Bentonite for Industrial Water and Wastewater TreatmentBentonite is a layered mineral mainly composed of montmorillonite. Its large surface area, ion-exchange capacity and swelling behavior make it a useful functional material in selected water-treatment processes.
HERMANO Water Treatment Bentonite is supplied for industrial applications where a mineral adsorbent, clarification aid or process-support material is required. The appropriate grade should be selected according to water chemistry, contaminant type, process design and target treatment result.
Typical Applications Industrial wastewater clarification
Suspended-solid separation and settling support
Oily wastewater pre-treatment
Dyeing, printing and textile wastewater treatment
Mining and mineral-processing wastewater
Paper-making wastewater treatment
Chemical-process wastewater treatment
Sludge conditioning and dewatering support
Adsorption support for selected oils, color bodies and dissolved contaminants
Water-treatment filter media and mineral treatment blends
Key Benefits High montmorillonite content and controlled mineral quality
Fine particle size available for effective dispersion
Large mineral surface area for adsorption-oriented applications
Supports settling and solids-handling processes in selected systems
Natural and sodium-activated grades available
Grade selection can be adjusted according to water chemistry and process requirements
Bulk and bag packaging available for industrial use

Water treatment is highly dependent on the actual wastewater composition. Bentonite should be tested in the complete process rather than selected only by one parameter.
