Scope of application:
  • Calcium peroxide releases oxygen slowly in contact with atmospheric moisture and used to generate contaminated soils and lakes.
  • It is used as a slow oxygen release source in agricultural application.
  • It is used in the bleaching and deodorizing.
  • Used as a curing agent in rubber, starch modification, dough conditioner, industrial oxidizer, ingredient in deodorizers, cosmetics and dentifrices and in Agriculture, metallurgy, bioremediation, aquaculture, animal rearing,

In environmental protection::
  1. For treating waste water and remediation of groundwater.
  2. For decontaminating soil.

In aquaculture:
  1. To provide sufficient dissolved oxygen.
  2. To adjust pH value.
  3. To reduce the subaqueous content of ammonium and nitrogen.
  4. To eliminate carbon dioxide and sulfurated hydrogen.
  5. To prevent anaerobe from proliferation and killing nosogenetic bacteria, defecating aqueous body.

In poultry-raising: 
  1. To decontamination of fodder. 
  2. To increase productivity, hens safety and improving their eggs. 

In cattle-breeding: 
  1. For prophylaxis of casein-stone formation in the abomasum and diarrhoea with newborn calves.
  2. For an antimicrobial effect;
  3. For stimulating protective organism strength;
  4. For normalizing activity of the alimentary canal;
  5. For activating digestion work;6. For greater live-stock safety.

In precious metal production:

  1. For leaching precious metals in the formation of cyano complexes (particularly complexes with gold and/or silver) from ores, ore concentrates, and other particle-shaped, solid materials. ​

In oceans

  1. OXIFORTE facilitates to remove the oceanic or lacustrine red tides.
  2. By adding 100 mg~500 mg of OXIFORTE per Liter of water, the occurrence of red tide can be eliminated in 24 hours.

Application of calcium peroxide in Aquaculture:
  • Adjusting pH value; Calcium peroxide is approved to be efficient in improving the subaqueous pH value and prevent water from acidification.
  • Eliminating carbon dioxide and sulfurated hydrogen; In a pond covered with a ice cap, carbon dioxide usually exists in a big quantity and hinders the oxygen absorption of fishes.
  • Calcium peroxide shows a great effect on elimination carbon dioxide.
  • Calcium peroxide can remove sulfureted hydrogen during its oxygen release process, this improve the water quality at the lower part.
  • Preventing anaerobe from proliferation and killing nosogenetic bacteria, defecating aqueous body; Calcium peroxide is an oxidizer than acts as a disinfectant which may efficiently kill ananerobe and nosogenetic bacteria.
  • Calcium peroxide may facilitate depositing floccules and clearing turbid water thus improves the photosynthesis of natant foliage to increase dissolved oxygen.
  • Providing sufficient dissolved oxygen; This is typically useful for increasing the unit production by enhancing the breeding density at a limited area and solving the problem of oxygen-lacking in some seasons especially winter.
  • Unlike other oxygen release chemicals that release oxygen rapidly, calcium peroxide provides a stable and continued source of oxygen thus it is considered an economical oxygen source for extensive aquaculture applications.
  • Reducing the subaqueous content of ammonium and nitrogen; Ammonium and nitrogen are major factor that prevents fishes from developing, by disseminating calcium peroxide into water, the ammonium and subaqueous content can be remarkably reduced.
  • When dissolved in water, calcium peroxide breaks down into calcium hydroxide, oxygen and water.
  • This characteristic gives calcium peroxide a function as the conditioner of water quality which provides a comfortable environment for aquatic life breeding like fishes, shrimps and crabs.

The benefits for application of calcium peroxide in aquaculture embody in following aspects.
