Partnering opportunity

Innovative device for activation of water used for plant spraying.


A university from Latvia has developed a cost-effective water activation for plant watering/spraying device. The device is mainly foreseen to be used in greenhouses. The university is offering commercial agreement with technical assistance to agricultural equipment producing companies.

Partner sought

Type of partner sought - equipment for agricultural applications manufacturers/suppliers. Role of partner sought – adapt/produce water activation devices/offer the technology of water activation to their clients.


An electrical current running through salty water creates a mixture of chemicals that kills microbes such as bacteria, fungi and viruses. The mixture is called ‘electrolysed water’, but the process - anodic oxidation. There are many other names for electrolysed water, including, hydrolysed water, electrically activated water, electrochemically produced water, activated water, active water, etc. This is a promising technology for disinfection and disease control. It is already used successfully in many industries. In horticulture, the main application of electrolysed water is as a ‘biocide’, meaning ‘life-killing’ agent. It is used to break down the slimy build-up in hydroponic lines that often contains bacteria, fungal spores and other microbes. It is also used successfully for disinfection of seeds, flowers, fruits, vegetables, equipment and packing materials and may be used for disease control in greenhouses. Although in the market exist devices for anodic oxidation of water, a university from Latvia has developed his own water activation unit for application in agriculture. The aim was to improve construction of the device and its exploitation characteristics. The university is offering commercial agreement with technical assistance to agricultural equipment manufacturer companies.

Advantages and innovations

The device uses a regular 220V single-phase electricity fourfold increasing the voltage and rectifying the current. The obtained high voltage direct current electrolyser is used for the activation of sprinkling water. The electrolyser effectively purifies, activates and separates crude/unpurified water in the fraction of anions (lifeless water) and in the fraction of cations (live water) as well as simultaneously in electro-coagulation process separates the sediments. The sediments may be used as plant fertilizers. In experiments in greenhouses the application of the activated water in spraying/watering positively influences the productivity of plants.

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.
