Water quality compatibility with cleaning

The formulations presented in this section are based on the type of wastewater reuse described above, where wastewater is produced from a cleaning operation and reused in product. However, due to the fact that product integrity is a high priority a number of conditions must be ensured. Firstly, the reuse of wastewater contaminated with a certain residue can only be reused in compatible product. In most instances, this is the same product as the residue. Secondly, wastewater containing different contaminants cannot be stored at the same time in the same storage vessel. Finally, the water used for a cleaning operation has to be of the same quality as water used in product.
