摘要

The fluid is stored in a tank (1) and the additive, which is in solid form (3), is held separately from the fluid (5) in a storage container (2) for controlled delivery to the fluid as required. The additive is stored in portions and introduced into the fluid in the tank while maintaining the separation between the storage container and the tank.
