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!

Institution of Chemical Engineers (IChemE) 2022 Global Awards – EPOC Enviro & Envytech are nominated finalists 📸🏆


The first full scale project in the world using a mobile SAFF40 treatment unit was at a leachate site in Sweden, where many PFAS treatment technologies had been evaluated and discarded.

in February 2020 a SAFF40 was commissioned, and has to date treated over 150 000 m3 of leachate, without any pre treatment systems, using approx 0,7 kWh per treated m3 leachate.

– Reaching the target values every month, with average removal rates for long chained PFAS being 99,9% for PFAS4 (PFNA, PFOS, PFOA, PFHxS) as well as for PFDA, 62FTS & PFHpA.

This project was featured in an excellent scientific journal written by David Burns, Helena Hinrichsen, Paul Stevenson and Peter Murphy, presenting SAFF as a PFAS treatment technology for leachate. And it is for this journal, as well as for the SAFF treatment technology that we together with EPOC are nominated for the IChem Water Award. A nomination we applaud the Envytech PFAS team for, as well as EPOC and Paul Stevenson we are super proud for.

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.

Favourite day of the week: Tight Tech Tuesday! Treatment tech with a capacity of up to 40 m3/h on (almost) no space 😳


This is not only a beautiful photo, but a top modern, top notch treatment set up for suspended particles including all from organics to super fines and in all in all, wicked flow velocity on a 2,5x6m surface.
-Yes, it’s true. The two blue buffer tanks to the left and one to the right only serves as tools to be able to pump the water far distances.

The reason this kind of flow capacity is needed at a site like this, is that the client (halleluja) is planning ahead for heavy rainfall events, where the gear have to deliver. Otherwise the site will flood, and create major problems. But ni worries here as we have super smart thinking by Skanska and Envytech project manager Robin Axelson. Always a pleasure working with pros 👌😎

New week, new projects. And how about a seriously complex sludge de-watering project in central Oslo, Norway.


Yes, another project in our Norwegian history book, and this is a really interesting project that we are happy to perform together with super competent and experienced Tore Frogner and Veidekke Norge.

This centrally located project is involving the construction of a a new train station building, and part of the works involves installation of ”pipe piles” 36 m down into the bedrock. While passing the overlaying clay layers, a thick dense #sludge is produced, and this is the sludge that Envytech is to de-water in cooperation with Envidan A/S .

In these photos Victor Steffansson and our VERY well prepared technician Mikael ”Musen” Holm are performing the installation of 4 inch passive mixers, mixer station and pumps for dosing of #flocculation chemicals. The sludge is pumped from the storage container through the mixing station, and the tested sludge is then pumped into 30 m3 geotubs for de-watering. And as it is a really challenging sludge, we will be excited to see the results, and to see if we manage to separate this beast of fine particles and water.

To be continued…

Tight Tech Tuesday. AGAIN.


Lets enjoy with checking out our favourite flocculation and precipitation recipe at the moment.

Another set of particles bites to dust. This as project manager Robin Axelson calibrates the magic for a new project. A procedure we do at the start of every project with suspended particles.

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 🧪👩‍🔬👨‍🔬🧫😎

Meet Robin Axelson, Envytech Solutions AB hero who here checks out late at night after a bench scale SAFF treatment test 🏆🙏🇫🇷


Here we are testing French water sampled from ponds containing water from Have a PFAS contaminated firefighting water from a large fire.

The water is as you see, pitch black from burnt materials and who knows what, but we still treat it without any pre treatments, filter or additives. Samples are handed in, and now it’s just the wait left, but from watching the process, we should have a good result.
-And we will off course show you as soon as we have the protocols in hand. We know you are as excited and curious as we are 😉.

Tight Tech Tuesday? Oh do we have a suitable candidate in this perfect fit water treatment at Snäckan 8, Stockholm.


Yeah check it out. This is a tight effective and nothing short of gorgeous treatment set up transforming complex particle heavy, pH high cement slurry to almost crystal clear water.

The water/sludge is pumped into a buffer tank from where it’s transferred to a compact particle treatment unit adding #flocculation and #precipitation chemicals in a mixer step and where the particles are left to settle out in a lamella step with a #sludge hopper. The water is collected in a buffer container before being released to the recipient.

This job is the very special and prestigious #Snäckan8 by #Sheraton Stockholm for well experienced Skanska and team. A job planned for almost a decade, and labelled one of the most complex construction projects in Sweden.
As always a pleasure working with professionals. These guys almost go under the label Rockstar. An extra high high 5 to our hard working field crew for a smooth establishment 🖐️👌🍾

New month, New SAFF PFAS leachate project. And we are almost nailing removal rates from scratch👌✌️👏


Beautiful mid Sweden project, with a just as expected, complicated PFAS leachate mix. And just as  anticipated beautiful treatment results from our Surface Active Foam Fractionation SAFF developed by OPEC Systems – Environmental Engineering Solutions / EPOC Enviro.
– and off course a just as tight tech set up as planned. The Envytech way, this time by Anders Holttinen.

As always we pump straight from the leachate pond, straight into our pilot SAFF20 treatment unit. Results from the first sample rounds have started to come in, and it is looking good!!
-But can be better. Next step is to evaluate treatment efficiency for each PFAS substance with different treatment times in combination with different energy and bubble settings.
Time for our ”Foam watchers”, as we call our SAFF specialist team, to work their magic.

For more information on the project, the SAFF PFAS treatment method or availability of plants and pilot test, contact our Head of R&D and PFASionista Helena Hinrichsen.

Tight Tech Tuesday – Oh yes we are back. And this time with our first integrated lamella and mixer system size XL 😎🤠


They who say size don’t matter have not seen this absolutely gorgeous, competent, integrated particle separation system for larger flows.

And it’s not only big and effective, it is also super smooth as it is very easily installed and winter protected, as the unit comes in one piece, minimising the need for connecting pipes and hoses.

The little brother to this unit is about to receive a little sister – just wait, but how we have waited for this piece in our puzzle. This as it will have an unique place when washing out PFAS contaminated sprinkler systems, pipe works and firetrucks using PerfluorAd from Cornelsen Umwelttechnologie GmbH .

Want to know more about this work – and all other MASSIVE projects that just landed in our laps –  we have the best clients in the world ❤️, follow us here on LinkedIn or contact Victor Steffansson for infrastructure solutions or Helena Hinrichsen for PFAS remediation solutions for soil, water and installations.

Compact, effective dewatering of construction works in a pond area carried out by ABTK Anläggning AB


Maybe grey skies, but as always, our equipment are shining blue like a summer sky.  Even while treating muddy water filled with particles and dissolved metals.

The treatment train is made up from a buffer container to equalise flow rates, followed by static mixers injecting flocculation and precipitation chemicals in flow specific amounts. The particles are then let to settle in a lamella separator with a sludge collector at the bottom. The sludge is pumped to a geotub for de-watering, minimising the need of vacuum trucks as well as minimising waste volumes. After the lamella, residual rest flocks are collected in a second sedimentation container before the water is pumped to filter vessels for treatment by AIX for dissolved zink. The water is then released to the recipient and meets all target criteria.

Simple, tight, effective and economical. Just the way we like it 👌🌊💦
