Aquaculture oxygen:Oxygen is vital in all aquaculture and this has led focus of associated individuals and managers.The amount of oxygen has a direct impact on: |
1. Reduce the stress of aquatic animal |
1-oxygen tank:
It is one of the oldest method which is used less in aquaculture complexes due to high consumption of Oxygen in these sections.
Advantages:
- No need for electricity
- No need for repairs
- High purity
- No pressure drop
- Continuous operation
- Low capital cost
Disadvantages:
- Need to change daily or weekly
- High cost for charging
- High pressure and associated hazards
- Uncertainty of having full or empty tank
- Required space of 3 square meters
- Replacement of valves
- Required periodic tests
2-Oxygen tank:
Liquid oxygen tanks are world’s modern tanks that operate without the need of power and operator.
Advantages:
- No need for repairs
- No need for periodic service
- Long operating life
- No sound pollution
- No need for electricity
- Low pressure and no associated hazard
- Continuous operation
- No indoor storage required
- No need to set up
Disadvantages:
- Requires monthly charge
- Low passive mode
- Capital cost less than oxygen generator and more than oxygen tank
- Required space of 4 square meters
3-Oxygen genenator:
A high-performance equipment that separate oxygen from the air using zeolite.
Advantages:
• No need to charge
• No need to be replaced
• Low pressure and low associated hazards
• No need to carry
• Guaranteed performance up to 10 years
Disadvantages:
• Low purity in high utilization
• Pressure drop
• Expensive and long-term repairs
• Requires electricity
• Requires operator
• Requires maintenance room
• High capital cost compared to oxygen tanks and vessels
• Need for continuous service
•Noise pollution
• Replacement of zeolite in the long run
• Required space of 4 square meters
TECHNICAL INFORMATION
The aquaculture liquid oxygen tank is a static device that works without the need for electricity and the operator.
These tanks are installed on a foundation in aquaculture complexes and using oxygen carriers, the oxygen fluid is charged in the tank. By opening the valve, the liquid oxygen with the pressure set in the pipeline flows towards the cones and then transmits to the consumer segments.
The only activity required at this time is to check the liquid level gauge weekly, which indicates the full percentage of liquid oxygen in the tank. If this gauge is between 20% and 30%, the next charge must be ordered. The purity of oxygen in these conditions will be constant and due to the pressure regulator, the pressure drop does not occur even at the highest level of consumption.
Manual and automatic settings are easy to do in these tanks
Some important points
Where do we get oxygen ?
There are more than 120 planets of oxygen production in Iran that can supply the oxygen needed for aquaculture. In some small cities, there may not be these liquid oxygen production plants, but this is not worrying. Liquid oxygen carrying vehicles are active throughout Iran and carry oxygen to the most remote parts of Iran.
The price per kilo of liquid oxygen?
Every kilogram of liquid oxygen in Iran is priced at an average of 600 tomans in metropolitan areas and 800 tomans in distant destinations. It should be noted that this amount is based on the cost of discharge at the site and Shipping charge is not included.
How much space is needed?
Contrary to some imaginations, the space required for an aquaculture tank is about 70 meters, the tank area is about 4 x 4 meters, with a diameter of 2.5 meters, which is needed for the reservoir, and the rest for access around the reservoir. This Space for a tank with a capacity of 20 tons of oxygen.
What should be the location of the installation?
The location of the tank should be at the point where the carriage of the carriage is provided and the 1 hour stop of the carriage in that area does not obstruct the route. The location of the reservoir should preferably not be the location of oil and fuel (a distance of 2 meters is sufficient)
