Effective water purification with Hans Buch’s wide selection of quality products
Complete range secured Hans Buch the order for Split Water Nordic’s unique application, which ensures efficient water purification of pesticides and PFAS centrally at water supply facilities and decentrally in new constructions.

Split Water Nordic is a scalable and flexible solution for water purification
Hans Buch’s wide range of technical solutions has enabled Split Water Nordic to assemble a program of components and products from one supplier, where quality, customer service, and delivery times are top-notch.
Split Water Nordic’s concept is a scalable application for both central and local water purification. The scalable concept allows the solution to be adapted to everything from larger, central water supplies to smaller, local projects with new construction of apartment buildings.

The application is also space-saving and energy-saving compared to competing solutions. The concept therefore enjoys great interest and demand, which, in addition to the adaptation options, provides effective purification of pesticides and PFAS.
The Challenge: One supplier for a total solution with European goods
Split Water Nordic was looking for a central solution for deliveries of products and components that could reduce the number of suppliers for the many different technologies used in the application. Here, the choice fell on solutions from Hans Buch’s categories, including pumps, instrumentation, and valves.
At the same time, the selection had to be of high quality, and it is precisely here that Hans Buch’s multifaceted areas of expertise and wide quality range have become the best solution to the customer’s demand. Additionally, the requirement is that the components are produced locally or regionally with European manufacturers and suppliers.
– At Split Water Nordic, we have focused on good and durable components throughout the process chain. We know Hans Buch as a stable supplier and with a prioritization of quality goods that can be scaled according to our needs, explains project manager at Split Water Nordic, Alex-Sander Martin Christensen, and adds:
– Additionally, we focus on ensuring that the components contribute to our application being space and energy-optimized, so we have gone for products that have high performance in the smallest possible space and with the least possible energy consumption.
The Solution: A unique combination with a complete range from Hans Buch
Hans Buch’s complete range has ensured a solution where Split Water Nordic only needs to go to one place for a range of components that constitute vital parts in the application.
The range consists exclusively of products from European suppliers and includes, among other things:
Pumps from SAER
Italian SAER Elettropompe S.p.A. is Hans Buch’s supplier of pump technology and has delivered monoblock pumps of the type IR including motors for the application.
Instrumentation from KOBOLD
From German KOBOLD Messring GmbH, Hans Buch has delivered a range of different instrumentation technologies for the application: Flow and level meters, transmitters and switches, as well as pressure, pH, temperature, and turbidity.
Valves from OMAL
Italian OMAL is behind the stainless steel valves that Hans Buch has delivered to Split Water Nordic’s water purification application with electric actuators.
This case is one example of many where Hans Buch helps customers with unique solutions by providing technical advice and assembling products and components from our skilled specialists, explains CCO and division director for Hans Buch Industry, Rasmus Pedersen.
– Our deliveries to Split Water Nordic, where we have brought our broad technical knowledge and range into play in the concept phase, provide the customer with a total solution for a unique concept, which we are proud to be a part of. We are pleased with the growth journey that Split Water Nordic is on, and we look forward to the continued close cooperation, he says.
The Result: An easy scalable solution with fast deliveries of stock items
The result is a unique composition of Hans Buch’s quality range for an application that challenges the market with more efficient purification with less water waste, and which uses 70% less space than conventional solutions.
The collaboration between Hans Buch and Split Water Nordic has led to a complete product portfolio for the customer from one consolidated supplier with good customer service and fast deliveries from stock items.
– We have gone for a supplier who could offer us a complete range of products for what constitutes our unique application for water purification systems, says Alex-Sander Martin Christensen.
– Hans Buch’s expertise, good customer service, and fast delivery times make them a stable and good partner for us. We experience a quick response and fast delivery times on the products we request, and this enables us to deliver our finished concepts to customers both in Denmark and abroad, he concludes.




Perspective: Swedish project sets new standard for new constructions
Split Water Nordic’s application finds its place in the efforts for solutions that contribute to climate and environmental emissions. The company has delivered a complete solution to the Swedish project Rewaise, which is supported by the EU’s research and innovation program Horizon 2020 for inspiration throughout the European Union.
In Sweden, new legislation is on the way that requires the collection and use of surface water in new constructions. Split Water Nordic’s concept is installed locally under the apartment building for purification and use as secondary water for, for example, baths and toilet flushing.
