Natural waters, groundwaters and surface waters, often contain elevated concentrations of natural organic matter (NOM) due to geological composition or biological decomposition of plant and animal material in the water. The most significant component of natural organic matter are humic substances. Humic substances are undesirable in water because they cause appearance of color, taste and smell. Because of their molecule structure (long carbon chains and/or rings, humic substances often bind a variety of contaminants(heavy metals, pesticides). Significant problem is the heightened concentrations of humic substances since they form toxic and carcinogenic by-products trihalomethanes(THMs) during the water disinfection with chlorine. Humic substances are complex mixtures of organic compounds with different structure, molecular weight, number and position of functional groups depending on the origin and age of the organic material, the type of water, environmental and climatic conditions which results in a different reactivity with chlorine so called trihalomethane formation potential (THMFP). Membrane processes are efficient methods for ions, colloids and solids removal from water based on their molecular weight and chemical structure. This study investigated the effect of membrane filtration via various membrane types (microfiltration, ultrafiltration, nanofiltration and reverse osmosis membranes) on THMFP reduction. Effect of membrane type on pH, electrical conductivity (EC), alkalinity, water hardness and KMnO4 consumption were also analyzed.
