To keep water in aquaculture facilities, it is important to filter, disinfect, flush, de-gass and circulate. This process requires a reliable and energy efficient pumping system.
Fisheries are busy places with limited time for a pump to take it apart for re-greasing. Pumps that are used in fish farming need to be able to handle their own high demand.
Fish Farm Pump Systems
Fish farms are becoming increasingly frequent as global need grows and oceans have been overfished. Pumps can be used for moving seawater around and to recirculate the water inside these massive fish farms, to stop stagnation.
It is one of the primary expenses associated with farming in aquaculture, with pumping representing a significant portion of the total energy consumption. When choosing the right dimension of the pump, farmers can dramatically reduce the energy cost.
To determine the needed pump capacity, simply divide the fish tank size by desired rate of turnover (turnover in an hour) in order to calculate the rate of flow required. Select a pump that has the same capacity. Fisheries can be very busy therefore there’s no room for lengthy service calls when pumps fail to work – and especially in the case of live fish.
Aquaculture Pump Efficiency
In aquaculture, may bom cuu hoa are essential for water transfer as well as distribution of nutrients and oxygenation. But, the amount of energy they use is one of the highest operating cost.
The most effective way to increase efficiency in your system is to ensure your pump is sized correctly to the application you are using it for. Estimate the desired tank turn-over rate and then divide it by your pump’s capacity to figure out the number of gallon per hour (or L/hour) are required.
Duration of the pump and energy consumption can be decreased by slowing the speed of the pump at times when less than the full flow is required. Danfoss has variable speed drive that permit you to change the pump motor speed electrically. It means you are able to monitor the system’s flow accurately as well as save money on “fifth gasoline”. Reducing operating expenses is an issue of efficiency in energy use.
Sustainable Pumping Solutions for Fish Farms
The aquaculture industry faces many issues: lice in salmon, the quality of water, algae problems, as well as waste management. To mitigate these, fisheries rely on highly efficient and eco-friendly pumps that can disinfect and flush, filter as well as de-gas and circulate water.
Danfoss provides a variety of pumps to fish farms that can reduce the energy use and increase the efficiency of pumping. As an example, if you use the Danfoss control of speed it is possible to reduce fuel usage in the recirculation of water by up to 50 percent.
Fisheries are bustling places, where many things happen in the blink of an eye. When the lives of livestock depend on a continuous stream of water, there isn’t much time left. The need for pumps that can be maintained easily and require no lubrication. A pump that uses air is one solution.
Maintenance of Aquaculture Pumps
In Florida it is the case that energy expenses are at the bottom of the list for operating expenses. One way to lower the costs of these is by enhancing pumps used for aquaculture. Correct system size and placement of pumps will also improve performance, reliability and longevity.
The pump must be constructed to operate at the highest effectiveness (BEP). It is possible for cavitation to occur if pumps are not operated at the highest efficiency level (BEP). This can result in costly cost of maintenance as well as operating costs.
It is crucial to assess the topography that can affect the stability of water and drainage, as well as erosion risk. Additionally, it influences the parameters that determine water quality (temperatures as well as salinity, pH and dissolved oxygen and many others.) which are necessary for specific fish species to thrive. The addition of a second pump to the system available and connected to the system reduces downtime in the event of the system failing.
Innovative Pump Technologies for Aquaculture
It is essential to have high-quality water in order in order to guarantee sustainable production. However, increasing fish population and conditions of overcrowding can lead to poor water quality, stress and disease.
Constant Flow Technology helps maintain steady flow rates even in fluctuating circumstances. This can be particularly helpful in RAS systems with media filters in order to prevent the debris from getting into the system and ensure oxygen gas supply at optimal levels.
DESMI has developed a range of high-flow and low-pressure pumps that are suitable for RAS applications and for flow-through on land. They are easier to maintain and boast better energy efficiency over larger capacities than big propeller pumps. With an aquaculture-specific drive, they also support PLC control menus that are specific to the demands of this highly competitive industry. Accurate load measurement is essential for aquaculture operations.
