Kaldnes™ RAS

Krüger Kaldnes has recently signed an agreement with Sundsfjord Smolt for the delivery of a Recirculating Aquaculture System (RAS) for reuse and quality management of process water for land based fish farming - Kaldnes™ - RAS.

The company with its head office in Sandefjord, Norway, does not hide the fact that the aquaculture industry is an important priority area.
"This is yet another proof that more and more fish farmers pay an interest in our eminent solutions", says a satisfied Marius Hægh, sales manager in the aquaculture-department of Krüger Kaldnes. He continues:

"Our RAS-solution is founded on the well-established AnoxKaldnes™ MBBR combined with Hydrotech drumfilters. These versatile technologies are well proven within this market and provide great benefits to our clients".

Along with key knowledge about the industry Krüger Kaldnes is well positioned for further growth for delivering water treatment systems to the aquaculture market.

Flexibility and compactness characterizes the new facility for salmon smolt production. The new treatment facility will be placed in existing buildings, scheduled to be operational in May 2012.

Marine Harvest in Norway has awarded Krüger Kaldnes the contract for construction of a new recycling facility at the hatchery on Dravlaus in Dalsfjord. The recycling plant will be built for the nursery and pre-ongrowing part of the plant and thus completes the recycling facility provided by Krüger Kaldnes in 2010 which was created for the ongrowing part of the fishfarm. The total capacity for the two recycling plants is equivalent to a feeding of more than 5000 kg per day and an annual production of about 5 million smolts. The project includes a turnkey treatment plant where the main process is based on the patented Kaldnes™ MBBR biofilm process. The treatment process also includes Hydrotech drum filters, CO2-removal, instrumentation, pumping equipment, PLC board and a fully operational control system.

"We are very pleased that the Marine Harvest again chose Krüger Kaldnes as a supplier for the construction of its recycling facilities. They are the world's largest breeder of salmon and will build a number of new recycling plants in the future. In cooperation with Marine Harvest, we have developed a completely new and innovative way to process recycling water that is environmentally friendly, energy efficient and extremely compact. The concept will have a major impact for our investment in the fish farming market in Norway and internationally", says Marius Hægh, Sales Manager, Fish Farms / M.Sc.

Krüger Kaldnes in Norway has been awarded the contract for a fish farming project by Marine Harvest in Norway together with the Norwegian company BioDesign. The contract covers the construction of the water treatment part for a new recirculation plant for smolt in Dalsfjord, Norway.

The project comprises a turnkey treatment plant based on the patented AnoxKaldnes® MBBR process. The process package also includes drum filters, CO2 stripping, instrumentation, pump equipment and control panel with PLC.

The plant has been designed with the objective of developing tomorrow's technology for recirculation plants with low energy consumption, extremely compact solutions and environmentally adapted to modern fish farming.

"This treatment concept has been developed in cooperation with Marine Harvest. Marine Harvest is the world's largest producer of farm raised salmon and will construct a series of new recirculation plants in the years to come. We have developed a completely new and innovative method to treat waters in recirculation plants, a method that is green, energy-efficient and extremely compact. This concept will be very important for our investment in the fish farming market in Norway and internationally"says Marius Hægh, Sales manager Fish Farms/M.Sc.

The plant must be handed over in 2009/2010.
