Auto Draft

Nordlaks is a Norwegian absolutely built-in firm that produces, processes, and sells Atlantic salmon and rainbow trout worldwide. It has recently completed the constructing of a 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 type in Norway, with a particular concentrate on smolt welfare. The land-based facility has state-of-the-art gear for optimum biosecurity and sustainability. At the guts of the RAS process, 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 equipped 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 5 separate main sections. Each section is unbiased from the others and consists of its personal full water therapy 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 main suspended solid particles. It then falls into an MBBR (moving mattress biofilm reactor) for TAN (total ammonium nitrogen) discount. After passing by way of 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 each half an hour. The well-being of the smolts is very dependent on a relentless circulate of water by way of the facility. The reliability of the recirculation pumps is, due to this fact, of paramount significance.
High total energy performance of the RAS plant means a greater environmental footprint and lowered operating costs. Consequently, the principle elements of the water remedy loops should have top-class efficiencies, particularly the recirculation pumps.
THE SOLUTION
As a long-term supplier of apparatus (pumps and turbines) to different Nordlaks crops, Sulzer was involved at an early stage of the new venture. In collaboration with the Momek Group, a big industrial service supplier in Scandinavia, the pumps had been fastidiously chosen, not only to fulfil the requirements through the warranty period, however to run optimally and economically throughout the whole lifetime of the positioning. For pressure gauge ลม of the brackish water, fifty AHLSTAR and BE course of pumps in duplex materials have now been installed and are operating repeatedly. In addition, five VUPX submersible propeller pumps are used on intermittent obligation when the fish tanks are emptied in the course of the switch of smolts.

CUSTOMER BENEFIT
By choosing to work with a trusted associate, the consumer made sure to get fast and everlasting technical support, in addition to the most effective products. The recirculation pumps have the next main advantages:
Extremely high hydraulic efficiencies that by far exceed the strictest power regulations for water pumps. This means big power financial savings over time and smaller whole value of ownership, duty points close to BEP (best effectivity points), low rotation speeds, and rigid baseplates grouted in concrete. The pump units are working easily with minimized vibration levels. Superior-grade material is used for all wetted parts. For เกจวัดแรงดันน้ําไทวัสดุ of pump material in contact with brackish water, the long-term perspective favored duplex chrome steel rather than 316SS. Duplex steels have higher design power than austenitic stainless steels, in addition to greater corrosion, abrasion, and pitting resistance. In the top, upkeep costs and the chance of downtime are lowered.
Sulzer is a acknowledged supplier within the fish farm market, with revolutionary and confirmed pumping, mixing, and aeration solutions, and offers extremely energy-efficient products with low life-cycle costs and the smallest attainable environmental footprint. As a cloth specialist in a variety of recent water, brackish water, seawater, and brine applications, we are able to supply pumps in forged iron, 316 stainless-steel, duplex, tremendous duplex, SMO, etc. .
