In order to reduce electricity consumption in wastewater treatment plants (WWTP), the Pronox process is proposed as a variant of the HRAS process. This residue has been developed incorporating simulation tools and experimental research. The Sumo simulator and a 35m3/d capacity pilot plant have been used.
Pronox process: energy savings in WWTP through non-oxidative processes.
In order to reduce electricity consumption in wastewater treatment plants (WWTP), the Pronox process is proposed as a variant of the HRAS process. This residue has been developed incorporating simulation tools and experimental research. The Sumo simulator and a 35m3/d capacity pilot plant have been used. The study focused on studying the optimal operating conditions to derive organic matter and nitrogen. The efficiency of the removal of the different COD fractions in the pilot plant has been studied in detail. The results confirm that the Pronox process, as a substitute for primary settling, can reduce the total electricity consumption in a water treatment plant in the order of 35-50%.
