Clean and healthy water in aquaculture facilities requires the careful use of disinfection equipment, filters, flushing, de-gassing and circulation. This process requires a reliable and energy efficient pumping system.
Fish farms are a crowded place with no time to stop the pump to take it apart for the purpose of re-greasing. Pumps for fish farms require a longer duty cycle.
Fish Farm Pump Systems
Fish farms are becoming more frequent as global demand increases, as well as because the oceans are overfished. Pumps are utilized to move seawater and recirculate the water within these vast fish farms, to stop stagnation.
Aquaculture is a major expense for farms. Pumping represents a large proportion of all energy consumed. By selecting the correct pumps, the operators are able to substantially reduce their energy expenses.
To determine the needed pump capacity, divide fish tank size by preferred turnover rate (turnover every hour) to find the flow rate needed. Choose a pump that has the capacity to match. Fisheries can be very busy and there’s not much time for long-running service calls if pumps stop working – especially in the case of live fish.
Aquaculture Pump Efficiency
Pumps are critical in aquaculture, allowing oxygenation distribution of water and transfer of nutrients. Yet, the amount energy they consume is one of the highest operating costs.
In order to increase the effectiveness of the system, ensure the pump you choose to use is properly sized for the needs of your system. Calculate the desired tank turnover amount and then divide that by the capacity of your bom cong nghiep for the amount of grams per hour (or L/hour) you require.
The duration of pumping and the power consumption could be cut by reducing the pump’s velocity to a lesser flow when it is needed. Danfoss can provide variable-speed drives which permit the motor’s speed to be adjusted electrically. This allows you to monitor the system’s flow accurately as well as save money on “fifth energy source”. Reducing operating expenses is the main goal of efficient energy consumption.
Sustainable Pumping Solutions for Fish Farms
Aquaculture is confronted with numerous challenges such as salmon lice, problems with water quality as well as algal growth and waste management. To mitigate these, fisheries depend on high-efficiency and sustainable pumps to disinfect filters, flushes, de-gas, and circulate water.
Danfoss provides a variety of pumps as well as power conversion technology designed for farms with fish that enhance the efficiency of your pump by reducing power consumption. For example, by applying Danfoss’s system for controlling the speed of pumps it is possible to reduce the amount of fuel used in the recirculation of water by at least 50%.
Fishing is a bustling place, where everything can happen within the span of the eye. Since the lives of livestock depend on the constant stream of water, there are no excuses for wasting time. Therefore, they require sturdy, reliable pumps which do not require oil or lubrication. One solution is to use an air-injection pump.
Maintenance of the Aquaculture Pump
The cost of energy is the second largest operational expense in the majority of Florida aquaculture production system. Improving pumping in aquaculture is a way of reducing this cost. Proper system size, installation and selection of pumps can increase quality and reliability.
Pumps should be engineered to work at the highest efficiency (BEP). Cavitation can occur when pumps are not operating at the best efficiency point (BEP). It may result in high cost of maintenance as well as operating costs.
It is essential to consider the topography as it could impact the water’s stability and drainage, along with erosion risk. Also, it affects conditions of the lake (temperature, salinity, pH, and dissolving oxygen) required for specific types of fish to thrive. In the event that a pump breaks having another one available will reduce downtime.
Innovative Pump Technologies for Aquaculture
For aquaculture, superior the quality of water is vital to long-term sustainability of fish production. However, increasing fish population and the resulting crowded environment can lead to problems with health of water as well as stress and disease.
Constant Flow Technology helps maintain regular flow rates despite changing circumstances. This can be particularly helpful in RAS systems that have media filters, which prevents out waste that could block the system as well as to keep that oxygen gas flows are at their optimal level.
DESMI has a brand new line of low-pressure, high-flow pumps designed for RAS as well as flow-through in the land. They’re much simpler to maintain and offer more energy-efficient performance over larger capacities than massive propeller pumps. They are also compatible with PLC menus designed specifically for the industry. Precision load measurement solutions are vital for applications in aquaculture.
