Activated Carbon

Product Overview

Activated Carbon is a specialized filtration media used in swimming pool water treatment to remove odors, color, and organic contaminants from pool water. As a member of the water clarification and flocculation chemical category, activated carbon consists of carbon granules that have been processed to create an extremely porous structure, providing exceptional adsorption capacity for a wide range of impurities.

Activated carbon is one of the most versatile water treatment media available. Its ability to adsorb organic compounds, remove unpleasant odors, eliminate discoloration, and reduce chlorine demand makes it invaluable for pools facing specific water quality challenges. Unlike chemical treatments that add substances to the water, activated carbon works by physically removing contaminants through adsorption, making it a “subtractive” treatment method.

The product is used as filtration support media, typically placed in the filter system or in a dedicated carbon filter. Water passes through the carbon bed, where contaminants are adsorbed onto the carbon surface. Over time, the carbon becomes saturated and must be replaced or regenerated.

In the pool maintenance industry, activated carbon is recognized for its effectiveness in addressing specific issues such as:

• Removal of chloramine odors (“chlorine smell”)
• Elimination of color from organic staining (tannins, humic acids)
• Reduction of chlorine demand from organic contaminants
• Improvement of overall water quality in challenging conditions

Activated carbon is not a routine maintenance product for most pools. Instead, it is used as a targeted treatment for specific water quality problems or as part of a specialized filtration system for pools with challenging source water.

Egret Swimming Pools supplies activated carbon media to residential and commercial pool owners across Kenya who need effective removal of odors, colors, and organic contaminants. As a trusted pool chemical supplier based in Kihunguro, Ruiru, we provide quality filtration support products backed by expert technical advice.

How It Works

Activated carbon operates through a sophisticated adsorption mechanism that removes contaminants from water without adding chemicals. Understanding this mechanism helps pool owners appreciate why activated carbon is so effective for specific water quality challenges.

The Structure of Activated Carbon:

Activated carbon is produced by heating carbonaceous materials (such as coconut shells, wood, or coal) in the absence of oxygen, then activating them through steam or chemical treatment. This process creates an incredibly porous structure with an enormous surface area:

• Surface Area: 500-1500 m² per gram (equivalent to several football fields)
• Pore Structure: Micro-pores, meso-pores, and macro-pores of varying sizes
• Internal Surface: Contains functional groups that attract and bind contaminants

The Adsorption Mechanism:

1. Physical Adsorption:
   Contaminant molecules are attracted to the carbon surface through weak van der Waals forces. The carbon’s extensive surface area provides countless sites for this physical attraction. Larger molecules are trapped in the pores, while smaller molecules adsorb onto the pore walls.
2. Chemical Adsorption (Chemisorption):
   Some contaminant molecules form stronger chemical bonds with the carbon surface. This chemisorption is particularly important for certain organic compounds and can be less reversible than physical adsorption.
3. Filtering of Larger Particles:
   In addition to adsorption, the carbon granules also provide mechanical filtration, trapping larger particles that would otherwise pass through the filter media.

Contaminants Removed by Activated Carbon:

Contaminant Type	Examples	Removal Efficiency
Chloramines	Combined chlorine compounds	High
Organic compounds	Tannins, humic acids, oils	High
Odors	“Chlorine smell,” musty odors	High
Discoloration	Yellow/brown tint from organics	High
Chlorine	Free chlorine (for dechlorination)	High
Pesticides/Herbicides	Agricultural runoff	Moderate-High

Saturation and Replacement:

As contaminants are adsorbed, the carbon surface becomes progressively occupied. Once all adsorption sites are filled, the carbon is saturated and no longer effective. Saturated carbon must be replaced with fresh media or, in some cases, regenerated through thermal or chemical processes.

Why It Matters

Activated carbon addresses specific water quality challenges that chemical treatments alone cannot resolve:

• Chloramine Removal:
  The “chlorine smell” often associated with swimming pools is actually caused by chloramines—combined chlorine compounds formed when chlorine reacts with ammonia, urea, and other nitrogenous compounds from swimmers. Chloramines cause eye irritation, skin reactions, and unpleasant odors. Activated carbon effectively removes chloramines, eliminating the odor and improving swimmer comfort.
• Odor Elimination:
  Beyond chloramine odor, pools can develop musty, earthy, or chemical odors from various organic compounds. Activated carbon adsorbs these odor-causing molecules, restoring a fresh, pleasant swimming environment.
• Color Removal:
  Tannins and humic acids from leaves, soil, and vegetation can tint pool water yellow or brown. This discoloration is particularly problematic in areas with significant organic material in the source water or surrounding environment. Activated carbon removes these color-causing compounds, restoring water clarity.
• Reduced Chlorine Demand:
  Organic contaminants consume chlorine, increasing chemical costs and making water chemistry more difficult to manage. By removing organics, activated carbon reduces chlorine demand, allowing sanitizer to work more efficiently.
• Improved Water Quality:
  The combination of contaminant removal leads to overall improved water quality—water that is clearer, more pleasant to swim in, and easier to maintain.
• Environmental Consideration:
  Activated carbon removes contaminants without adding chemicals to the water. This “green” approach to water treatment appeals to environmentally conscious pool operators.
• Specialized Solution:
  For pools with specific water quality challenges (e.g., well water with organics, pools near vegetation, high bather load facilities), activated carbon provides a targeted solution that other treatments cannot match.
