Sjöstadsverket treats the wastewater of households and industrial facilities in central Karlstad, Sweden, as well as water from the communities of Skattkärr and Alster. After the water has been purified in the plant, it is released into the Klarälven river, which is a tributary of Lake Vänern.
Sjöstadsverket was built in 1970; more recently, it faced major challenges due to an increased load and antiquated equipment in the mechanical treatment phase. In 2020, Hydria Water delivered an ST30 with accompanying control cabinet to the wastewater treatment plant, which was the largest sand wash the company has ever manufactured and delivered in Sweden. The project also involved demolition, installation, startup, and training relating to the delivered equipment.
Following the successful installation and startup of the sand wash, the Municipality of Karlstad elected to give Hydria Water the opportunity to supply more equipment for Sjöstadsverket. This project involves two mechanical step-type XS 2200-1400-2 screens, which will be delivered and installed during Spring 2021. Hydria Water is assuming overall responsibility for this project, which will include installation, startup, and training, and will thus be able to ensure that the machines are installed and optimised in order to meet Sjöstadsverket’s needs in the best possible way.
– It is very gratifying to have delivered our largest sand wash in Sweden so far, and equally gratifying to having been given the opportunity to supply more machines for Sjöstadsverket’s mechanical treatment phase. Over the past year, we have noticed a sharp increase in interest in our products, Johan Fritz, Sales Engineer at Hydria Water, says.
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.
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.
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.
