How air blowers are used in aquaculture farms
Oxygen is vital to raise and support aquatic life. But oxygen solubility is greatly impacted by the temperature of the water. For example, oxygen solubility at 0° C is about 14.6 ppm, and solubility at 40° C is 6.4 ppm. This makes running an aquaculture farm in the Middle East challenging because of the extreme heat.
Aeration techniques that raise the levels of oxygen saturation throughout a body of water – solve this problem. But they are energy intensive.
Pneumatic conveying or feeding systems
Air blowers support pneumatic conveying systems which are an effective way to disperse powder or feeding pellets of various sizes. Having access to a wide range of blowers suited for different pressures and flows, you are sure to find a perfect fit within our air blower portfolio for whichever type of food you are dealing with.
Bubble curtains
Air blowers can create bubble curtains to protect your aquaculture farm. A bubble curtain is a stream of bubbles around a pen that prevents jellyfish and sea lice from passing through. Our air blowers guarantee a high uptime which is necessary for the bubble curtain to be effective.
Live fish handling
Air blowers allow you to devise a pressure system for loading and unloading live fish. It’s a gentle and efficient way of transporting live fish. And it minimizes handling time which is better for the welfare of your aquaculture population. Our compact air blower solutions are an ideal fit if you are looking to save space when working in confined spaces such as boats.
Dead fish removal
Air blowers are helpful because they allow you to supply a rapid and constant stream of bubbles inside a special collector at the bottom of a cage which will bring dead fish up and onto your boat. Dead fish can form a health threat to your population and decrease your operational efficiency so it's important that they are removed as soon as possible.
Aeration
Air blowers combine well with diffuser devices to aerate water from the bottom up. The principle of aeration is used to maintain the right oxygen levels as well as provide water circulation, thermoregulation, biological treatment, freeze protection in cold weather conditions and reduce temperature induced stress among the stock.
The right air blower selection
We recommend investing in a rotary lobe air blower or a centrifugal air blower. For each use of the air blowers within the fish farming it calls for the most efficient & reliable blower to operate. Typically rotary lobe air blowers are commonly used pressure up to 0.4 bar and below and flows below 500m3/h.
Why air blowers with variable speed drive technology are a great choice
Compressed air applications within the aquaculture industry require a high uptime with variable air flow requirements. Blowers equipped with variable speed drives can help meet such requirements ensuring the pressure is maintained by varying the air flow.
Variable speed drives can vary the speed of a normally fixed-speed motor to perfectly match the air flow and air pressure demands of your application at any given time.
Installing the right air blower with VSD+ technology into your aeration systems will give you air purity levels of above 95% and save up to 35% on your energy costs.
