Natural Organic Matter (NOM) in surface water usually refers to humic and fulvic acids that are decayed by-products of plants such as those found in surface waters shallow well aquifers. AMBERLITE™ PWA-9 and an innovative, very wide pore resin designated DOWEX™ TAN-1 should be considered for NOM removal needs. These resins can help reduce color, trihalomethanes (THM’s) and other similar disinfection by-products (DBP’s) that can be formed during chlorination processes.
