6. Good water management practices in paper mills
When we talk about water management in paper mills, we need to take a global view of all water circuits: the process water circuit (fabric water and clarified water), the clear water circuit and effluents.
6.1 Process water management strategies
The water circuit of the paper machine is managed in a loop (figure 6):
