Wastewater treatment plants are designed for input data considered constant and are checked for maximum values according to the imposed loads. During operation, the values of flows and loads at the wastewater treatment plant entrance point change within wide limits. In order to achieve the treatment efficiency, exploitation measures are adopted to ensure the water discharge within the legal admissible limits. These safety measures involve additional operating costs or risk in discharging water with quality indicators not allowed compared to those required by current legislation. Technological adjustment mechanisms must be provided in the design and operation stages. The present paper highlights a procedure for technological processes regulating when occurs significant loads variation at the wastewater treatment plant entrance point and demonstrates its importance.
