Eliminating Odors in Drinking Water: Adjusting the Amount of Activated Carbon

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.

Why Use Activated Carbon to Remove Odors?

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.

Adjusting the Amount of Activated Carbon Based on Flow Rate

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.

Adjusting the Amount of Activated Carbon Based on Water Volume

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.

How to Choose the Right Filtration System with Activated Carbon

To effectively eliminate odors, choose a filtration system with an activated carbon filter tailored to your household needs. Here are some tips:

  • Evaluate the flow rate of your setup to determine filter capacity.
  • Consider the daily water volume consumed.
  • Opt for high-quality filters that offer sufficient contact surface with the activated carbon.

Advantages of Using Activated Carbon for Water Treatment

Activated carbon provides several benefits for water treatment:

  • Removes unpleasant odors and tastes.
  • Reduces organic contaminants and chemicals.
  • Improves drinking water quality for more enjoyable daily consumption.

Maintenance Tips for Activated Carbon Filters

To ensure continuous efficiency, activated carbon filters require regular maintenance. Here are some maintenance tips:

  • Replace the activated carbon according to the manufacturer's recommendations, typically every 6 to 12 months.
  • Monitor water quality to detect any return of undesirable odors or tastes.
  • Perform regular water testing to ensure the filter is functioning properly.

 

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
