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. It has lately completed the constructing of a model new smolt facility for fish as a lot as 1 pound at Innhavet in Hamarøy municipality. This RAS (recirculating aquaculture system) fish farm is the most important of its kind in Norway, with a particular focus on smolt welfare. The land-based facility has state-of-the-art gear for optimum biosecurity and sustainability. At the center of the RAS course of, all recirculation pumps were provided by Sulzer.
Fifty AHLSTAR and BE recirculation pumps (continuous duty) in water therapy loops. The dry-installed single-stage overhung pumps are geared up 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 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 impartial from the others and consists of its personal full water treatment system in a semi-closed loop (98 percent recirculation plus 2 percent make-up water). The brackish water from the fish tanks first flows by gravity to a rotating drum filter for the removal of the principle 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 finally 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 highly depending on a constant move of water through the ability. The reliability of the recirculation pumps is, subsequently, of paramount importance.
High general power performance of the RAS plant means a better environmental footprint and decreased working prices. Consequently, the main components of the water remedy loops must have top-class efficiencies, notably the recirculation pumps.
As a long-term supplier of apparatus (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 large industrial service supplier in Scandinavia, the pumps have been rigorously chosen, not solely to fulfil the requirements 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 course of pumps in duplex materials have now been installed and are working continuously. In addition, 5 VUPX submersible propeller pumps are used on intermittent obligation when the fish tanks are emptied in the course of the switch of smolts.

By selecting to work with a trusted companion, the client made positive to get fast and everlasting technical assist, in addition to the best products. The recirculation pumps have the following major advantages:
Extremely high hydraulic efficiencies that by far exceed the strictest energy laws for water pumps. This means huge energy financial savings over time and smaller complete cost of ownership, obligation factors near BEP (best efficiency points), low rotation speeds, and rigid baseplates grouted in concrete. The pump items are working easily with minimized vibration levels. Superior-grade material is used for all wetted parts. For the choice of pump materials in touch 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 tip, maintenance costs and the chance of downtime are reduced.
เครื่องวัดแรงดันเกจที่นิยมใช้ is a recognized provider within the fish farm market, with progressive and confirmed pumping, mixing, and aeration solutions, and supplies extremely energy-efficient products with low life-cycle prices and the smallest potential environmental footprint. As a cloth specialist in a extensive range of recent water, brackish water, seawater, and brine applications, we are in a position to supply pumps in cast iron, 316 stainless-steel, duplex, tremendous duplex, SMO, etc. .
