Compressed air is purified through the air dryer and filters to a certain level for main plant to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The plant produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure.
With a cabinet for small capacity or container for big capacity, all the parts can be involved in, and removable with a vehicle.

Prevention and cure of the "bottom dead" disease of white shrimp in South America
After nearly two years of observation and summary, the "bottom dead" of South American white shrimp mainly has the following characteristics: (1) "Dead bottom" usually occurs in the middle and later stages of breeding, when the weather is hot and changing. (2) "Bottom dead" usually occurs in shrimp ponds with a relatively high culture density, and dead shrimps are relatively large individual shrimps in the pond. (3) There was no shrimp in the entire pond that had reduced or slowed feeding, and there was no sick shrimp floating on the water. Reasons for "bottom dead" (1) There is not enough dissolved oxygen at the bottom of shrimp ponds, and the environment is deteriorating, and a large amount of toxic and harmful substances have been accumulated. (2) The shrimp itself has malnutrition, poor resistance, and difficulty in clam shells. Prevention and control of "bottom dead" (1) Prevention: In the breeding process, improve the environment for the survival of shrimps and increase the amount of dissolved oxygen in the pool. Available black cyclone, oxygen Li Wei, etc. per mu per meter depth of 2.5 to 3.5 kg + 200 to 250 grams of large shrimp poison mixed dry sprinkle. At the same time, it is also necessary to improve the disease resistance of shrimps, which can be used in combination with liver and stomach treasures, detoxification and detoxification spirits, etc., at a ratio of 5-8 g/kg of feed for internal use. (2) Treatment: When P. vannamei has a "bottom dead" phenomenon, it should take active measures to control the condition. For external use: Povidone iodine (containing 1% iodine) 200-250 ml + Baidu Decoction 250-300 ml mixed dilution sprinkling per acre water depth, the next day, with oxygen ribo or detoxification change per acre Each meter of water depth 3.5 kg + water quality optimization of 400 grams mixed with water spilled, 24 hours after the appropriate amount of water, with EM bacteria and other live bacteria 3 g / mu to regulate water quality. Oral administration: Hepatoprotective heme (6 g), Liver and Gastrodia Poison (10 ml), Menning (3 g), Immuno-polysaccharide (10 g), and Vitamin C (5 g) are fed for 5 days.
