At the Heart of the Largest Smolt Facility in Norway

Nordlaks is a Norwegian fully integrated company that produces, processes, and sells Atlantic salmon and rainbow trout worldwide. ร้านซ่อมเครื่องวัดความดัน has recently 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 largest of its type in Norway, with a particular give attention to smolt welfare. The land-based facility has state-of-the-art gear for optimal biosecurity and sustainability. At the guts of the RAS course of, all recirculation pumps were supplied by Sulzer.
PROJECT DATA
Fifty AHLSTAR and BE recirculation pumps (continuous duty) in water treatment 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 various capacities (92,000 to 264,000 gallons) in five separate major sections. Each section is unbiased from the others and includes its own full water therapy system in a semi-closed loop (98 % 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 principle suspended solid particles. It then falls into an MBBR (moving bed biofilm reactor) for TAN (total ammonium nitrogen) reduction. After passing by way of 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 fully renewed every half an hour. The well-being of the smolts is extremely depending on a relentless circulate of water via the power. The reliability of the recirculation pumps is, therefore, of paramount importance.
High general vitality efficiency of the RAS plant means a better environmental footprint and reduced working prices. Consequently, the main parts of the water treatment loops should have top-class efficiencies, particularly the recirculation pumps.
THE SOLUTION
As a long-term provider of equipment (pumps and turbines) to other Nordlaks vegetation, Sulzer was concerned at an early stage of the model new venture. In collaboration with the Momek Group, a big industrial service provider in Scandinavia, the pumps were rigorously chosen, not solely to fulfil the necessities in the course of the guarantee interval, however to run optimally and economically during the entire lifetime of the positioning. For the recirculation of the brackish water, fifty AHLSTAR and BE process pumps in duplex materials have now been installed and are working repeatedly. In addition, 5 VUPX submersible propeller pumps are used on intermittent responsibility when the fish tanks are emptied through the transfer of smolts.

CUSTOMER BENEFIT
By selecting to work with a trusted associate, the consumer made positive to get fast and permanent technical assist, along with the most effective merchandise. The recirculation pumps have the following major advantages:
Extremely high hydraulic efficiencies that by far exceed the strictest power regulations for water pumps. This means large power financial savings over time and smaller complete value of possession, duty factors close to BEP (best efficiency points), low rotation speeds, and inflexible baseplates grouted in concrete. The pump units are working smoothly with minimized vibration ranges. Superior-grade materials is used for all wetted elements. For the selection of pump materials involved with brackish water, the long-term perspective favored duplex stainless-steel quite than 316SS. Duplex steels have higher design strength than austenitic stainless steels, in addition to higher corrosion, abrasion, and pitting resistance. In the top, upkeep prices and the risk of downtime are decreased.
Sulzer is a recognized supplier within the fish farm market, with revolutionary and confirmed pumping, mixing, and aeration solutions, and offers extremely energy-efficient merchandise with low life-cycle prices and the smallest potential environmental footprint. As a fabric specialist in a broad range of recent water, brackish water, seawater, and brine applications, we are able to supply pumps in cast iron, 316 stainless-steel, duplex, super duplex, SMO, etc. .
