trial of a new patented product, and a new partnership for us. And a quite massive investment plan for Envytech. It is also, like our solutions SAFF and Rembind, a product of the tireless and pretty unique work that our R&D staff Victor Steffansson and Helena Hinrichsen carries out, with Victor being the proud dad for our nitrogen solution.

As solving the nitrate removal challenges is a BIG quest, it is welcomed by many, and also followed by many in the construction sector. And while we feel the pressure, we have no reason to doubt the solution, but time and results will tell.

We hope to present successful results from this full scale trial at the end of 2022. So to get all updates, make sure to follow us here on LinkedIn. And if you wish to be a part of our journey towards becoming the best in the world regarding PFAS remediation and water treatment for complex waters, send us an email, as we have some awesome work opportunities available.

Friday Cyanide day?! Well this week for sure. Remediation of cyanide and PFAS contaminated water using Chemical Oxidation


Perfectly poisonous photos, by team Envytech technicians Martin Jepsen and Tobias Lindberg at Peab astonishing project site Gasklockan, #Stockholm.

Here some soon to be magic installations will be created, bringing the old gas bell back to life as a cultural venue. But first some old sins needs to be removed, including cyanide and PFAS contaminated water.

Sky blue as well as effective, we here use treatment steps including sedimentation and a media vessel filled with activated glass media for treatment of suspended solids. A following medi vessel with Activated carbon treats PFAS and cyanide, and as finish we apply chemical Oxidation to remove any free cyanide.

Now that’s what we call a potent remedy 🧪👩‍🔬👨‍🔬🧫😎
