A METHOD AND A SYSTEM FOR ENHANCING NITROGEN REMOVAL IN A GRANULAR SEQUENCING BATCH REACTOR (GSBR) AND A COMPUTER PROGRAM PRODUCT

摘要

A method and a system for enhancing Nitrogen removal in a granular sequencing batch reactor (GSBR)and a computer program product The method comprises applying a control strategy including a closed DO control loop with a variable DO concentration set-point and a DO concentration measurement performed at the GSBR, on-line measuring the ammonium concentration in the effluent of the GSBR during an operating cycle of the GSBR and calculating a constant DO concentration set-point value for a consecutive operating cycle based on the result of said ammonium concentration measurement. The system is adapted for performing the method of the invention. The computer program product comprises code instructions for the automatic calculation of the DO concentration set-point value.
