The case studies on this page are a spectrum of Pursanova DiskTM applications explaining what can be achieved, how it is measured and proofed.
These are examples of applications from scaling, corrosion, fouling, and biofouling, in all kind of industries or commercials.
Most of these applications, have been successfully realized several times and we have equipped not just one oil refinery or just one steel plant, but several of them. On ships, for instance, Pursanova DiskTM has solved innumerable applications, and we will soon present a list of the vessels together with a picture of the same. The cases presented here have been either the first one of its kind done by Pursanova DiskTM or projects which are documented in a way which is presentable on the web.
In some of these case studies, you will find written testimonials from our customers, which are there in their original format. There are also several missing applications where we didn't get permission from our customers to talk about their projects like applications in power plants, or other sensitive industries. Behind the table is a very powerful database. We will over time make use of this database and will add the possibility to select branches, countries or the type of liquid, and you might be able to search inside these case studies for a specific problem you are facing.

Also on this page, you will find some calculation tools. There is a tool where you can calculate the possible savings of water and money when using Pursanova DiskTM in a cooling system. Another calculation tool, we found so important is the Heat Transfer Coefficient tool. Pursanova DiskTM is using this internally a lot to check the fouling in a heat exchanger. We decided to make this available to our interested clients or students so they can make use of these tools as well.
