Potassium Permanganate use in aquaculture (KMnO4)
Potassium permanganate is a strong
oxidizing chemical. It removes parasites, as well as fungal and bacterial
agents. For most fish, potassium permanganate can be used at a concentration of 1-2 mg/L as a long-term
bath (four-hour minimum) in fresh water and salt water systems. Potassium permanganate is
also reasonably safe to use in recirculating systems and has minimal impact on
biofilters when used at 2 mg/L. Treated water should retain the purple coloration
for at least four hours.
Calculation
If we want to use KMnO4 @1mg/liter
(or 1.0 ppm) in 1.0 cubic meter (1m3 = 1meter length x 1meter width
x 1 meter height of water volume = It contains 1000 liters of water ).
1.0 m3 =1000 liters of water
1ppm=1mg/liter
Rate of application is one mg in one liter
Therefore, for 1000 liters of water
the amount required will be 1000 mg ( because 1.0 mg KMnO4 will be
applied in one liters so 1000 mgwill be required for one thousand liters of
water
Or
1mgx1000 liter= Quantity will be 1000
mg
1000mg=1.0gram
Ans: Quantity required of KMnO4
in 1.0m3 of water volume when applied @1.0ppm will be 1000mg
or 1.0 grams.
