Partnering opportunity

Device for removal of hydrogen sulphide and sulphide sulphur from the water


A Czech university developed a device capable of removing hydrogen sulphide and sulphide sulphur from groundwater. The device is designed for normal water flow in households and small and medium businesses. The university is looking for industrial and business partners who would be able to produce and distribute the device and offers license and research cooperation agreement.

Partner sought

The sought partner should be SME from industrial sector. Partner should be able to produce the device and also distribute the product to the final partners, users. Distribution channels and contacts to final customers would be welcomed. The benefits for potential commercial partners include expansion of product portfolio and possibility of addressing new clients.


Developed device is able to remove hydrogen sulphide and sulphide sulphur from groundwater. Hydrogen sulphide and sulphide sulphur occur mainly in groundwater with deep circulation which at one point came into anaerobic conditions. The removal of contaminants is based on membrane process, where contaminants pass from water through pores of hollow fibers membrane, and then are released into the air and led outside of the device. Depending on the location of the device, the contaminants are released directly into the air or are lead from house area to outside air. The device in the form of a construction kit is designed in several basic modules for a variety of practical uses depending on the desired maximum flow rate and efficiency. The equipment includes a vacuum pump. The device is capable of reducing the concentration of contaminants in the water to a level that meets the odor index. The device is designed for normal water flow in households, i.e. approx. 0,2 l.s-1. The spatial requirements enable to install the device in the facility area of the house. The university is looking for industrial and business partners among small and medium companies interested in production and distribution of the device. University offers license and research cooperation agreement and is ready to work together with interested partners on exploratory research or only to transfer the rights for use of device.

Advantages and innovations

The modular nature of the device allows the user to adapt it to the desired maximum flow rate and efficiency. The efficiency of the decontamination process is increased due to the innovative design of the contactor head. This device reduces energy consumption, space demands, price of the final device and operating costs. The main benefit for potential users is improvement in organoleptic properties of water as well as possibility to connect the device to a household water system without losing pressure (case of aeration technologies).

How it works

  • Tell us about yourself
  • We’ll discuss with you
  • We put the right partners in touch

EEN help you find the right partner, rather than you going it alone.

Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.

These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.

Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
