This application is suitable for among other the Freebac-Clearoxyl® product.

a) Continuously:
When a fresh quantity of water is continuously added to the process water, an amount of Freebac-Clearoxyl® can be automatically added to the process water by means of an injection unit.

b) Variable:
In case of a variable flow, for example during production interruptions or the use of only a part of the capacity, Freebac-Clearoxyl® can be added flow related.

When the water is circulated, it must be verified whether the flow is continuous or variable and whether flow-related injection is required. The concentration of Freebac-Clearoxyl® that remains after the circulation time can be determined with measuring strips.
