Reverse Osmosis will effectively remove viruses from water.

Reverse osmosis (RO) is a filtration process that uses a semi-permeable membrane to remove various contaminants from water, including dissolved salts, organics, and many microorganisms. However, while RO is effective at reducing the number of bacteria and some larger viruses, it does not guarantee complete removal of all viruses from water.

The reason the statement is considered false is that the effectiveness of reverse osmosis in removing viruses depends on several factors, including the size of the virus, the type of RO membrane used, and the specific operating conditions. Some smaller viruses may pass through the membrane, especially if there are defects or if the membrane has been compromised.

While the RO process can significantly reduce virus concentration, achieving complete and consistent removal of viruses often requires additional treatment methods. Techniques such as UV disinfection or additional filtration systems specifically designed for viral removal can enhance water safety, indicating that relying solely on RO for complete virus removal may not be sufficient.

Thus, understanding the limitations of reverse osmosis in this context is crucial for ensuring water safety and making informed decisions about water treatment options.
