- Organic compounds (pesticides, solvents, taste/odor chemicals)
- Disinfection byproducts (THMs)
- Chlorine (improving taste/odor)
- Some microplastics and emerging contaminants.
行业挑战
Technical Limitations
- Performance Variability: Adsorption efficiency declines over time due to pore blockage and competitive adsorption (e.g., calcium accumulation), complicating performance evaluation.
- Selective Removal: Effectively removes chlorine, organic compounds, and disinfection byproducts (e.g., haloacetic acids) but struggles with nitrates, certain bacteria, and some PFAS (only ~50% reduction). It also shows limited efficacy against trihalomethane precursors.
- Ozonation Byproducts: When combined with ozone (O₃-BAC process), it risks generating bromate or aldehydes if not meticulously controlled.
Operational & Environmental Issues
- Biofilm Risks: Biological activated carbon (BAC) filters may cause microbial leakage if biofilm management fails, compromising water safety.
- Material Degradation: Regeneration of spent carbon remains technically challenging; acid/base washing is often needed but not universally effective.
- Resource Constraints: Production relies on restricted raw materials (e.g., coal, coconut shells), with quality inconsistencies affecting output.
Regulatory and Industry Gaps
- Standardization Deficits: Lack of uniform evaluation metrics (e.g., reliance on iodine/methylene blue values alone ignores granularity effects) and evolving regulations challenge consistent compliance.
- Supply Chain Pressures: Stricter environmental policies increase production costs and limit material sourcing options.

工艺与技术
1. Adsorption of Organic Micropollutants
解决方案概述
Activated carbon (AC) in granular (GAC) or powdered (PAC) form physically adsorbs persistent organic contaminants like pesticides and pharmaceuticals through its porous structure.
主要优势
- Broad-spectrum removal of diverse micropollutants
- Chemical-free treatment mechanism
- Flexible deployment options (direct dosing or fixed-bed filtration)
2. Combined Oxidation-Biological Processes
解决方案概述
Ozone or permanganate pre-oxidation followed by Biological Activated Carbon (BAC) filtration, where oxidation breaks complex organics into biodegradable fragments metabolized by AC-colonized biofilms.
主要优势
- Enhanced removal of recalcitrant compounds via biodegradation
- Extended operational lifespan through biological regeneration
- Synergistic contaminant removal efficiency
3. Disinfection Byproduct Control
解决方案概述
AC filters capture natural organic matter (DBP precursors) and adsorb formed byproducts like trihalomethanes at pre- or post-disinfection stages.
主要优势
- Dual-action against precursors and formed byproducts
- Regulatory compliance support without disinfection compromise
- Reduced reformation potential during chlorination
4. Long-Term Biological Filtration
解决方案概述
Aged GAC transitions into biological filters where microbial communities dominantly degrade organic matter, sustaining performance beyond adsorption capacity.
主要优势
- Self-sustaining operation through microbial activity
- Temperature-resilient performance in warm conditions
- Reduced waste generation via extended service life
