Friday sneak peak: On site trial for treating PFAS in drinking water basins, UK


It’s been a busy week for our PFAS crew. A very interesting on-site trial was carried out at a clients office for treatment of a drinking water source, with camera crew and all, to share the work that is being done with the surrounding community. The trial went as planned, and we are now awaiting the results. A thrilling life for the crew as they have to endure waiting for Xmas presents in the shape of lab reports every week.

The trial was carried out with our UK partners Matt Ingram and Cornelsen Ltd., as well as ATG Group. Stay tuned for updates and results – there are quite a few of those awaiting to be finalized now. Will be like a big candy bag when ready for release 🍭🍬😎

Tingstadstunneln – A state of the art water treatment plant handling up to 60 m3/h of complex multi contaminated water


And so the establishment is finished, and the first volumes has passed through the system, and the initial samples controlling the effectiveness of system removal of suspended solids, metals, petroleum products, nitrogen, phosphorus and pH have been collected. A service carried out by Envytech staff as apart of our full service offer, making tuning, correction, design of flexibel solutions and contact with authorities as smooth and time/cost effective as possible. This as we see the water and possible changes straight away, maybe even before lab results have come in, and stay updated on changes in the clients work activities.

We use flocculation and precipitation in combination with lamella separators to remove suspended solids and particle bound metals. The water is then polished of in a mineral filter offering leading performance on fine particle removal.

All sludge and backwash is passed through a geotube draining the wet material, minimizing the need of sludge removal by vaccum trucks.

All packaged and labeled in true blue Envytech manner. An Envytech line galore one could say, and neither we or our super professional client Peab can srop smiling as you glance upon the gear.

One proud as team, we can tell you 👌👏🌊

For information on the project, please contact our hard working project manager Anders Holttinen or our Head of designs Victor Steffansson

Dewatering of dredging sludge, treatment of reject water, Södertälje


And so it begins. Envytech are super proud to have been awarded the treatment works for treating reject water from dredging materials from the Södertälje harbour.  Installation works are just about done, and we are ready and set for action.

Treatment set up is mixer, flow proportional adding of flocculation and precipitation chemicals, pH adjustment by CO2, lamella separator, sed. container and geo tubes for dewatering of reject lamella sludge. Chemicals in different combinations and concentrations has been trialed, and as can be seen from an earlier post. We are home baby!

This combination will be used to treat particle heavy water by entering into a two step mixer with automated injection of chemicals and CO2, and particles are then left to settle in lamella separators, collection of the sludge is carried out in the bottom cone of the separator. Sludge are then pumped into geo tubes for final dewatering.

To be handed such a complex challenge as this is, solely based on our reputation for offering high quality water treatment plants with full service agreements, thick icing on the cake. Including the figures on top 🎂👫.

Start up of new PFAS leachate remediation trial using SAFF – and this time using our new world first SAFF20 treatment plants


First of two new #SAFF #leachate treatment projects established. And we can’t wait to see how this leachate will foam and how to optimize treatment.
Our super knowledgeable crew Anders Holttinen and Johan Lindahl, and of course Jamie Sheargold from EPOC, who is living the life of Vikings with horizontal rain/snow and icy degrees helping us with the initial commissioning of the units, making sure they work as expected.

Treatment of leachate using SAFF has been a journey filled with experiences and challenges, but we are getting really good. And as we now also have projects in UK with even more challenging water, that we seem to be able super well, getting amazing PFAS removal, and we think it’s fair to say that we have come a long way. Which feels good not only for the projects themselves, but also for the environment as we now have a sustainable PFAS remediation option. And that to us is cool for real. And a change for real 👌🌍♻️

Alright! Another PFAS treatment project using only air


No consumables, only offered by SAFF – Surface Active Foam Fractionation by EPOC Enviro / OPEC Systems – Environmental Engineering Solutions, a solution provided by Envytech for the European, Scandinavian and UK market.

Envytech has to date 3 ongoing PFAS leachate treatment projects in Sweden, and as we are starting up this full scale system to perform a 3 month pilot project, we have 4. So far we have treated almost 120 000 m3 of leachate, with 100% of control samples meeting site criteria. And as early adapters we now have the largest SAFF rental fleet on the world market – proving the technologies robust and unique capabilities, and more units are coming as we are to start up projects in the Netherlands, France, UK and more.

Malmökontorets första projekt klart. Rening av komplext pannvatten förorenat med PAH:er, oljor, PCB och metaller


Ja nu är de igång på riktigt, Envytech Malmö, under ledning av Michelle Nilsson. Och vilket fint projekt det blev. Kunden Dalshult Industri & Entreprenad AB  är jättenöjd och konsulten från Kodeda Konsulter AB, ansvarig för provtagning och myndighetskontakter, likaså. Och det pratas redan framtida samarbeten. Michelle höll heller inte tillbaka på de fina orden över hur kunden medverkat till det lyckade resultatet. Det är sådana här samarbeten som vi brinner för.

Projektet omfattar #vatten i två kulvertar i en källaren på ett gammalt mejeri, varav den ena är en panncentral. Reningsanläggningen omfattade ett Kemskåp för flödespropportionerlig tillsats av fällning och flockningskem, mixer och en lamellavskiljare där partiklar och susp fälls ut. En 38 m3 sedimenteringscontainer tar hand om ev restflockar och fungerar även som pumpcontainer. Vattnet pumpas härifrån till en filtercontainer med tre filterbehållare, där vi för det aktuella vattnet använder mineralmedia för effektiv putsning av finpartiklar – sand är från dåtiden. Nästa filtersteg omfattar aktivt kol och vi avslutar med jonbytare.

Med denna uppställning renar vi samtliga kontrollerade parametrar, #aromater, #alifater, #BTEX, #PAH, #PCB, #metaller och susp ner under aktuella riktvärden.

Vi renar med ett flöde av ca 5m3/h. Utsläpp påbörjades 13/4 i samråd med ledningsägaren NSVA

För mer information om våra möjligheter i Malmö – ja de är ju samma som i övriga Sverige, men presenteras lokalt av Michelle Nilsson . Det går såklart även bra att kontakta vem som av våra duktiga projektledare. Men för skånsk dialekt gäller Michelle 😎

Friday – OH MY!! 😲😲 Day at the Envytech casa. All new gear that just arrived is already leaving for new projects


Beautiful weather, beautiful gear and their presence is a ”memory blue” as we once again run out of gear until the next deliveries arrives in a couple of weeks. It’s definitely a luxury problem – but still a problem.

Projects starting up next week – we kid you not 🚀🏎️💨

➡️ The renovation of Tingstadstunneln, Gothenburg – WHAT a project! and how we have waited 👏📢👌
➡️ Barkarby Staden, Stockholm – Now that is some FAT tech going there to become two massive treatment stations for #PFAS and particles.
➡️ Treatment plant for reject water from dredging materials, Södertälje Canal.
➡️ An HELLO treatment plant for the water produced by planned #tunneling works for project #Arenastaden, Stockholm.

And with that, we take weekend. Need to stock up on energy 😎😅🤟.

Tingstadstunneln ska renoveras, och vi ser fram emot att på uppdrag av Peab ställa upp en styck riktigt snygg ”Envytechlina”


Då renoveringsarbetena kommer omfatta #vattenbilning, kommer vatten från processen att omfatta partiklar, färgflagor, cementdamm, lösta metaller så som #krom6, partikelbundna metaller och petroleumprodukter. Det är ont om plats och vår s.k. Envytechlina är därför perfekt.

Installationsarbetena börjar i veckan. Vi kommer så klart följa upp arbetet här med bilder och resultat. Dags att göra Göteborg lite renare, och lite blåare 🙂👌

Snyggt och spännande projekt där vi som stolt leverantör har ansvarat för vattenrening av borrvatten från start!


Ja det är som Erik säger. Det har varit en spännande resa, och som nästan alla projekt så bjuder vatten på utmaningar i takt med att projekten når olika etapper.

I dagsläget omfattar vår anläggning partikelrening och pH justering, men då arbetena nu går in i nya faser, så håller vi tillsammans med CRTG på att utvärdera om ev. uppgraderingar skall göras för att möta kommande behov. Vi ser fram emot fortsättningen och att få jobba vidare med detta duktiga team samt att få dela med oss av resultat och lösningar även från denna etapp.

Evaluation of treatment recipe for de-watering activities for dredging materials!


Wow – lucky finding the right treatment design for this dredging material wasn’t as hard as reading that sentence 😅.

But more seriously, we Envytech, are super proud to have been awarded the treatment works for treating de-watering water from dredging materials, for an upcoming harbour dredging project .  A project carried out later this spring, but preparations have already started.

By obtaining a trial sample from the planned works, we are here evaluating several flocculationprecipitation chemicals in different combinations and concentrations. And voila! We have a winner 🏆 – see the action packed movie below 🎬💥📽️

This combination will be used together with an Envytech signature ”lina” (set up), where we let the particle heavy water enter a two step mixer with automated injection of chemicals and CO2, and particles are then left to settle in lamella separators, collecting the sludge in the bottom cone. sludge are then pumped into geo tubes for final de-watering.

To be handed such a complex challenge like this, solely based on our reputation for offering high quality water treatment plants with full service agreements, is icing on the cake. Including the figures on top 🎂👫.

Stay tuned for project specifics, sexy tech photos and seriously competent gear.
Soon in an update near you 😎👌
