Ultrafiltration for water treatment plant, TP 104-25

and filter for Pitkäkoski water treatment plant (WTP). Long-term goal for the ultrafiltration pilot is to evaluate ultrafiltration paired with chemical precipitation as a primary natural organic matter (NOM) removal method when purifying cold surface water. Membrane performance and water quality is

compared to that of a clarification and sand filtration. Purchased UF process will be preceded by a separate chemical dozing and flocculation unit to ensure effective NOM removal and membrane applicability in variable conditions. Different
