Which oxidation chemical is used to treat taste and odor related to algae in surface water?

Potassium permanganate is specifically effective in treating taste and odor issues related to algae in surface water due to its strong oxidizing properties. It helps to control the growth of algae and breakdown associated organic compounds that contribute to unpleasant tastes and odors. Potassium permanganate oxidizes the organic materials produced by algae, thus improving water quality and making it more palatable.

While chlorine and sodium hypochlorite are commonly used disinfectants, they may not be as effective in addressing taste and odor problems linked to algae when used alone. Hydrogen peroxide, on the other hand, is also an oxidizer but is more typically employed for its disinfection capabilities and less frequently used specifically for algae-related taste and odor control.

Therefore, potassium permanganate stands out as the optimal choice for effectively managing algae-related issues in surface water.
