Removal of natural organic matter by ultrafiltration and nanofiltration for drinking water production

Water from lake Butoniga near the town of Buzet, Croatia will be used as a source for drinking water production. Since lake water has high concentration of trihalomethane precursors a treatment was necessary. A process including ozonation, flocculation and filtration was chosen on the basis of preliminary work in the trial pilot plant with capacity of 10 m3 h-1. Although the chosen process succeeded in producing water that met the demands for drinking water, the efficiency of natural organic matter (NOM) removal was relatively low. Ultrafiltration (UF) and nanofiltration (NF) processes were investigated as alternatives and possible upgrades of the process. Experiments were conducted on pilot plants with ultrafiltration membranes Mavibran SP 006A and Romicon PM 10, PM 50, GM 80 and PM 500 as well as with nanofiltration membrane Filmtec NF 45. Since most of the organic matter in the lake water was smaller than 6-8 kD, the use of NF process was proposed. To avoid fouling of the NF membrane we used flocculated and filtrated water from the trial plant as NF feed water. This combination produced water of high quality while process parameters remained stable over the whole period of investigation.
