Bertfelt Teknik is proud to share with you the latest knowledge about applications with our BT-Maric constant flow valves.

Water is a valuable resource across many economic sectors – and with a limited supply, efficient use of water is an important but often overlooked subject.

You will be able to see here our latest news, videos, webinars designed to give you more knowledge about applications for our BT-Maric constant flow valve and give you insights into the latest trends in the water industry. You can also go to our “LinkedIn” or “Youtube” account to see the latest information.


HOW TO REGULATE THE FLOW RATE OF YOUR APPLICATION PRECISELY?

In collaboration with Vaxa Impact Nutrition, Bertfelt Teknik has developed constant flow valves to achieve optimal results in the culture of microalgae as well as to save water in their production system. Vaxa Impact Nutrition is a high-tech company that offers a solution to convert energy to food (Energy to Food – E2F) in the most efficient way in the world! BT-Maric constant flow valves are designed to give a constant, preset and precise flow rate regardless of pressure variations within a range.

REVERSE OSMOSIS, DOSING OF CHEMICALS, MEDIA FILTRATION, WATER TREATMENT: COSNTANT FLOW OF WATER REGARDLESS OF PRESSURE?

BT-Maric flow restrictors are used in a variety of applications and processes such as reverse osmosis, media filtration and dosing of chemicals. A typical application of BT-Maric flow limiters in water treatment is to control the backwash flow rate and to prevent the loss of fluid in the media filters when the same pump is used in normal operation and for backwashing. Precise flow control is necessary in these circumstances.


UV DISINFECTION IN NON-COLLECTIVE SANITATION

The usefulness of UV disinfection equipment is twofold: to preserve all natural resources by limiting the risk of pollution and to save drinking water. The following article explains the use of UV reactors to disinfect the wastewater then takes up the specificities described by Mr. Willy FORTUNATO, Commercial Director of the company UV GERMI, specialist in biological pollution control by UV and the use of BT-Maric constant flow valves to limit the water flow precisely. To learn more, read the following article published in Aquarama ( in French only).


HOW TO SAVE WATER IN INDUSTRIAL PROCESSES

Business Sweden, together with Bertfelt Teknik AB, EnviroProcess Ozone Solutions, Sweco, Swedish Hydro Solutions, and Weda, recently hosted the webinar “How to save water in industrial processes” to showcase how Swedish smart solutions can help reduce and optimize water consumption – giving second life to one of the most precious resources on Earth.
