What does NOM stand for in water treatment?

Natural Organic Material (NOM) refers to the naturally occurring organic compounds found in water sources such as rivers, lakes, and groundwater. These materials can originate from a variety of sources, including plant decay, soil, and microbial activity. NOM plays a significant role in water treatment processes because it can influence the formation of disinfection byproducts during chlorination and can affect the overall quality of water.

Understanding NOM is essential for water operators as it impacts treatment decisions and strategies. For instance, high levels of NOM may require advanced treatment techniques such as enhanced coagulation or activated carbon adsorption to ensure that water is safe for consumption. Being knowledgeable about NOM helps operators manage the challenges associated with water quality, adhering to regulations, and protecting public health.
