Advantages of Konda Fluoride Removal Water Purification Filter Media KD-1
1. Extended Service Life**: KD-1 filter media lasts 5-10 times longer than other filter media.
2. Easy Assembly**: KD-1 equipment is easy to set up; simply fill a sufficiently large tank with KD-1 filter media. Water enters from the bottom and exits from the top, achieving purification without the need for complex installations.
3. Simple Management**: Regenerating KD-1 filter media requires only immersing or circulating a regeneration solution through the exchange tower—eliminating the need for complex processes like acid-base neutralization required by activated alumina and hydroxyapatite.
4. Short Regeneration Time**: The KD-1 filter media can be regenerated in less than 2 hours. The process is simple, and the media can be reused immediately without cleaning, with no need for standby tanks, saving costs.
5. Long Service Life**: While most fluoride removal materials last less than two years, KD-1 filter media has a lifespan of 3-5 years.
Technical Specifications of KD-1 Fluoride Removal Filter Media:
1. Purification Method**: Utilizes adsorption, catalysis, and ion exchange processes.
2. Operating Method**: Upward water flow for filtration and upward flow for regeneration.
3. Filtration Rate**: 5-8 m³ per hour, with a recommended filter layer height of 1.5 meters and a maximum of 2.8 meters. Alternatively, the optimal water purification rate is 2-5 tons per hour per ton of KD-1, with a maximum capacity of 5 tons per hour. The diameter of the exchange tower need not be a constraint; the media can be filled in any shape—short and wide or tall and narrow.
4. Total Adsorption Capacity**: 1000–1500 mg/kg (KD-1).
5. Regeneration**: For each ton of filter media, 70 kg of regeneration agent dissolved in water (110% of the filter media volume) is required. If the media is already wet, the water volume in the regeneration solution should equal 70% of the media volume. Slowly introduce the solution into the exchange tower and let it soak or circulate for 100 minutes before discharging. All solution must be released within 2 hours, after which the media can immediately enter the next production cycle without washing.
6. Density**: Bulk density of KD-1 is 1.1.
7. Chemical Dosing**: Adding a dosing tank before water intake can extend the regeneration cycle by 5-10 times.
8. Dosing Options**: Our proprietary Formula 1 or Formula 2 agents, which can be sourced locally, are recommended for the dosing tank.
Summary of Main Fluoride Removal Methods Worldwide and Their Pros and Cons:
1. Anion Resin Ion Exchange: Due to the selectivity of the resin, fluoride removal efficiency is low. The complex and costly regeneration process makes this method rarely used today.
2. Activated Carbon Adsorption: Limited fluoride adsorption capacity and inability to regenerate result in high operational costs, which is generally unacceptable.
3. Hydroxyapatite (Bone Char) Adsorption: Effective in fluoride adsorption, but high material costs, low durability, and complex management, along with an unpleasant odor in treated water, limit its application, leading to it being largely phased out.
4. Activated Alumina Adsorption: Widely used but has drawbacks, including short operational cycles, complex regeneration, and the risk of aluminum exceeding safe levels in the treated water, posing potential health risks.
5. Electrodialysis: Provides thorough fluoride removal with high water quality, but high equipment and energy costs make it challenging to adopt widely.
6. Reverse Osmosis: Achieves effective fluoride removal, but the high operational costs, low production rate, and large wastewater output make it suitable only for high-purity or bottled water production rather than public water supply facilities.
7. Aluminum-based Coagulation Precipitation: Difficult to control dosing, resulting in significant aluminum contamination in treated water, has led to its gradual elimination.
8. Zeolite Adsorption: Directly using zeolite for fluoride removal has limited efficiency and cost-effectiveness, so it is seldom applied.
In summary, various fluoride removal methods show limitations in cost, management, and efficiency. Huludao Konda Group, in collaboration with experts from Harbin Institute of Technology and Tongji University, developed the KD-1 fluoride removal filter media. KD-1 is easy to use, simple to manage, long-lasting, and has been widely accepted by manufacturers, earning recognition as a nationally prioritized environmental material.
The company adheres to a high-tech, pollution-free development strategy, leveraging the abundant non-metallic mineral resources provided by nature. In collaboration with multiple research institutions, including Harbin Institute of Technology, Tongji University, and the Chinese Academy of Agricultural Sciences, the company has been recognized as a national priority for the promotion of new environmental materials in areas such as drinking water purification, wastewater treatment, air pollution control, air health products, soil improvement, and soil heavy metal pollution remediation.
