pH neutral operation

Unlike aluminium or iron salts, Q-TAN does not alter pH and reduces the need for pH correction

Sludge reduction

Produces larger, denser flocs—cutting sludge volumes and related costs

Safe and sustainable

Fully biodegradable, non-corrosive, and heavy-metal-free

Effective at low dosages

Outperforms traditional coagulants at significantly lower dosing levels

Nature-powered performance in water treatment

Q-TAN leverages the power of natural tannins to offer a high-efficiency coagulation solution for oily, fatty, and starchy wastewaters. It's especially valuable in petrochemical, food, and recycling sectors where mineral coagulants fall short. Available in 100% vegetal or enhanced mineral trace variants, Q-TAN is built for the future of sustainable water management

Where Q-TAN makes an impact

Open all Close all

Petrochemical industry

Q-TAN is highly effective at treating wastewater with high loads of fats, oils, and hydrocarbons. It improves water clarity while reducing chemical use and sludge volume in refinery and petrochemical effluents.

Food & Beverage processing

Ideal for facilities handling high-starch and organic-rich wastewater, Q-TAN offers efficient coagulation without altering pH. It supports clean discharge and lower sludge output from washing, processing, and cooking stages.

Recycling & Packaging

Q-TAN handles complex wastewater streams containing inks, adhesives, and fibrous content. Its performance in these systems makes it an ideal choice for paper and packaging recyclers aiming to meet tighter environmental targets.

Biological sludge treatment

By improving floc density and reducing volume, Q-TAN enhances sludge dewatering and conditioning, making disposal or reuse more efficient – especially in biological wastewater treatment systems.
