BWT PURITY PRO XL NEUTRALIZER FILTER
carbon dioxide CO
. It can also be used to remove iron content through the precipitation of iron salts.

Neutralite is used for water with a low aggressive CO
(TA > 20°f) and for intermittent and/or highly variable flow-rate installations. More strongly alkaline,
Magno is preferred over Neutralite for waters with a high aggressive CO
However, the high free alkalinity content of Magno leads to:
- Very high pH water in low-TAC raw water (pH > 8.5);
- The risk of engulfment in the case of raw water with a high TAC in the absence of permanent tapping.

Recommended washing rate
Ground load in operation:
The admissible rates on the neutralizing filters may vary significantly depending on the following parameters:
•
Excess CO
concentration,
2
•
Installation operation mode (continuous or non-continuous),
•
Regularity of operational flow-rates (constant or variable),
•
Iron content of untreated raw water.
Please note that washing rate is higher when the washing processes are less frequent, the TH and Total
Alkalinity Index of the untreated water are high or there is a high level of iron content in the untreated water.

Recommended washing rate
Ground load in operation:
The rate of iron and manganese content reduction depends significantly on the other parameters of the water.
Notably, it is recommended that the total Fe+Mn quantity not exceed 5 mg/L and that the pH of the water to
be treated be greater than 6.5. Treating water that is colloid-rich will also be less effective.
A continuous or sequential injection of chlorine or potassium permanganate may be required to improve
manganese content reduction.
Is used to adjust the pH of the water by neutralising excess
content, for water with a high total alkalinity index
