Introduction
Activated Carbon Block (CTO) filters have become increasingly popular in water treatment applications, offering an effective solution for removing chlorine, taste, odor, and various organic compounds. This comprehensive guide explores CTO filtration technology, its applications, and how it compares to other filtration methods.
What is a CTO Filter?
A CTO (Activated Carbon Block) filter is a specialized water filtration device manufactured from compressed activated carbon derived from coconut shells or coal. These filters feature a unique structure with microscopic pores that effectively trap contaminants while allowing water to flow through. The compressed nature of CTO filters provides superior filtration compared to loose carbon media, offering:What is CTO Activated Carbon?
CTO activated carbon is a specialized form of activated carbon derived from coconut shells or coal through a precise carbonization and activation process. The material undergoes careful temperature control and chemical activation to develop a highly porous structure with superior adsorption capabilities. This unique manufacturing process results in a high-performance filtration medium specifically designed for water treatment applications, featuring exceptional chlorine removal efficiency and superior contaminant reduction capabilities.| Item | Activated Carbon for CTO |
| Particle size | 200mesh, 50*70mesh, 30*80mesh |
| Iodine value | 900-1100mg/g |
| CTC | ≥50% |
| Ash | 5% max |
| Moisture | 5% max |
| Hardness | ≥98% |
What is the Difference Between CTO and UDF Filter?
CTO (Compressed Carbon Block) and UDF (Granular Activated Carbon) filters represent two different approaches to water filtration, each with distinct characteristics and applications.
Basic Structure and Function
| Feature | UDF Filter | CTO Filter |
|---|---|---|
| Carbon Form | Granular | Compressed block |
| Water Flow Rate | Higher flow | Lower flow (about 50% of UDF) |
| Filtration Accuracy | Lower precision | Higher precision |
| Carbon Powder Release | May release some powder | Minimal powder release |
| Adsorption Capacity | Larger capacity | Limited by block structure |
| Process Length | Longer contact time | Shorter contact time |
| Best Position | Secondary filtration | Pre-filtration |
Application and Benefits
UDF FilterUDF filters use granular activated carbon for secondary filtration in water purification systems. Their loose structure provides longer contact time with water, making them highly effective at removing odors and improving taste. With higher water flow rates and larger adsorption capacity, UDF filters are ideal for applications needing efficient contaminant removal and better water output.
CTO Filter
CTO filters, made of compressed carbon blocks, excel in pre-filtration stages. They offer precise filtration while removing chlorine and preventing membrane clogging. Though they have lower flow rates than UDF filters, their compact structure prevents carbon powder release and provides reliable initial stage filtration.
Conclusion:
CTO filters represent a significant advancement in water filtration technology, offering superior performance in chlorine removal, taste improvement, and organic compound reduction. Their unique properties make them an excellent choice for both residential and commercial applications.Looking for high-quality CTO filters or activated carbon solutions?
