At the Heart of the Largest Smolt Facility in Norway

Nordlaks is a Norwegian fully built-in company that produces, processes, and sells Atlantic salmon and rainbow trout worldwide. It has lately completed the building of a brand 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 focus on smolt welfare. ตัววัดแรงดันน้ำ -based facility has state-of-the-art tools for optimal biosecurity and sustainability. At the guts of the RAS course of, all recirculation pumps were provided by Sulzer.
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 feet of head) submersible propeller pumps (intermittent duty) for the emptying of fish tanks.
The Innhavet RAS plant has thirty-four fish tanks of various capacities (92,000 to 264,000 gallons) in five separate major sections. Each part is impartial from the others and includes its personal complete water treatment system in a semi-closed loop (98 p.c 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 elimination of the primary suspended stable particles. It then falls into an MBBR (moving bed 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 each fish tank, the water is totally renewed every half an hour. The well-being of the smolts is extremely dependent on a continuing flow of water through the facility. ราคาเกจวัดแรงดัน of the recirculation pumps is, due to this fact, of paramount significance.
High total power efficiency of the RAS plant means a better environmental footprint and decreased working prices. Consequently, the principle elements of the water treatment loops will need to have top-class efficiencies, significantly the recirculation pumps.
As a long-term provider of apparatus (pumps and turbines) to other Nordlaks plants, Sulzer was involved at an early stage of the new project. In collaboration with the Momek Group, a big industrial service provider in Scandinavia, the pumps have been carefully selected, not only to fulfil the requirements 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 installed and are working continuously. In addition, five VUPX submersible propeller pumps are used on intermittent duty when the fish tanks are emptied in the course of the transfer of smolts.

By selecting to work with a trusted associate, the client made positive to get quick and permanent technical help, in addition to the most effective products. The recirculation pumps have the following major benefits:
Extremely excessive hydraulic efficiencies that by far exceed the strictest power laws for water pumps. This means large power savings over time and smaller complete value of ownership, duty factors near BEP (best effectivity points), low rotation speeds, and inflexible baseplates grouted in concrete. The pump models are working smoothly with minimized vibration ranges. Superior-grade materials is used for all wetted parts. For the selection of pump materials in touch with brackish water, the long-term perspective favored duplex stainless-steel somewhat than 316SS. Duplex steels have better design strength than austenitic stainless steels, in addition to larger corrosion, abrasion, and pitting resistance. In the top, upkeep costs and the danger of downtime are lowered.
Sulzer is a recognized supplier within the fish farm market, with revolutionary and proven pumping, mixing, and aeration options, and provides extremely energy-efficient products with low life-cycle costs and the smallest potential environmental footprint. As a cloth specialist in a variety of contemporary water, brackish water, seawater, and brine purposes, we will provide pumps in forged iron, 316 chrome steel, duplex, tremendous duplex, SMO, and so forth. .
