Uses of activated alumina

Activated alumina can be used as a point-of-entry or point-of-use water treatment device. Activated alumina absorbs contaminants instead of filtering them. The effectiveness of activated alumina depends on the contaminant, characteristics of the …

EFFECTIVE AGAINST: Dissolved iron and manganese, and hydrogen sulfide.

Uses of potassium permanganate

Potassium permanganate is a point-of-entry treatment method that oxidizes dissolved iron, manganese, and hydrogen sulfide into solid particles that are …

EFFECTIVE AGAINST: Pathogenic (disease-causing) organisms including bacteria and viruses, phenols, some color, taste and odor problems, iron and manganese, and turbidity.

NOT EFFECTIVE AGAINST: Large cysts and some other large organisms, inorganic chemicals, and heavy metals.

…

EFFECTIVE AGAINST: Small particles and suspended solids such as ferric iron, clay, silt and sand, and some pathogens such as bacteria and viruses, and colloids (suspended matter).

NOT EFFECTIVE AGAINST: Any dissolved contaminants such as nitrate, dissolved iron, sodium, and volatile organic compounds (VOCs).

EFFECTIVE AGAINST: Some heavy metals, dissolved solids, some bacteria and viruses, inorganic materials such as nitrate, sodium, fluoride, and sulfate, and some toxic organic chemicals.

NOT EFFECTIVE AGAINST: Most volatile and semi-volatile organic compounds (VOCs), and some bacteria.

Chlorination may be effective in removing pathogens, including certain viruses and bacteria, from your well water system.

EFFECTIVE AGAINST: Pathogens, including certain viruses and bacteria.

…

EFFECTIVE AGAINST: Positively charged ions such as iron, magnesium, calcium or manganese.

NOT EFFECTIVE AGAINST: Negatively charged ions, such as nitrates, bicarbonate, sulfate, selenium, and some compounds of arsenic.

…

EFFECTIVE AGAINST: Negatively charge ions, such as nitrates, bicarbonate, sulfate, selenium, and some compounds of arsenic.

NOT EFFECTIVE AGAINST: Positively charged ions such as iron, magnesium, calcium or manganese.

…

EFFECTIVE AGAINST: Aeration water treatment is effective for management of dissolved gases such as radon, carbon dioxide, some taste and odor problems such as methane, and hydrogen sulfide, as well as volatile organic compounds, like MTBE or industrial solvents. It is also effective in precipitating dissolved iron and manganese. Aeration raises the pH of water.

NOT EFFECTIVE AGAINST: Aeration is not effective for removal of heavy metals, or pathogenic (disease-causing) organisms like bacteria and viruses.
