Combined wastewater treatment, waste incineration and energy production
Growing cities across the globe face challenges in combining municipal and industrial development with safe water disposal and environmental quality. The scarcity and high prices of available land require compact solutions for water treatment infrastructure.
To create a future-proof wastewater treatment system, the Amsterdam water authority Waternet and the Municipality of Amsterdam decided to construct one new large wastewater treatment plant (WWTP) in the Amsterdam West Port Area to replace the former three WWTPs spread around the city centre. This resulted in a new WWTP with a capacity of 1 million population equivalents and 33,000 m3 per day. It incorporates the latest state-of-the-art biological nutrient removal technologies (full biological phosphorus and nitrogen removal) and energy recovery from sludge by biogas production. The WWTP’s energy and residue disposal systems are connected to the neighbouring AEB waste incineration plant, delivering waste sludge and biogas to AEB and receiving electricity and heat in return. The WWTP Amsterdam West also serves as a regional sludge treatment facility and performs phosphate recovery from digested sludge. Thus the first true energy and nutrient recovery WWTP in the Netherlands has been created.
Witteveen+Bos designed the wastewater treatment plant and the sludge processing units and developed the tender documents. Furthermore, we assisted Waternet during the construction phase and coordinated commissioning and start-up.
