The maximum capacity of an industrial RO plant can vary significantly depending on the specific model and design. Typically, these plants can process anywhere from thousands to millions of liters of water per day. The capacity is determined by factors such as the size and number of membranes, the design of the system, and the operational requirements of the application. For example, large-scale industrial operations, such as power plants or large manufacturing facilities, may require RO systems with capacities exceeding several million liters per day to meet their extensive water needs. On the other hand, smaller industrial operations may find systems with lower capacities more suitable for their requirements.
