Activated Carbon for Swimming Pools

activated carbon for swimming pool

You may be familiar with swimming, but do you know how the water in swimming pools is treated?

Swimming pool water treatment systems generally include hair filters, coagulation and dosing devices, circulation pumps, mechanical filters, activated carbon filters, and disinfection and dosing devices.

As an excellent supplier of activated carbon, we understand that activated carbon can effectively remove organic matter, chloramines, odors, impurities, and other pollutants from water. This article will focus on the application of activated carbon in swimming pool water.

Common Problems in Swimming Pool Water

Swimming pools, being public places, are susceptible to contamination.

Pool water pollution can be broadly categorized into two main types: organic and inorganic. Inorganic pollution, such as excess iron causing yellow water or manganese exceeding standards resulting in ink-colored water, is a significant cause of water discoloration.

Organic pollution is a complex part, involving both natural factors like rainwater, leaves, and insects, as well as pollutants introduced by humans, such as disinfectants, algaecides, and water purifiers added to maintain pool cleanliness and hygiene. Additionally, contaminants from swimmers, such as body exfoliation and personal items, contribute to organic pollution.

All these factors can lead to deteriorating water quality, affecting the health of swimmers and the lifespan of pool facilities. To ensure clean and hygienic pool water, regular cleaning is essential. Activated carbon, as an excellent adsorbent, plays a crucial role in cleaning pool water.

Application of Activated Carbon

Activated Carbon for Swimming Pools

Activated carbon, with its outstanding adsorption capabilities, efficiently removes organic matter, odors, residual chlorine, and other pollutants from water. In swimming pool water treatment, the introduction of an activated carbon filtration system can rapidly purify water, ensuring swimmers can enjoy a refreshing swim in clear and transparent water.

The adsorption by activated carbon is primarily a physical process. Therefore, used activated carbon can be regenerated by high-temperature steam to remove impurities, making it reusable and economically beneficial.

Improving Water Clarity

Extended periods of unclean pool water can lead to water discoloration. Activated carbon is crucial in restoring the pool water to its natural, colorless state.

Removing Odors

The odors in swimming pool water mainly result from the reaction of chlorine and organic compounds, producing volatile organic compounds (VOCs). Using activated carbon can quickly neutralize and adsorb these odorous substances, enhancing the swimming experience.

Enhancing Water Quality Stability

Incorporating activated carbon into the water treatment process for chlorine disinfection in swimming pools can eliminate some disinfection by-products. It not only removes impurities from the water but also contributes to maintaining water quality stability. Its adsorption of residual chlorine helps prevent concentration fluctuations, ensuring a safe and stable level of chlorine in the pool water, and providing a healthy and safe swimming environment.

Energy-Efficient and Environmentally Friendly Choice

Compared to traditional water treatment methods, activated carbon filtration systems are more energy-efficient. Its high adsorption performance means it can reduce energy consumption while maintaining water quality, making it environmentally friendly and aligning with modern society’s demand for sustainability.

Selecting the Right Activated Carbon

For swimming pool use, we primarily offer columnar carbon and granular carbon made from high-quality smokeless coal or coconut shells. After activation and advanced processing, the activated carbon exhibits excellent adsorption performance, high strength, ease of regeneration, developed porosity, and a large surface area.
