I. Core Functions (Most Commonly Used in Aerobic Fermentation Tanks)

1. Supply oxygen for the respiration of aerobic microorganisms and accelerate the decomposition of organic matter

   Oxygen is an essential substrate for the respiration of aerobic bacteria. Sufficient dissolved oxygen enables beneficial bacteria such as Bacillus and Actinomycetes to multiply rapidly and thoroughly decompose proteins, fats and carbohydrates in manure, oilseed cake fertilizer, kitchen waste and organic wastewater.

   The fermentation cycle is greatly shortened.

   Organic matter can be decomposed more completely with a higher degree of maturity.
2. Eliminate malodor and inhibit anaerobic putrefaction

   Hydrogen sulfide (rotten egg odor), ammonia gas and volatile organic acids are generated inside the tank under oxygen-deficient conditions.

   Continuous oxygen supplementation restrains the reproduction of anaerobic bacteria, preventing blackening, malodor and sourness so as to achieve odor-free fermentation.
3. Kill insect eggs and harmful miscellaneous bacteria

   Aerobic microorganisms generate heat through metabolism, and a high-oxygen environment facilitates the maintenance of high temperatures ranging from 55 to 70°C. The combined effect of high temperature and aerobic conditions kills insect eggs, pathogenic bacteria and putrefactive bacteria, improving the safety of fermented materials (especially critical for water-based fertilizer and liquid organic fertilizer).
4. Raise the upper limit of dissolved oxygen and tackle oxygen supply challenges in deep-water or high-concentration fermentation

   Air delivered by conventional blowers results in low saturated dissolved oxygen in water.

   Pure oxygen injection can substantially increase dissolved oxygen in water, which is applicable to the following scenarios:

   Fermentation liquid with high concentration and high COD value;

   Deep fermentation tanks where air can hardly reach the bottom layer;

   Conventional aeration tends to cause oxygen-deficient dead zones at the bottom, while pure oxygen from oxygen generators boasts stronger permeability.
5. Improve the quality of fermented products

   Sufficient aerobic fermentation of water-based fertilizer and liquid organic fertilizer can:

   Reduce harmful substances;

   Produce more small-molecule organic acids and amino acids that are easier for crops to absorb;

   Avoid root burn caused by alcohol and excessive toxins generated during anaerobic fermentation.
