ProMinent in Norway Opens Doors - With Global Support!
A recirculating aquaculture systems supplier has leaned on ProMinent Norge’s knowledge of pH adjustment for a new facility in Japan.
Effective pH Regulation for Global Fish Farming Facilities
A recirculating aquaculture systems supplier has leaned on ProMinent Norge’s knowledge of pH adjustment for a new facility in Japan.
Pure Salmon Technology AS, a fish farm equipment manufacturing company that has been around since 2010, builds RAS (recirculating aquatic systems) for salmon farming in Norway, Japan, USA, France and Brunei - with advanced plans for the Middle East.
Pure Salmon needed to find a reliable solution partner for pH adjustment in land-based ponds worldwide and had heard about PoMinent’s previous success with water treatment solutions for RAS.
With the first joint project for a newly established facility in Tsu City, Japan.
Key data
- Reliable pH regulation for land-based fish farming systems
- Use of chemical dosing systems for pH correction
- Focus on safety when handling chemicals (e.g., sodium hydroxide)
- The solution needed to be adaptable to various climate conditions and standards globally
Safe pH Dosing for Tsu, Japan
Geir Klingberg, product and sales engineer for ProMinent Norway said: "The first thing we had to do was to contact our colleagues at ProMinent Japan, to ensure the directives, pipe standards, safety regulations, and electricity supply of the country were taken into account. Once we had all that in place, including the European CE standard being sufficient, and, interestingly discovering that the electricity supply differs between northern and southern Japan, we could start construction."
The correct pH of the water is an important parameter for fish to grow well. The adjustment is usually done by dosing sodium hydroxide, also called lye. The project for Tsu consists of 52 safety dosing cabinets which feature solenoid-driven dosing pumps gamma /X and gamma /XL.
Geir said: "For the customer, there are many advantages to buying our safety dosing cabinets instead of loose components. It is a 'plug & play' unit that is CE marked according to the Machinery Directive and the customer only needs to add power on-site. Delivery of these cabinets will take place during spring 2025 to Tsu. This means that the last step for us, in this particular project, will be to hand over to our colleagues at ProMinent in Japan."
In early June 2024, Takahiro Omoda and Hiroyasu Nihommatsu from ProMinent Japan visited ProMinent's Scandinavian headquarters in Gothenburg, where the safety cabinets are produced, for a joint review and inspection.
Hiroyasu, Technical Manager at ProMinent Japan, said: "It is an exciting project that provides experience and references that can help us enter this market as well. "That is also one of the strengths of ProMinent, we are present worldwide with our products and expertise.The synergy effect for customers is enormous. We see great potential for RAS in Japan."
Global Success with Safe pH Dosing
Geir added: "To date, we at ProMinent in Norway have sold around 80 safety dosing cabinets for pH adjustment in RAS, which is very exciting. Not only to Pure Salmon Technology but also to other players in the market. Most with delivery to various plants here in Norway. Aquaculture system suppliers are often based in Norway but supply RAS pools across Europe, Asia, and North America.
Hiroyasu added: "ProMinent in Norway opened the door for the group, it means that we will be able to offer 'one-stop solutions' to end customers in the same way they do."In this case, we’ll take over and support the customer on site in Tsu if they want help with installation, service, or spare parts management."
These 52 cabinets are for pH adjustment only, but ProMinent's solutions and breadth of equipment mean we can be a partner for all water treatment and chemical management in RAS.
Geir added: "If we look at water disinfection, we have both UV and Ozone systems, which are chemical-free, gentle, and effective methods. For dewatering sludge, we have our Spectra progressive cavity pump. This means both mechanical and biological treatment. Storage tanks up to 70 cubic meters, dosing systems for flocculants, measuring instruments, and sensors for most conceivable parameters and needs are available in our range. I think I can go on and on, there's nothing we can't support the customer within terms of water treatment or dosing, only the customer or the imagination sets the limits."
ProMinent looks forward to working on more global RAS projects and is proud to be part of ensuring that we can continue to serve fish on our tables.
