Drinking Water Treatment Activated Carbon
- Organic compounds (pesticides, solvents, taste/odor chemicals)
- Disinfection byproducts (THMs)
- Chlorine (improving taste/odor)
- Some microplastics and emerging contaminants.
Industry Challenges
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.
