Tight Tech Tuesday!!! Tonight’s special: Effective treatment of water/sludge from city close tunnel #drilling works 🚇💦
hello
Deep down below The beautiful capital of Sweden, Stockholm, massive construction works are shaping a new more connected, sustainable and modern traveling system. One of the projects are named Hammarby canal, a future station in the new subway system of Stockholm Nya tunnelbanan, Region Stockholm
We are immensely proud to be water treatment tech suppliers to our competent and professional client Itinera, responsible for the construction for these tunnel works.
This block buster shows of a heavy duty treatment train for removal of #SuspendedSolids#SS using a compact 2-step mixer with automated flow proportional adding of #flocculation and #precipitation chemicals. The solids are left to settle in a lamella clarifier with a sludge hopper, and an automated sludge pump for easy sludge removal. The #sludge is collected in a geotube where it is left to de-water, creating minimal waste that is dry and easy to handle, leaving almost no need for vacuum trucks.
To handle the fairly large flow demand of 60 m3/h, the treated flow is split into two lamellas to obtain enough settling times.
Now THAT is one ⭐⭐⭐⭐⭐Tight Tech set up, and we are as impressed as always, by the work of our top notch technician Martin Jepsen 👌👊
Holy Macaroni! Envytech Solutions to solve the complex water treatment mission at former Macaroni factory in Uppsala.
hello
We are as proud as excited to have been chosen by Forsen AB for the mission to treat the ancient and contaminated water that have been left in the macaroni factory basement, since decommissioning of the plant. The water contains a fair amount of super fine suspended particles as well as dissolved metals.
The treatment plant is set up at Kv. Ångkvarnen starts with a 2-step mixer with automated, flow proportional adding of chemicals for flocculation and precipitation. The sludge is aloud to settle in a lamella clarifier and collected in the sludge hopper at the bottom, from where the sludge is automatically pumped to a geo tube for dewatering. A simple but super effective way to minimize the need of vacuum trucks and volumes of waste.
The particle free water then passes a polishing step of activated glassmedia for that final reduction of particles before entering an ion exchange filter to remove the dissolved metals.
The system can handle flows up to 25 m3/h, and the total volume of treatment is estimated between 2 500 – 5000 m3.
To hear more about project and/or our solutions, contact project manager Victor Steffansson – who is also our #watertreatment design specialist.
Favourite day of the week: Tight Tech Tuesday! Treatment tech with a capacity of up to 40 m3/h on (almost) no space 😳
hello
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 👌😎 #envytechstyle
New week, new projects. And how about a seriously complex sludge de-watering project in central Oslo, Norway.
hello
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 m3geotubs 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.
hello
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.
Tight Tech Tuesday? Oh do we have a suitable candidate in this perfect fit water treatment at Snäckan 8, Stockholm.
hello
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 🖐️👌🍾
Tight Tech Tuesday – Oh yes we are back. And this time with our first integrated lamella and mixer system size XL 😎🤠
hello
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
hello
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 👌🌊💦

Back to the roots! Rening av multiförorenat ”vatten” vid HTE PRODUKTION AB projekt Lilla Backa, Göteborg
hello
Ja men det var ett tag sedan vi fick starta veckan med ett riktigt skitigt schaktvatten. Men såklart såg det inte ut som på den undre bilden från början. Nä, som så många andra gånger visade sig vattnet i början från sin bästa sida, som i den övre bilden, för att sedan övergå till ett medium som mer liknar skit än vatten.
Men vad gör det när man har en uppställning redo för det mesta, och absolut de synder som man misstänkte kunde komma fram här. Men så till lösningen: En tvåstegs mixer blandar flocknings- och fällningskem som tillsätts flödesproportionerligt för maximal effekt. Flockarna tillåts sen fällas ut i en lamellavskiljare, och slammet pumpas till geotuber för avvattning. Det nu partikelreducerade vattnet renas i nästa steg i en filtercontainer med tre seriekopplade filter. Aktiv glasmedia tar hand om ev. kvarvarande finpartiklar, aktivt kol hanterar petroleumprodukter och andra organiska föroreningar, och slutligen renas lösta metaller i ett jonbytarfilter.
Partikelreningen har en kapacitet på 25-40 m3/h, men med filterrening så är det uppehållstiden som styr, och vi klarar i den här uppställningen 8 m3/h. Snyggt, effektivt och pålitligt 👌👌👌 Och apropå det, kolla in designen på pumpgropen vi pumpar ifrån. Det går inte annat än att ge 5 ⭐⭐⭐⭐⭐ till HTE för den väl utförda designen och installationen. Snacka om schyssta förutsättningar för att kunna göra ett bra jobb och hålla kostnaderna nere!
Monday – but free day for the Envytech crew who worked all weekend upgrading the plant at Smedslätt to 50 m3/h
hello
Super proud to once again to have the trust of our very professional client YIT – Urban developer and construction company to be in charge of the water treatment at project Smedslätt. As peak flows are higher then previously expected, the earlier establishment with a 2 step mixer with automatic flow adjusted pH, flocculation and precipitation now flows into two lamellas instead of one, adding double flow capacity. The sludge is collected in the bottom of the lamellas, and pumped to geo tubes, allowing the sludge to dry out, minimizing amount of sludge to be disposed of as well as the need of vacuum trucks.
Mission accomplished, and after some rest the team will be back at it, setting up our new projects, that by the looks of it wil be nothing short of super cool to handle.
Friday sneak peak: On site trial for treating PFAS in drinking water basins, UK
hello
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 🍭🍬😎
