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
2. Increase aquatic growth up to 2.5 in similar conditions
3. Reduced intake water up to 33% in similar conditions
4. Reduction of  fatalities
5. Reduction of  disease
6. Increase of growth

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)

Select the tank

In choosing oxygen reservoir, the following important points should be considered:

– Development plan: Due to 40 years of liquid oxygen storage, it is better to consider at least the development plan for fish breeding for up to 3 years – the position of aquaculture complex- Biomass Aquaculture Plant-Installation Place: In the aquaculture facility, the installation site should be checked whether there is a possibility to install the oxygen reservoir in the area under these conditions! Is the position suitable for the cranes to fit! And … Selecting the oxygen tank according to the aquaculture complex, based on the type of fish or shrimp, the aquatic weight, the normal growth, the feeding rate, the type of water entering. Exactly by the experts of the company, Zhemchaar, the sky is done, but for an estimation An example is the following table. The important thing about oxygen is that if you use water from a river or a well, this water contains oxygen, and oxygen should be used to increase this amount.

Liquid Oxygen Tank (1 ton).

Each meal is about 70kg.

Second Edition: sets that use up to 5 capsules per day.

Third:

Sets that use a high-oxygen-type oxygenator.

(1 ton of oxygen is suitable for these reservoir centers)

Financial Estimate – Justifying Plan:
The tanks declared in the table above are in terms of oxygen capacity, for example, a tank (4 tons) containing 4,000 kg of liquid oxygen. The cost per kilo of oxygen with the total cost of transportation is from (6,000 to 8,000) Rials Given the distances or proximity to the provincial capital, this price will change. The initial charging price of a tank is as follows.
28.000 (Rials) = 7.000 (Rials) * 4000 (Kilogram)
If we want to compare this reservoir with a 40-liter oxygen capsule, each 40-liter capsule with a pressure of 120 times is equivalent to 7 kilos of liquid oxygen, which costs an average of 150,000 (rials) per capsule. For a hospital With a daily consumption of 20 capsules, the estimate is calculated without taking into account the loading, discharging and replacement of the capsule for one month, as follows:
90,000,000 (Rials) = 150,000 (Rials) * 20 (capsule number) * 30 (days)
Which is about three times the consumption of liquid oxygen tank.
