| Parameters | Zeoturb | Conventional metal salts Synthetic polymers |
|---|---|---|
| Sludge volume/dewatering | Lower sludge volume, easier dewatering | Higher disposal cost, hazardous materials |
| Contaminants handled | Total Suspended Solids Turbidity Algae Color Trace metals of ferric iron/manganese Reduces DPB's & organic matter | Total Suspended Solids Color Certain Organic Matter Turbidity Can Reduce DPB's in certain cases |
| Sustainability Goals | Yes | No |
| Overall cost | Reduce overall cost (dosage/sludge disposal) | Higher cost of dosage, pH adjustment and typical hazardous sludge disposal |
