- We build water- and waste water treatment plants and we take you through the entire project from design to commissioning with focus on sustainability and efficiency. Malmberg was one of the first companies already in the 1940s that was part of the Swedish water infrastructure build up. Today we commission treatment projects for water demanding industries and for local water authorithies around the world.
Eco-friendly wastewater treatment in Vimmerby
-
Malmberg was commissioned to expand the Vimmerby wastewater treatment plant in collaboration with Vimmerby Energi & Miljö AB.
The plant was previously designed for approximately 90,000 PE but has now been expanded to approximately 150,000 PE to handle both load increases and treatment requirements. Vimmerby wastewater treatment plant receives wastewater from the large food industries Arla and Åbro and also the municipal sewage. During the part of the year when Astrid Lindgren's World is open, the load on the treatment plant is also increased as the park receives around 10,000 visitors per day.
New and self-sufficient in Värnamo
-
Malmberg has built a brand new, complete wastewater treatment plant in Värnamo!
The wastewater treatment plant is built to biologically reduce phosphorus and nitrogen, which leads to a minimisation of the chemical process in the treatment process. The plant includes an inlet section with, among other things, a sand trap, pre-sedimentation, intermediate sedimentation and a filter stage with sand filter.
Pharmaceutical treatment in Linköping
- Sweden's first large-scale pharmaceutical treatment plant in Linköping now inaugurated
In 2016, it became clear who would realise the construction and installation of the new pharmaceutical treatment plant at Nykvarnsverket in Linköping. Malmberg, together with Suez, has carried out the entire technical design and installation. Skanska has been responsible for the construction of the plant. With the help of ozone, it is estimated that more than 90 per cent of the pharmaceutical residues that leave the body can be purified. The ozone treatment plant will be a sub-step in the wastewater treatment at Nykvarnsverket.
Modern and cost-efficient in Orust
-
On the west coast we find the island of Orust with its beautiful Ellösefjorden. The island is Sweden's fourth largest and during the summer months the number of inhabitants triples, which places high demands on the management of wastewater in the municipality. We are currently carrying out a turnkey contract and rebuilding and extension of Ellös wastewater treatment plant. The result will be a cost-effective and modern wastewater treatment plant that meets the environmental requirements of the future!
The Ellös wastewater treatment plant will replace six existing treatment plants. This means that the pipeline system and pumping stations will pump all the wastewater to the renovated treatment plant in Ellös.
Water Treatment technologies - Concepts and products for water treatment
- We work widely with everything from industrial process water, leachate to storm water, household sewage and drinking water. We can offer proven systems and products for different types of purposes.
Airflo®

Our system minimizes energy costs by lowest possible pressure losses, optimized oxygen control and a high aeration capacity. The system is equipped with disc- tube or vertical diffusers.
Malmberg disc diffusor has a diameter of 520 mm and a body of fibreglass reinforced plastic. The rubber membrane is specially designed to resist aggressive environments but also very easy to replace if necessary. The small perforations in the membrane ensures fine-sized bubbles.
- Wide operating range, 1-20 Nm3/h
- Low investment costs
- Low energy consumption
- Disc-, tube- or vertical diffusers
Decanting
-
A Malmberg vertical decanting tube improves the thickening of the sludge by draining the liquid phase under the sludge cover. This means that there will be fewer transports where sludge is to be removed from the plant. Simplifies everyday life and good for the environment!
The decanting unit is available in two different designs depending on whether liquid is to be discharged naturally or pumped. The decanting pipe for pumping is smartly designed with a submerged drainage pump in a collection pipe which is equipped with an integrated rocker for on/off function. In this way you get a continuous decanting of your sludge which works no matter what level you have in the basin/tank.
Plastic Chain Scraper
-
Malmberg Plastic Chain Scraper is designed for use even in extreme environments. The chain is extra strong as well as chemical-resistant which guarantee extra long service life and minimum wear. Each component of the Malmberg Plastic Chain Scraper is very carefully designed.
Precision moulding to extremely close tolerances guarantees perfect form and uniform strength. The scraper blades shaping, made of nylon reinforced with glass fiber, gives it extra long service life. The scraper can be adapted to all usual types of rectangular sedimentation basins either with surface or bottom scraping or a combination of the two. Because it is resistant to corrosive environments, the scraper is especially suited for aggressive waste water and for operations using chemical dosages.
Round sludge scraper
- The Malmberg circular sludge scraper has a combined unique logaritmic/lamella bottom scraping device for optimized sludge transport. It has also a simple but efficient device for removing surface sludge. The scraper is center mounted on a heavy duty bearing either on a framework which itself functions as an inspection bridge or on a conventional concrete bridge. The circular motion is induced through a gear motor.

Suscessful drilling
There are always uncertainties that you can not control in a drilling project. Experience is obviously important, but also that there are procedures and check points. We want our clients to feel secure in the implementation and therefore is the geological feasibility study important. It gives us the answers and what we can expect when drilling. Sometimes a eploration drilling is required to provide further responses to the dimensioning of the well. The well drilling is always done after a given routine and with as little environmental impact as possible. Completion and installtion of the well equipment is always under Malmberg method and according to Normbrunn 07 (Sweden).- Geological feasibility study

Rebuilds and improvements
-
Irrespective of age and function of drinking water wells, they may need a rebuild or upgrade. It may be increased requirements due to the working environment, so that the well can be managed on a service-friendly manner. Or for environmental reasons, to secure the drinking water so that the well installation is not open to undue or to prevent infiltration of contaminants.
Do you have an old well with piping below ground level?
We perform renovation of the well pipes by relining for both rock and filter wells. Old wells have many times piping below ground level and then we can extend the well pipes to above ground as well as upgrade and modernize the entire well installation. New well superstructure provides a secure perimeter and makes servicing easier.
Take the opportunity to upgrade your wells with electricity and automation from Malmberg.
We offer a complete solution for your well with easily foreseeable panel that displays important control parameters and alarm functions. Of course, it can be controlled remotely if you want to, and connects to an overall system.- Flow measurement
- Level- and pressure measurement
- Temperature Measurement
- Speed control of the submersible pump
- Measured values can be read up to higher-level control system, for example MODBus
Furuboda
-
Our Furuboda well superstructure is designed as a small house. It gives the well a perfect protection against weather and external influences on the water supply. Piping, pump fittings and electrical installations are very easy to access and service. The service person can work freely and in hi/her upright position. Furuboda is made of sandwich panels with finishes in different designs depending on the model. Furuboda is also suitable for pumping- and pressure increasing stations or valve chambers.
The superstructure is completely prefabricated and is mounted on a foundation or placed on a gravel bed, alternatively concrete casted. The well will have a excellent frost free spaceing which is easily accessabel by a door. At larger maintenance work as pump chnages the entire superstructure can be lifted of from the foundation. The house is locked and released by hatches on the inside.
Prisma®
-
Our well superstructure Prisma has a simple and modern, perfect for the somewhat smaller well installation. Walls and hatch are sandwich panels with a layer of aluzink on the in- and outside. The insulating core is 40 mm extruded polystyrene. Prisma is standing on a base of aluzink, which is placed on a gravel bed or a concrete base.
Protect your other water installations
Prisma can also be used to protect water reservoirs. The superstructure is then placed above the descent door. It is also suitable for protecting valve installations above ground.
Service-friendly and easy handling of your well installation
The front of Prisma is easily opened by two spring dampers. Here is plenty of room by inspection and service- and maintenance. For larger service work the entire superstructure can be folded backwards and then exposing the installation. The pump- and electrical installation are completely protected from frost and external polution from th surface. The electrical equipment is mounted on a wall panel made of aluminum, 800 x 1000 mm, and is fixed on the base so it remains on its place when the superstructure is folded or off lifted.
Yngsjö
-
Our well superstructure Yngsjö is Sweden’s first prefabricated superstructure and protects wells all over Sweden. It is our original model. It has walls of sandwich panels with layer of aluzink. The insulating core is 40 mm extruded polystyrene. The superstructure is mounted on a base which is placed in a gravel bed. In that way the well is provided with an excellent frost-free spacing, easy accessable.Yngsö well superstructure is developed to melt into the surroundings. Standard colour is in Aluzink. For an additonal price Yngsjö is of course available in other colours. For larger jobs, with the well, such as pump cleansing or pump replacement, the superstructure can be easily lifted aside and work can proceed unhindered.
