Plant description

The Galindo WWTP is designed for C and N removal and handles a daily average wastewater flow of 345600 m3/day. The WWTP is divided into six identical lines and the configuration in each of them can be operated as one of two alternative configurations: Regeneration-Denitrification-Nitrification (RDN) and Denitrification-Regeneration-Denitrification-Nitrification (DRDN).

Commissioned by

Consorcio de Aguas Bilbao-Bizkaia

Executed by

CEIT

Goal

The afore-mentioned project consisted of the full-scale implementation of three advanced control strategies:

• To control the effluent ammonia by means of the selection of the DO set point.
• To maintain the plant in the optimum denitrification potential by means of the internal recycle.
• To maintain a constant solids mass value by means of waste flow rate manipulation

Results

The control was successfully implemented on the real plant. Resulting in a more stable and cost effective operation.
