What is the term for the liquid produced from the reverse osmosis process that has a low concentration of dissolved solids?

Permeate refers to the liquid that has passed through the reverse osmosis membrane and is characterized by a low concentration of dissolved solids. During the reverse osmosis process, water molecules are forced through a semi-permeable membrane, while larger molecules and impurities, or contaminants, are effectively retained on the feed side of the membrane. The resulting permeate is typically cleaner and purer than the original water source, making it suitable for various uses, including drinking water or further treatment in wastewater processes.

Understanding the role of permeate is essential in wastewater treatment and water purification processes, as it highlights the effectiveness of reverse osmosis in removing contaminants and reducing total dissolved solids in the resulting water. This concept is critical for those working in the field of wastewater treatment to ensure compliance with environmental regulations and to maintain water quality standards.
