Microbial contamination and its consequences

Furthermore, there is a risk of uncontrolled deposition (biofilms), which, for example in paper production, could lead to holes and breaks in the paper web. 

Clearly, the need for biocide(s) to initiate, preserve and maintain slurry purity is a very important part of the slurry producer s and handler s requirements for efficient application and storage of minerals. 

The target, therefore, is not only microbial control vrithin the product itself but also the control within the confines of the immediate product-contacting environment. 

To meet today s logistic requirements, slurry tank vessels with a capacity of up to 16,000 registered tonnes are in operation.
