Operating Cost

Definition

Operating cost refers to the expenses associated with the day-to-day functioning of a system or process, including costs for labor, materials, utilities, and maintenance. In the context of membrane systems, operating costs play a crucial role in determining the economic feasibility and overall efficiency of the system, impacting decisions on design, scale, and optimization to ensure sustainable operation over time.
