Nordlaks is a Norwegian fully integrated company that produces, processes, and sells Atlantic salmon and rainbow trout worldwide. It has just lately completed the constructing of a model new smolt facility for fish as much as 1 pound at Innhavet in Hamarøy municipality. This RAS (recirculating aquaculture system) fish farm is the most important of its type in Norway, with a special concentrate on smolt welfare. The land-based facility has state-of-the-art tools for optimal biosecurity and sustainability. At the center of the RAS process, all recirculation pumps had been equipped by Sulzer.
PROJECT DATA
Fifty AHLSTAR and BE recirculation pumps (continuous duty) in water remedy loops. The dry-installed single-stage overhung pumps are outfitted with semi-open impellers and single mechanical seals.
Five VUPX-0402 (602,312 gallons per hour at 10 toes of head) submersible propeller pumps (intermittent duty) for the emptying of fish tanks.
THE CHALLENGE
The Innhavet RAS plant has thirty-four fish tanks of different capacities (92,000 to 264,000 gallons) in 5 separate main sections. Each section is unbiased from the others and includes its personal complete water therapy system in a semi-closed loop (98 % recirculation plus 2 p.c make-up water). The brackish water from the fish tanks first flows by gravity to a rotating drum filter for the removing of the main suspended solid particles. It then falls into an MBBR (moving bed biofilm reactor) for TAN (total ammonium nitrogen) discount. After passing via a countercurrent degasser for the stripping of nitrogen and carbon dioxide, the handled water is lastly pumped to some head tanks, prior to oxygenation and return to the fish tanks.
In every fish tank, the water is totally renewed each half an hour. The well-being of the smolts is extremely depending on a relentless circulate of water through the facility. The reliability of the recirculation pumps is, therefore, of paramount importance.
High overall vitality efficiency of the RAS plant means a greater environmental footprint and decreased working costs. Consequently, the primary components of the water remedy loops should have top-class efficiencies, significantly the recirculation pumps.
THE SOLUTION
As a long-term provider of apparatus (pumps and turbines) to different Nordlaks crops, Sulzer was concerned at an early stage of the new venture. In collaboration with the Momek Group, a large industrial service supplier in Scandinavia, the pumps had been carefully selected, not solely to fulfil the necessities through the warranty interval, however to run optimally and economically throughout the whole lifetime of the site. For the recirculation of the brackish water, fifty AHLSTAR and BE process pumps in duplex materials have now been put in and are operating continuously. In addition, five VUPX submersible propeller pumps are used on intermittent responsibility when the fish tanks are emptied during the switch of smolts.

CUSTOMER BENEFIT
By choosing to work with a trusted partner, the shopper made sure to get quick and everlasting technical support, along with the most effective products. The recirculation pumps have the following main advantages:
Extremely high hydraulic efficiencies that by far exceed the strictest power laws for water pumps. This means large power financial savings over time and smaller complete cost of ownership, duty factors close to BEP (best efficiency points), low rotation speeds, and inflexible baseplates grouted in concrete. The pump units are working easily with minimized vibration levels. Superior-grade materials is used for all wetted components. For the choice of pump material involved with brackish water, the long-term perspective favored duplex chrome steel quite than 316SS. Duplex steels have higher design energy than austenitic stainless steels, in addition to greater corrosion, abrasion, and pitting resistance. In the tip, maintenance prices and the risk of downtime are decreased.
Sulzer is a acknowledged supplier in the fish farm market, with progressive and proven pumping, mixing, and aeration solutions, and offers highly energy-efficient merchandise with low life-cycle prices and the smallest possible environmental footprint. As a material specialist in a broad range of contemporary water, brackish water, seawater, and brine functions, we will supply pumps in forged iron, 316 stainless-steel, duplex, super duplex, SMO, and so on. .
