Nanofiltration (NF) membrane method - a new water treatment technology This paper introduces a new water treatment technology - nanofiltration membrane method, and briefly explains its development overview, characteristics, separation mechanism and application in the field of water treatment. Water treatment technology separates or transforms pollutants contained in sewage and wastewater through various corresponding measures, thereby reducing pollution and protecting the environment. Traditional sewage and wastewater treatment technologies are divided into physical methods, chemical methods and microbial methods according to different treatment principles. Commonly used physical methods include distillation and mechanical separation methods; chemical methods are divided into chemical treatment methods, ion exchange treatment methods, activated carbon adsorption, etc. With the development of social economy and the improvement of people\'s living standards, people have higher and higher requirements for environmental quality. Traditional sewage and wastewater treatment technologies are difficult to meet the requirements of today\'s sewage discharge standards. Various new, improved and efficient sewage and wastewater treatment technologies have emerged. Nanofiltration (Nanofiltration, referred to as N membrane technology is one of the eye-catching technologies.
