Your long-term partner in water treatment

Hydria Water is a long-term partner for sustainable operations in water treatment processes. Through close collaboration and dialogue, we provide our customers with complete solutions adapted for each process with focus on quality, security, and service.

With our own production, high competence, and a great willingness to innovate, we guide and help businesses with mechanical water treatment, and thus become a part of transforming wastewater into a resource.

The merger of VA Teknik Sweden and Mellegård & Naij with Hydria Water brings our entire offering together and creates even better conditions for us to be able to help our customers succeed with sustainable water treatment processes.

Hydria Water upgrades Finspångs Tekniska Verk

Finspångs Tekniska Verk has expanded the capacity of its pre-treatment application at the Axsäters wastewater treatment plant to live up to the current flow requirements.

The new application is able to handle 2000 m3/h. Hydria Water has partnered up with Aquasvea and supplied two step screens, two screw presses, and two shredders with the accompanying control cabinets. When installing the new pre- treatment application, Hydria Water’s mobile container solution was used to carry out operations temporarily. Hydria Water was also responsible for assembly, deployment, and training of the delivered equipment.

Development of efficient sludge management together with AVVATech

Following an earlier successful collaboration with AVVATech, the customer reached out so that we could jointly develop a solution for sludge treatment for their end customer.

– We have ordered conveyors from Hydria Water before and been very satisfied, therefore, we reconnected to begin a new collaboration for further efficient solutions, says Andreas Lindström, constructor at AVVATech.

The conveyors are used for transporting dewatered sludge, and with the help of electronic actuators, the sludge is distributed evenly in a container. Sludge management done sustainably and efficiently – a part of the water cycle.

Maintenance Agreement for a sustainable future

We always strive towards being a holistic partner for our customers and to offer sustainable solutions. Therefore, we have developed a Maintenance Agreement, which encompasses both existing and future customers, projects, and installations, in accordance with which we perform maintenance and repairs in order to prevent sudden outages. This also prolongs the lifespan of the machines.

Along with this, our aftermarket team is always on sand-by to provide our customers with their service and expertise to create a more sustainable future long-term. We are always close at hand, and you are more than welcome to contact us if our Maintenance Agreement sounds like something that would interest you!


Hydria Water renovates and improves the efficiency of Arboga wastewater treatment plant

An extensive renovation is currently ongoing at Arboga wastewater treatment plant, which purifies up to 6,000 cubic metres of wastewater every day. After winning a public procurement contract in Autumn 2021, Hydria Water is currently manufacturing and installing new machines for the wastewater treatment plant in collaboration with Ståthöga MA Teknik. Hydria Water is responsible for supplying and installing new plastic chain scrapers, while Ståthöga MA Teknik are repairing the concrete in the sedimentation tanks.

The renovation of the plant will improve the efficiency of the sludge-removal process, as old, cabled-pulled carts will be replaced with a plastic chain-scraper system. It will also result in the wastewater treatment plant’s operations being more reliable and energy-efficient. This is a large project with a focus on sustainability, and will ensure that the wastewater treatment plant can continue to work in an efficient, environmentally friendly, and hygienic way for many years to come.

A merger that makes things easier for our clients

One of the reasons for the ongoing merging of the Hydria Water, Mellegård & Naij, and VA Teknik brands is to simplify things for our clients. Before we began this process, several different parameters were carefully considered in relation to the needs of our clients.

– Today, our clients have one way of contacting us instead of several, which we believe makes everything easier. They are now able to purchase products and services from a single company rather than several, Robert Bjursten, CEO of Hydria Water, says.

By gathering the many strands of the organization and integrating our systems and processes, we are now creating a modern and attractive company that is always there to meet our clients’ needs.

New wastewater treatment plant to be built from the ground up in Nora Municipality

The existing wastewater treatment plant was built towards the end of the 1950s, and parts of it have been expanded and rebuilt over the years.
In order for Nora Municipality to grow and additional areas to be connected to the municipal wastewater treatment system, it was decided that a new wastewater treatment plant needed to be built. The new plant will be placed next to the existing one, allowing the old plant to continue to operate until the construction of the new one has been completed.

While the tanks in the old plant are uncovered, the new plant will have a roof that will improve the working environment considerably. As the roof will also reduce problems related to unpleasant odours and noise, the negative impact on the surrounding area will be significantly reduced for the new plant.

ELVA ProcessAutomation AB has entered into a partnering agreement with Samhällsbyggnadsförbundet Bergslagen (‘The Bergslagen Association of Local Authorities’) for the construction of the new wastewater treatment plant. In turn, Hydria Water have signed an agreement with ELVA ProcessAutomation AB to manufacture and deliver plastic chain scrapers, scum pipes, and outlet weirs for five clarifying tanks.

The construction process began with excavation work at the end of 2020, and is projected to be completed in Summer 2022. The machines are currently being manufactured and will shortly be installed by Hydria Water.

Energy-efficient chain scrapers for FORS A/S in collaboration with Krüger

In close collaboration with Krüger, we recently manufactured chain scrapers for the Danish utilities company FORS A/S and the Bjergmarken wastewater treatment plant outside Roskilde, Denmark. The old chain scrapers, which were also manufactured by Hydria Water (then VA Teknik), were worn out after 25 long years in operation; the new ones are made of plastic, and have been paired with drive motors with a plastic chain transmission.

– The new scrapers are efficient and require almost no maintenance. Thanks to their low weight a smaller drive motor can be used, which in turn requires less power. This makes the solution more energy-efficient, Søren Juul Hansen, Sales Manager at Krüger, says.

As Krüger is certified according to the UN’s sustainable development goals, all of the involved parties were required to meet high sustainability requirements throughout the replacement process.  Thanks to our products being of very high quality and having very long lifespans and our constant focus on the development of components, Hydria Water fulfilled these requirements.

– We have, for example, decreased the amount of plastic used in the wearshoes by 45%, without shortening their lifespan. The product thus contributes to the companies’ sustainability efforts in terms of circular economy, which is of huge importance to us, Ellen Gremo, Marketing Manager at Hydria Water, says.

We want to thank FORS A/S and Krüger for a productive and interesting collaboration which focused on sustainability and energy-efficiency, and produced a successful end result.

Hydria Water to become Hydria Water – all of our brands are coming together under one name

For more than 30 years, we have worked for cleaner water. We are in the process of bringing together VA Teknik Sweden, Mellegård & Naij, and Hydria Water under one name, with shared production facilities. We are becoming better together!

The cooperation between our companies has always been strong, and earlier this year we moved our production facility in Skövde to Borås, Sweden. At the same time, a new competence centre consisting of salespeople, sales-support personnel, and technicians who work closely with the head office in Borås was created in Skövde.

The combining of all of our brands under one name is a natural evolution that will ensure efficient cooperation and continue to make the most of our shared competence and innovation culture. At the same time, it’s simplifying the business for our customers and suppliers. With world-class production and a modernised and expanded product range, we stand ready to face the demands of tomorrow and continue our water-purification efforts.

The change of name will come into effect on January 1, 2022, but some changes will take place from December 1, 2021 onwards.

In detail, the merger and change of name mean that VA Teknik Sweden will change its name to Hydria Water, and the sales company formerly known as Hydria Water along with Mellegård & Naij will merge with this company. In practice, the transitional period will last between January 1 and May 1, 2022, when the merger will have been finalised. Hydria Water’s business information will then be as follows:

Hydria Water AB
P.O. Box 858
SE-501 15 Borås, Sweden
Head office: Ödegärdsgatan 4, 504 64 Borås, Sweden
Phone: +46 (0)33-23 67 00
Competence centre: Kåsatorpsvägen 9, 541 34 Skövde, Sweden
VAT no.: SE556470932601
Org. no.: 556470–9326

We are really looking forward to this new chapter in our history. If you have any questions or queries don’t hesitate to contact us.
