Boosting Water Quality with Oxidants

2013-04-08

Oxidants are crucial in aquaculture, whether used as disinfectants or to improve water quality. Various oxidants are utilized in aquaculture operations, including chlorine compounds like calcium hypochlorite, potassium permanganate, hydrogen peroxide, sodium carbonate peroxyhydrate, calcium peroxide, and sodium nitrate. In emergencies, hydrogen peroxide and sodium carbonate peroxyhydrate can serve as sources of dissolved oxygen.

 

Utilize Oxidants for Pond Water Disinfection and Enhanced Water Quality Parameters

No. Item
 Description
 Data of Research Case Cons
 Spotlight
 Conclusion
1 Potassium Permanganate
 • Oxidizing organic matter in ponds
 • The amounts of potassium permanganate required for removing 1 mg/L of hydrogen sulfide or ferrous iron are 6.19 and 0.94 mg/L, respectively.

• Kill phytoplankton

 

• Lower dissolved-oxygen concentrations

• Remove hydrogen sulfate and ferrous

 

• Treating external fungal and bacterial infections on eggs and fish

 • Not a useful water quality enhancer
2 Sodium Nitrate
 •  Be used as a fertilizer to encourage diatoms in shrimp ponds
 •  The redox is very high, so that the anaerobic bacteria can not produce ferrous and hydrogen sulfide.

• Expensive

 

• No molecular oxygen will be released

 • Beneficial to water quality in ponds
•  Sediment Oxidant
3 Hydrogen Peroxide

• Generate molecular oxygen

• Avoid the concentrations of hydrogen perxide above 5mg/L for more than a few hours.

 

• One drop, about 0.5 mL, of 6% hydrogen peroxide should provide about 1.5 mg/L of dissolved oxygen in 1 L of water.

   • Generate molecular oxygen
 • Excellent molecular oxygen release and water quality enhancer
4 Sodium Carbonate Peroxyhydrate

•  The carrier of hydrogen peroxide

•  Water flow through trout raceways often is as rapid as 3 exchanges/hour.

 

•  Provide 1.5 mg/L dissolved oxygen in a 1-m-deep, 1-ha pond would require 500 L of 6% hydrogen peroxide

 

• It would be hazardous to use hydrogen peroxide solutions stronger than 20 to 30% at most aquaculture facilities.

  

• Emergency sources of dissolved oxygen in ponds

 

• Less safety hazards

 •  Excellent water quality enhancer
5 Calcium Peroxide

• Generate molecular oxygen

 

• Increase PH and total alkalinity

• One mg of calcium peroxide will release about 0.22 mg of oxygen.

 

• In Japan, calcium peroxide has been applied to sediment in eel ponds at 25-100 g/m2 at monthly.

 

• Each milligram of calcium peroxide can potentially generate about 1.39 mg of total hardness and total alkalinity. 

  

• Generate molecular oxygen

 

• Less hazardous to store and handle

 • Excellent water quality enhancer
