CIE has patented a special technology called PUR-ALL, which is a chemical-physical process used for specific water treatment plants for fluorides and sulphates removal. The main purpose of this system is infact the abatement of sulphates, fluorides and aluminum, in order to obtain clean water from these elements, and therefore reusable.
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
ALUMINUM
