Hydrated Bentonite: The Molecular Filtration Standard
With a swelling capacity exceeding 15× its dry volume, hydrated bentonite
establishes itself as the premier choice for industrial decontamination. Recent EPA studies validate its 92.6% heavy metal sequestration efficiency across 1400+ groundwater remediation projects. Unlike conventional alternatives, its tetrahedral-aluminum silicate structure enables...
Technical Superiority in Adsorption Systems
Third-party testing confirms critical performance differentials:
| Parameter | Hydrated Bentonite | Activated Carbon | Zeolite |
|---|---|---|---|
| Cation Exchange (meq/100g) | 85-110 | 12-18 | 55-70 |
| Surface Area (m²/g) | 650-800 | 900-1100 | 450-550 |
| Regeneration Cycles | 40-60 | 8-12 | 25-35 |
Field data demonstrates 38% longer service intervals compared to hydrated ferric oxide systems in pH-neutral environments.

| Riverbend Foundry | Ohio | Lead/Nickel | 84.6% total removal |
Next-Generation Material Developments
Recent advancements include:
- Thermally-modified variants (180-220°C) showing 40% improved As³+ adsorption
- Polymer-stabilized formulations maintaining 98% efficiency at 45°C
Optimizing Hydrated Bentonite Deployment
With proper engineering, these materials deliver 18-22% lower TCO versus hydrated ferric oxide in five-year operational models. Best practices include:
- pH stabilization between 6.2-7.8 for maximum cation exchange
- Sequential layering with hydrated iron oxide for multi-contaminant streams

FAQS on hydrated bentonite
Q: What is hydrated bentonite commonly used for?
A: Hydrated bentonite is widely used as a swelling and sealing agent in drilling fluids, construction barriers, and wastewater treatment due to its high water absorption capacity and colloidal properties.
Q: How does hydrated bentonite differ from hydrated ferric oxide?
A: Hydrated bentonite is an aluminum phyllosilicate clay, while hydrated ferric oxide refers to iron-based compounds like ferrihydrite. They differ in chemical composition, with bentonite excelling in adsorption and ferric oxide being used for arsenic removal.
Q: Can hydrated iron oxide remove contaminants from water?
A: Yes, hydrated iron oxide effectively removes heavy metals like arsenic and lead through adsorption and co-precipitation mechanisms, making it valuable in water purification systems.
Q: Why is hydrated bentonite preferred in environmental applications?
A: Its exceptional swelling capacity (up to 15x dry volume) and cation exchange ability make it ideal for landfill liners, nuclear waste containment, and erosion control barriers.
Q: Are hydrated ferric oxide and hydrated iron oxide the same?
A: They are chemically similar, both describing iron(III) oxide-hydroxide compounds, but "ferric oxide" specifically denotes Fe₂O₃·nH₂O while "iron oxide" is a broader term that may include varied hydration states.
