School students undertake work experience at Hydria Water

Linn Broberg and Elliott Eckerström elected to continue their high-school studies with a fourth, technical year at Sven Eriksonsgymnasiet (‘Sven Erikson High School’) in Borås, Sweden. Over the course of the spring they spent a number of weeks with us at Hydria Water undertaking work experience in order to strengthen their theoretical knowledge through practical learning.

Their primary task during this period was to update the information material of many of the articles and components that are used in our products. This involved re-drawing existing two-dimensional drawings as three-dimensional ones, which will be used in our new, shared file management system. This task was vital to our internal preparations for merging the Group’s operations, and allowed the students to put the skills that they have learned at school to the test and further develop them.

Both Linn and Elliott have done great work here at Hydria Water, and we are delighted that they will return for a few weeks during the summer.

Hydria Water safeguards the wellbeing of its staff

At Hydria Water we have a strong belief in the importance of the wellbeing of our staff and we feel that a key part of this is ensuring that people feel able to take an active break and engage in exercise while at work. This is an ethos that the Hydria Group has actively prioritised since 2017, and is a broad, long-term, and active focus across all of the companies of the Group. The project is entitled Hydria Må Bra (Hydria Be Well).

– The purpose of the Hydria Må Bra project is to increase motivation to engage in beneficial everyday exercise through a wide variety of activities such as organised cycling events and lunchtime walks. This is intended to increase enjoyment of the working day, Tor-Björn Danielsson, CEO of the Hydria Group, says.

In addition to improving the health of our staff, the project is also intended to ensure that, in spite of the different industries and cities in which the companies of the Hydria Water Group are active, the Group as a whole is brought closer together. Some activities are planned for individual companies, while others are Group-wide or can be attended by all Group employees in a given city.

During Spring 2021, the activities included walks, lectures, and events such as mountain biking.

Multi Rake Screen ensures the productivity of Skellefteå Kraft’s pumping station

Skellefteå Kraft is one of Sweden’s five largest electricity producers. The lack of a protective screen for large particles at the inlet of Skellefteå Kraft’s pumping station in Hedensbyn, Sweden, has led to recurring production stoppages over the years. During the project, Hydria Water has worked closely with the projected consulting firm to find the best technical solutions for the facility.

The Multi Rake MR screen that Hydria Water delivered is roughly 10 metres high and 800 mm wide; it has a slot width of 6 mm and so is one of the tallest Multi Rake MRs manufactured in the factory. Because of the narrow space in which the screen was to be installed, it was delivered in three parts. In connection with the project, Hydria Water was responsible for installation inspections, start-up, and the training of staff in the use of the delivered equipment.

– Thanks to our modern machine park and specialised personnel, we have been able to design our Multi Rake MR screens so that they can be installed in sections. It is with great pride that we have built this seemingly simple but in reality very complicated screen for water in which there are no fat particles, Johan Fritz, Sales Engineer at Hydria Water, says.

Thanks to our many years of experience of adapting machines for narrow spaces, this was a project that Hydria Water was well suited to.

Hydria Water assists Mixum in decreasing their environmental impact

In north-eastern Motala, Sweden, Mixum’s state-of-the-art production facility prepares, among other things, quinoa salads, pasta, and eggs for Picadeli’s salad bars, which can be found in food stores in Sweden, Finland, Denmark, and Central Europe. Picadeli are currently the largest supplier of cooked pasta and pasta mixes on the market. In a single year, they produce no less than 3000 tonnes of cooked pasta, which corresponds to 150 large trucks.

Care for the environment is a strong priority for Mixum, and the company has introduced a large number of production-related measures to decrease their impact on the environment.

– The industrial production of bulgur and pasta dishes involves the use of large quantities of fat, which is disposed of along with wastewater. It is for this reason that we built an entirely new facility with new machinery, which became operational at the end of November last year, to deal with the problem says CEO Magnus Frantzén.

In 2020, Hydria Water delivered a Drum Screen RS with a horizontally mounted drum to filter solid particles from the process water, and a conveyor for dewatering the particles. Mixum chose to use Hydria Water’s services on the basis of a recommendation.

Hydria Water expands it’s operations in Borås

As a result of an ever-increasing demand for water treatment products, Hydria Water has identified a need to invest in and consolidate its brands. At the moment, production is being moved to and concentrated in the Viared industrial and logistics hub in Borås, Sweden.

Through its brands Mellegård & Naij and VA Teknik Sweden, Hydria Water has previously undertaken production work in both Viared and Skövde, Sweden. As Mellegård & Naij has outgrown its facilities in Skövde, production will be moved to Borås in order to consolidate the company’s supply chain and production facilities in one place.

– This allows us to be more flexible in our production and allocate our resources based on the requirements of our different product ranges. We see that demand for our products has increased strongly in both Sweden and internationally, and that we need to concentrate our efforts and focus on one place in order to ensure faster deliveries, CEO Robert Bjursten says.

The move will commence in April and conclude in September of this year. Some of the staff will relocate to Borås, and at the same time a new competence centre consisting of salespeople, sales support, and engineers will be created in Skövde. In total, 10–15 new jobs will be created in Borås.

– Our facilities in Borås are spacious, well-equipped, and perfectly placed to make the most of our logistics and transportation network. This is part of the largest investment in the history of Hydria Water, and part of our overall effort to build our brand, Robert Bjursten says.

Ellen Gremo, the newly appointed Marketing Manager at Hydria Water, provided further details on the plans:
– This is the beginning of our large-scale brand work that will be carried out during the autumn.

Hydria Water collaborates with the mountain villages of Storlien and Bydalen

Over the course of 2020, Hydria Water delivered and installed a new wastewater treatment plant in the village of Bydalen in Åre municipality in northern Sweden. The municipality is now continuing in the same vein by building another in the village of Storlien.

The existing wastewater treatment plant has reached its maximum capacity, and an investment in a new plant is a crucial step in maintaining the municipality’s current rate of development and attractiveness as a place to live and visit. Because of this, all local development plans and expansions have been put on hold for the past five years. The building of the new wastewater treatment plant is an important event for both Storlien as a village and the municipality as a whole with regard to continued development of housing and infrastructure.

The project will be almost a carbon-copy of the one in Bydalen. For both projects, 3D construction software was used to support communication; this facilitated communication to a very high degree, as is shown by the results of the first project.

– The communication between the commissioner, project manager, project planner, and machinery supplier has been greatly facilitated by the 3D construction process software. When our partners have needed to make changes to the plan, we were able to communicate these based on a common understanding of the state of the project in order to optimise installation and assembly times. We have made best possible use of the various partners’ competences in order to achieve as successful and efficient an installation as possible, Andreas Riedel, CTO of Hydria Water, says.

The new wastewater treatment plant in Storlien will have a similar tank design and the same number of sludge scrapers, scum pipes, and outlet weirs as the one in Bydalen. Assembly and installation will be carried out in May/June 2021.

High-quality Swedish manufacturing and sustainable solutions within the Hydria Group

At Hydria Water, we believe in high-quality Swedish manufacturing and sustainable solutions. These watchwords are shared by all of the companies in the Hydria Group. The group has a strong focus on the environment and was founded in 1994, and since then has strongly invested in the development of the business areas of Water, Forest, Ventilation, and IT & advertising, resulting in a great deal of success. We are both proud and grateful to be part of such a well-established group which has strong values and a leading position on the international market. 

One of the many strengths of being part of this group is that we are able to exchange a great deal of personnel, information, and ideas between the companies, because as whole we possess a wide array of knowledge of different industries. Over the years the development of water-purification solutions has progressed, and much of this development is owing to the well-established group behind Hydria Water. We continue to look to the future and are now working to lay the foundations for further innovation and take the next step in our development journey.

The Hydria Group’s strategy for the future is to continue to grow through the use of modern production technology, innovation work, product development, and well-adapted facilities. Our long-term goal is to become an innovation group that works with new materials and the idea of a circular economy. Together, we are working towards a better environment, a better and safer indoor climate, and a cleaner world.

Large-scale investment in the Baltic Sea

The Käppala wastewater treatment plant on the island of Lidingö, off the coast of Stockholm, currently treats the wastewater of over half a million people. Now, a large-scale investment to increase the plant’s capacity and create a cleaner Baltic Sea is made.

Over the next seven years, the Käppala Association will modify and upgrade the current wastewater treatment process in order to meet higher requirements and increase capacity so as to be able to treat the wastewater of greater numbers of residents. Hydria Water has been selected as a supplier, and will deliver chain scrapers and scum pipes for the Käppala plant’s clarifying tanks.

– We delivered chain scrapers to the Käppala plant eight years ago. The client was very satisfied with the installation and the systems that were delivered then, and we have had close contact and a good working relationship ever since. When all of the new chain scrapers have been delivered in 2023, we will have provided a total of 32 chain scrapers, which we are very proud of, Johan Fritz, Sales Engineer at Hydria Water, says.

The Käppala Association’s facilities are situated below ground in large rock shelters in the Käppala district, on the eastern part of Lidingö. The wastewater of roughly 500,000 people is carried to the plant via a 60 km-long tunnel system. At the plant, the wastewater of households, schools, industries, offices, and hospitals is treated. Sludge, phosphorus, and nitrogen are removed from the wastewater through mechanical, biological, and chemical treatments. The process takes place in several steps, and it takes one to two days for the treated water to be released into the Baltic Sea.

Between 2021 and 2027 the plant’s entire wastewater treatment process will be upgraded, and complemented with new technology in a new configuration. This will facilitate the removal of even more nitrogen, phosphorus, and organic pollutants – while at the same time increasing capacity.

– It is one of our largest ever projects, Johan says.

The project will be carried out in stages in order to allow the plant to remain operational; at present the first stage of the installation work is being undertaken by Hydria Water.

Creating the servicing organisation of the future

In order to be able to offer our clients the best possible service, Hydria Water is investing in and creating an entirely new servicing and aftermarket department. Our new additions Jörgen Edelmalm and Peter Rosén Tengling are directing these efforts, and both have long experience in servicing and technology.

– There is a great potential in the aftermarket for these kinds of products. Our new servicing organisation is our way of preparing for the future and will ensure we are able to provide world-class service!

Jörgen Edelmalm has the role of Service Coordinator at Hydria Water; he previously worked as a workshop manager at Processmodul and ELVA ProcessAutomation AB, both located in Motala, Sweden.

– I’ve installed both VA Teknik Sweden’s and Mellegård & Naij’s products in the past, and know the brand well. I enjoy working in this industry as I feel that it produces high-quality products and think the people are great to work with. My primary motivation is developing an organisation and being a problem solver – that’s something I’m passionate about, Jörgen says, and continues:

– The client should not have to contact us; we should anticipate their needs and set up a structure to prevent production delays by, for example, digitalising processes.

Jörgen is based in Motala, where he and the newly recruited service team have moved into new offices on the premises of Rasch, which is part of the Hydria Group. At present the service team consists of three people, but the plan is to expand the team and recruitment is ongoing.

Peter Rosén Tengling began his tenure as Aftermarket Manager on October 1, 2020, and works closely with Jörgen.

– We are carrying out this mission together, as a team – Jörgen has an enormous amount of experience! My role is working from a long-term perspective, building up an entirely new organisation, and having overall strategic responsibility.

Peter has worked in sales throughout his professional career. Between 2006 and 2013 he ran his own company, Roséns glascenter (‘Rosén’s Glass Centre’), which was sold to Ryds Glas, to which he provided consultancy services in public procurement.

– I had heard a great many positive things about the company, and that the Hydria Group has strong foundations. My goal is for us to be the first choice on the marketplace when people are looking for excellent service, regardless of machine and supplier. Now, we are preparing for the future, and want to ensure that we are able to provide world-class service!

New rotating distributor handles up to 70% more strain and stress

At Hydria Water, work is constantly ongoing on the innovation and development of working methods and products for the future. When one of our clients experienced unforeseen problems with a rotating distributor and needed a more robust machine due to strong winds, the engineering department designed and built an entirely new heavy-duty rotating distributor.

– It was designed to be able to withstand both high winds and uneven loads. We have developed the design to have, among other things, a new top layer, and a created a machine that can handle 60–70% more strain and stress with the same component costs, Andreas Riedel, Technical Manager at Hydria Water, says.

Andreas explains that the engineering department works as a team; they first sketch proposals for products that they wish to create and then model them using simulation software. They then discuss their design, and following consultation with the client go forward with one of the suggestions – in this case a prototype heavy-duty rotating distributor, which has been installed and operational for a year at a wastewater treatment plant in Gnosjö, Sweden.
