PWA Process Water Treatment
Process water treatment for dry-cut systems
The process water treatment unit PWA serves to filter, temper, and circulate process water for dry-cut systems in centrifugal pellet dryers of underwater pelletizing systems during compound and masterbatch production. PWA can be integrated into the base frame of the cooling trough or positioned externally. Using a heat exchanger, the PWA separates the contaminated process water circuit from the primary cooling circuit from the central water supply.
