PAC is widely used in water and wastewater treatment, but choosing a PAC product is not simply a matter of selecting the highest aluminium content.
Raw water quality, turbidity, pH, suspended solids and the treatment process can all affect the result.
A product that works well in one treatment system may not give the same performance in another. This is why water treatment operators normally consider the actual water conditions before deciding on a PAC specification.
For buyers, testing a suitable grade on a small scale before a large order can be a practical step.
Good chemical selection starts with the water itself, not just the product label.
