Abstract: 

Water is vital for human survival, health, and dignity and a fundamental resource for human development. Around 70 percent of our body is made up of water. So, for our daily life, we need to make sure about having clean water. Contaminated water can cause high-risk diseases for human beings sometimes it could be a reason for a person to die. Illnesses like Hepatitis, Cholera, Diarrhea, etc. are caused by contaminated water which could affect other people easily. Today there are several methods to get access to clean water, the methods used for water purification include physical processes such as filtration, sedimentation, and distillation; biological processes such as slow sand filters or biologically active carbon; chemical processes such as flocculation and chlorination; and the use of electromagnetic radiation such as ultraviolet light. Trusted technology for water purification is Nanofiltration(r-GO) technology and Reverse Osmosis (RO). GO technology has attracted many researchers because of its unique hydrophilicity properties and its cost-effectiveness in mass-scale production. The r-GO membrane is one of the nanofiltration technologies that has the advantages of partial removal of monovalent ions, low process osmotic pressure, low operating pressure Energy saving, and other advantages.
