Chemical-physical plants for water purification by metal precipitation and neutralization of acids and alkaline.
PUR-ALL is based on a combined action between a chemical additive (PUR-ALL 03S) and application technology. Thanks to that combination, Sulfates and Fluorides are precipitated as ‘total insoluble complex’ of Al3O3, CaO, CaSO4, CaF2.
PUR-ALL process, allow to leave waste water with extremely low pollution
- Sulphates: ≤ 150 ppm
- Fluorides: ≤2 ppm
- Conductivity: ≤ 400 µS/cm
PUR-ALL find its application on any acidic section containing H2SO4 and HF such as:
- Aluminum Anodizing and Painting
- Stainless Steel Pickling
- Aluminum Cans & Coil
PUR-ALL technology is Barium and Barium salts free
PUR-ALL is also propaedeutic to ZLD (Zero Liquid Discharge) technology
This Technology is applicable to the following fields
