* Potassium permanganate can kill algae. Precautions When Using Potassium Permanganate. Through the use of potassium permanganate in pretreatment, the substances which cause taste and odor as well as soluble manganese and iron, are oxidized. ozzydom 868 Posted January 26, 2013. ozzydom. The surface area of a square or rectangular pond can be easily estimated by multiplying the pond length by the pond width. For small ponds (less than one acre), application of the chemical can be achieved by first adding a small portion of the total amount of chemical required for treatment to water in a five-gallon plastic bucket, and then broadcasting this solution over the surface of the pond while walking around the pond. Wound Disinfectant. A few helpful reminders and precautions before using potassium permanganate include: Fish farmers may soon have a better way to treat a serious parasitic disease of catfish, known as ich or whitespot. One popular method of treatment is to begin with an application of 2 mg/L potassium permanganate. Common treatment rates are 2 parts per million (ppm) or milligrams per liter (mg/L) for an indefinite pond application or 10 mg/L for a 10-minute tank treatment. Collect five 1-liter samples of the pond water.

Potassium permanganate is an oxidant heavily used in fish culture. trailer Small Fish dalne se phle pond me pani ko jaal chla kar fir uske baad kmno4 dal kar saaf,kar lena chahiye. The average water depth for ponds with a sloped and flat bottom can be determined by averaging the shallowest and deepest water depths. Wait at least four days before repeating treatment. 23 0 obj <> endobj <]/Prev 77471>> 25 acre-feet × 2.7 lbs/acre-foot = 67.5 lbs of potassium permanganate to obtain a concentration of 1 mg/L in the pond. Always use safety protective gear including rubber gloves, goggles and old clothes. Glycerin is the most common, but antifreeze will also do the trick. Actual treatment rates in ponds will vary depending on the amount of organic matter, or organic load, in the water. You have estimated a pond to be 5 surface acres, and the pond has an average depth of 5 feet. Therefore, it is important to properly estimate water volume to achieve both a cost-effective and biologically effective treatment. If used at the correct dose will not kill fish but at higher doses it will kill fish. The 15-minute demand is determined as follows: However, if within a 12-hour period, the pond turns brown, then an additional 1--2 mg/L treatment is required, depending on how quickly the pond turned brown. This value is then multiplied by 2 to give the recommended treatment rate. [7][8]It currently finds application in the control of nuisance organisms such as Zebra mussels in fresh water collection and treatment systems. 0000009886 00000 n If fish do not respond to treatment, reevaluate them to confirm the diagnosis. If there is a question as to which rate has a faint pink color, choose the lower treatment rate. Formalin is used primarily as an external parasiticide on fish and fish eggs as flush, prolonged, or indefinite treatment for fungus control. 58 0 obj <>stream * Potassium permanganate is a strong oxidizer and can burn skin, eyes, and other body parts. ` �{-� Prepare a series of test treatments. 0000001866 00000 n Potassium permanganate is a purple crystal, easily soluble in water and produce concentrated purple solutions. Multiplying the 4 mg/L demand treatment by 2 gives a recommended pond treatment rate of 8 mg/L. Historically it was used to disinfect drinking water. 0000011907 00000 n Potassium permanganate, KMnO4 , is a chemical oxidizing agent that will react with any organic matter in a pond including algae, bacteria, fish, particulate and dissolved organic, and organic bottom sediments. 0000000016 00000 n 5. The primary disadvantage of potassium permanganate is its high cost. Example: 0000011311 00000 n A series of 1-liter pond water samples was treated with potassium permanganate stock solution. After 15 minutes, the 2 mg/L treatment turned brown, but the 4 mg/L treatment still had a faint pink color. It is commonly used to disinfect nauplei and larvae in hatcheries and also culture farms. An important factor to remember is that 1 ppm (or 1 mg/L) is equal to 2.7 pounds of dry chemical per acre-foot of water. The Use of Potassium Permanganate in Fish Ponds 2 shallowest and deepest water depths. In aquaculture, potassium permanganate is used to treat a variety of fish ailments with varying effectiveness via dissolving crystals of the compound in water. 0000007614 00000 n The insoluble manganese and iron are removed by flocculation and filtration. The effects of this compound were examined utilizing molecular (Metallothionein) and whole animal endpoints following an 8-week exposure to nominal concentrations of 0.5 (daily) and 1.0 and 2.0 mg/L (on alternate days) of potassium permanganate (PM). 0000002486 00000 n 0000001016 00000 n This value is referred to as the permanganate value. 0000010618 00000 n 0000001841 00000 n This oxidation process also destroys bacteria and viruses in much the same manner as oxidation with chlorine. Low oxygen conditions can occur following treatment. Underestimating water volume will result in an insufficient concentration of chemical, and retreatment would be necessary. Those same properties make it useful for cleaning and disinfecting human wounds and sores. Potassium permanganate reacts with organic matter and becomes neutralized and unavailable to treat the target parasite. It will stain you and everything it touches brown. The oxidation and bactericidal effect of permanganate does not, … For example, it cost approximately $80 to treat a one-acre pond, with an average depth of 5 feet, at a 4 mg/L concentration. 5 acres × 5 foot average depth = 25 acre-feet of water. Used in Fisheries: As a chemical oxidizing agent, potassium permanganate has also been used in treating diseases in the fish caused by infections of bacterium and fungus or parasite. 6. 0000031625 00000 n 0000014556 00000 n 0000003175 00000 n Contrary to some reports, potassium permanganate does not add significant amounts of oxygen to water and can actually decrease dissolved oxygen concentrations by killing algae that produce much of the oxygen in ponds. In the earlier years potassium permanganate was used in continuous urine infections, vulvovaginitis, vaginal thrush and even vaginal douche after childbirth. it should be mixed with water before use, and then applied evenly over the entire pond surface to ensure an effective treatment. Be prepared to aerate after treatment. startxref Potassium permanganate is commercially available in crystal or powder form. Determining the average depth for ponds with uneven bottoms and widely varying depths requires measurement of water depth at multiple locations in the pond using a simple grid or zig-zag sampling approach, in which all areas of the pond are measured.
