Raw Water Treatment
Paper mills need water for many purposes.  In many cases, the source water (river, lake or well) will require some treatment before use. In many cases, this is simple clarification with or without filtration. These are very straightforward systems that UCC and help design and supply.
Demineralized Water Treatment
Some paper mills produce their own steam. In these cases they will need demineralized water for boiler makeup. In most cases this means two pass reverse osmosis with polishing via mixed bed ion exchange or EDI. In many cases, this equipment is straightforward and fairly standard, but in some cases there site specific challenges such as poor influent quality, limits on overall system recovery, etc. UCC has the capabilities and experience to surmount these challenges.
Dewatering
All of the water treatment systems mentioned above will require some sort of dewatering – plate and frame filter presses, centrifuges, belt presses, etc. UCC is very familiar with this equipment and excels at selecting the correct technology for the application.
Overall Site Water Balance Optimization and Reuse
Industry has begun to realize that water should not simply be divided into ‘influent’ and ‘effluent’ but should be considered as a resource be managed and minimized throughout the facility. An overall site water balance can be used to track water quality as it flows through the facility. Water costs money and such a tool is helpful in identifying opportunities for reuse. At a paper mill, this not only saves on the water itself, but often affects the heat balance. Energy is saved because the reused water is warmer (already heated in the mill) when compared to raw water.
