Calcium Peroxide Granule

Tranditionally, calcium peroxide is a white or yellowish solid peroxide which slowly decomposes to release oxygen at a "controlled" rate when in contact of hydrous media.
Calcium peroxide based chemical oxygen product is of the most temperature stable inorganic oxygen release compounds. It is practically insoluble in water, and dissolves in acids, forming hydrogen peroxide and calcium hydroxide.

In addition to tranditional fine powder form of calcium peroxide, we also developed granules form of calcium peroxide for your final application. The advantages this unique form of calcium peroxide:

Comparing with fine powder form material which is difficult to handle and floats in water. it make difficult or impossible to handle when it is desired to treat large water bodies or the sediment or bottom. etc of a water body when water is present wihtout special effort and care, such as by draining the water. Our unique solid form calcium peroxide (granule, briquette, tablet, prill, flake, pellet, etc) is not a powder, and is engineered to have a higher bulk density such that it easily settles to the bottom of the water body to be treated and thus comes into contact with any residue, sediments etc. located at the bottom of such water body. this granlues are easily mixed with soils or sediments for ex situ treatment. In addition, granules form exhibit an oxygen release profilee that is slower then the powder, leading to prolonged activity after a single application. thus reducing the frequency of re-application.

This unique granule form sinks in water preferably, it has a much lower surface area than fine powder fom, this contributes to a reduction in dissolution rate of the active ingredients embedded in the solid form, easy to be dispensed or spreaded over wide areas of water body. it does not disintegrate quickly or easily due to higher degree of compaction.

Slow release of corresponding metals ion in water e.g.Ca from calcium peroxide (reaction with anions such as nitrate,carbonate, carbon dixoide, sulfate, phosphate etc. leading to insoluable salts whic reducues acidity, leads to phosphate immobilization. reduces photosynthesis due to reduction in CO2, and can lead to reduced water conductivity; Providing a source of calcium that is adsorbed by living organisms to sustain life).

Some preferred uses and benefits include:

  • Maintenance of a good level of dissolved oxygen in water bodies especially at sediment, despite higher summer temperatures that reduce oxygen soluiblity in water, and very lower winter temperatures that lead to ice convering on water bodies preventing oxygen adsorption from atmosphere.
  • High overall water quality taht encourages a diversity of plant and amimal life. enhances the recreational value of the body of water, and prevents fish kills.
  • Healthier fish propulation which thrives in better quality water, especially bottom dwelling creatures such as catfish and shrimp with increase in feeding rate leading to large fish.
  • Reduced activity by reaction with acids such as organic acids especially in aquaculture ponds improves water quality for fish.
  • Enhanced aerobic microbial degradation of orgain matter leading to a reduction in Biologicdal Oxygen Demand (BOD) in water, sediment, manure, sewage etc.
  • Enhanced growth of nitrifying bacteria which convert ammonia to nitrite, leading to reduced ammonia odor.
  • Enhanced oxidation of organic matter leading to reduction in Chemical Oxygen Demand (COD) and toxicity.
  • Enhanced water clarity.
  • Reduction in anaerobic bacteria thrus preventing anaerobic degradation of organic matter and avoiding putrification.
  • Reduction of filamentous baceteria thus causing debulking.
  • Enhanced zooplankton population due to higher assimilation of products obtained form aerobic degradation.
  • Immobilization of heavy metals such as Fe, Mn, Cu and As.
  • Elimination of unpleasant ordors (oxidation of reduced sulfur species and elimination of ammonia produced under anaerobic conditions)
  • Better pH control (alkalinity prevents accumulation of organic acids and carbon dioxide and reacts with other anions in water).
  • Reduced sediment levels due to enhanced biodegradation of organic matter can eliminate the neef ofr expensive dredging. Dredging is underiable not only because it is expensive, but also because it release toximc metals in water druing the dreging operation. If dredging is still necessary, the sedimennt dredged would be of reduced toxicity and could be reused e.g., as a fertilizer or for another applicaiton.
