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 accomplished the building of a brand new smolt facility for fish up to 1 pound at Innhavet in Hamarøy municipality. This RAS (recirculating aquaculture system) fish farm is the biggest of its type in Norway, with a particular concentrate on smolt welfare. The land-based facility has state-of-the-art equipment for optimum biosecurity and sustainability. At the guts of the RAS process, all recirculation pumps had been equipped by Sulzer.
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 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 section is independent from the others and contains its personal complete water treatment system in a semi-closed loop (98 p.c recirculation plus 2 p.c make-up water). ตัววัดแรงดันน้ำมัน from the fish tanks first flows by gravity to a rotating drum filter for the removal of the main suspended strong particles. It then falls into an MBBR (moving bed biofilm reactor) for TAN (total ammonium nitrogen) reduction. After passing via 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 totally renewed every half an hour. The well-being of the smolts is extremely dependent on a continuing flow of water through the ability. pressure gauge 4 นิ้ว ราคา of the recirculation pumps is, subsequently, of paramount significance.
High total energy efficiency of the RAS plant means a better environmental footprint and reduced operating costs. Consequently, the principle parts of the water therapy loops will need to have top-class efficiencies, significantly the recirculation pumps.
As a long-term provider of equipment (pumps and turbines) to other Nordlaks vegetation, Sulzer was concerned at an early stage of the new challenge. In collaboration with the Momek Group, a big industrial service provider in Scandinavia, the pumps were rigorously selected, not only to fulfil the necessities during the warranty interval, but to run optimally and economically during the whole lifetime of the location. For the recirculation of the brackish water, fifty AHLSTAR and BE course of pumps in duplex material have now been put in and are working constantly. In addition, five VUPX submersible propeller pumps are used on intermittent duty when the fish tanks are emptied during the switch of smolts.

By choosing to work with a trusted companion, the shopper made sure to get quick and permanent technical assist, along with the best merchandise. The recirculation pumps have the next major advantages:
Extremely excessive hydraulic efficiencies that by far exceed the strictest energy rules for water pumps. This means large energy financial savings over time and smaller whole cost of possession, duty 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 material in contact with brackish water, the long-term perspective favored duplex stainless-steel quite than 316SS. Duplex steels have higher design energy than austenitic stainless steels, in addition to higher corrosion, abrasion, and pitting resistance. In the end, upkeep costs and the risk of downtime are reduced.
Sulzer is a recognized supplier in the fish farm market, with revolutionary and proven pumping, mixing, and aeration solutions, and supplies extremely energy-efficient merchandise with low life-cycle costs and the smallest possible environmental footprint. As a fabric specialist in a broad range of fresh water, brackish water, seawater, and brine functions, we will provide pumps in forged iron, 316 stainless steel, duplex, tremendous duplex, SMO, and so forth. .
