Unpleasant odors in drinking water are often due to compounds such as hydrogen sulfide, responsible for rotten egg smells, or other organic and chemical substances. Using activated carbon is an effective solution to absorb these odors and purify the water. However, the amount of activated carbon needed depends on two factors: water flow rate and the volume of water to be treated.
Activated carbon is widely used for removing odors and contaminants in drinking water. Thanks to its adsorption properties, it effectively captures compounds responsible for unpleasant smells, such as volatile organic compounds (VOCs) and chemicals like hydrogen sulfide. Activated carbon acts like a sponge, trapping unwanted particles that cause odors.
The water flow rate is a key factor in determining the required amount of activated carbon. If the flow rate is high, water passes quickly through the filter, reducing the contact time between water and activated carbon. For a higher flow rate, it’s often recommended to increase the amount of activated carbon or choose filters with greater capacity to ensure optimal odor removal.
The volume of water to be treated also affects the amount of activated carbon needed. A larger volume of water may require a greater amount of carbon to maintain filtration efficiency over a prolonged period. For high water consumption, it’s advisable to increase the activated carbon filter capacity to prevent media saturation and ensure odor-free water.
To effectively eliminate odors, choose a filtration system with an activated carbon filter tailored to your household needs. Here are some tips:
Activated carbon provides several benefits for water treatment:
To ensure continuous efficiency, activated carbon filters require regular maintenance. Here are some maintenance tips:
Common Drinking Water Odor Issues
Rotten egg smell, musty odors, earthy, moldy, grassy, fishy, vegetable, or cucumber-like smells | Hydrogen sulfide, sulfate-reducing bacteria, soft water reactions in electric water heaters, algae byproducts, bacteria, surfactants |
Oil odor | Gasoline or oil contamination, possibly harmful bacteria |
Methane with a gas-like smell | Organic decomposition – note that natural gas has no odor, but the natural gas supplied to your home contains sulfur compounds (mercaptans) added to create a strong odor to help detect leaks. |
Phenolic odor | Industrial contamination or gasoline |
Chemical odor | Organic chemicals, industry |
