At the Heart of the Largest Smolt Facility in Norway

Nordlaks is a Norwegian totally built-in company that produces, processes, and sells Atlantic salmon and rainbow trout worldwide. It has recently completed the building of a new smolt facility for fish as much as 1 pound at Innhavet in Hamarøy municipality. This RAS (recirculating aquaculture system) fish farm is the largest of its kind in Norway, with a particular focus on smolt welfare. The land-based facility has state-of-the-art equipment for optimal biosecurity and sustainability. At the guts of the RAS course of, all recirculation pumps had been equipped by Sulzer.
PROJECT DATA
Fifty AHLSTAR and BE recirculation pumps (continuous duty) in water therapy 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 ft 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 five separate main sections. Each part is unbiased from the others and consists of its personal full water remedy system in a semi-closed loop (98 percent recirculation plus 2 % make-up water). The brackish water from the fish tanks first flows by gravity to a rotating drum filter for the elimination of the main suspended solid particles. It then falls into an MBBR (moving mattress biofilm reactor) for TAN (total ammonium nitrogen) discount. After passing through a countercurrent degasser for the stripping of nitrogen and carbon dioxide, the handled water is finally pumped to some head tanks, previous to oxygenation and return to the fish tanks.
In every fish tank, the water is absolutely renewed each half an hour. The well-being of the smolts is extremely dependent on a relentless circulate of water via the ability. The reliability of the recirculation pumps is, subsequently, of paramount importance.
High total vitality efficiency of the RAS plant means a greater environmental footprint and decreased working prices. Consequently, the primary parts of the water treatment loops should have top-class efficiencies, significantly the recirculation pumps.
THE SOLUTION
As a long-term supplier of kit (pumps and turbines) to other Nordlaks vegetation, Sulzer was involved at an early stage of the brand new project. In collaboration with the Momek Group, a large industrial service supplier in Scandinavia, the pumps were fastidiously selected, not only to fulfil the necessities through the warranty period, however to run optimally and economically throughout the entire lifetime of the positioning. For the recirculation of the brackish water, fifty AHLSTAR and BE course of pumps in duplex materials have now been put in and are operating continuously. In addition, 5 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 positive to get quick and everlasting technical assist, in addition to the most effective merchandise. เกจวัดแรงดันnuovafima have the next main advantages:
Extremely high hydraulic efficiencies that by far exceed the strictest energy laws for water pumps. This means big energy savings over time and smaller whole cost of ownership, obligation points close to BEP (best effectivity points), low rotation speeds, and rigid baseplates grouted in concrete. The pump models are working easily with minimized vibration levels. Superior-grade material is used for all wetted components. For the selection of pump materials involved with brackish water, the long-term perspective favored duplex chrome steel quite than 316SS. Duplex steels have better design strength than austenitic stainless steels, as properly as greater corrosion, abrasion, and pitting resistance. In the end, maintenance costs and the risk of downtime are decreased.
Sulzer is a recognized supplier in the fish farm market, with progressive and proven pumping, mixing, and aeration options, and offers highly energy-efficient products with low life-cycle prices and the smallest possible environmental footprint. As a cloth specialist in a variety of contemporary water, brackish water, seawater, and brine functions, we can supply pumps in forged iron, 316 chrome steel, duplex, tremendous duplex, SMO, and so forth. .
