Veolia Seafield Water Re-use
Waterwhelm is developing a commercial scale plant at Seafield WWTW, a major Veolia operated Wastewater Treatment Works in Edinburgh. Following a 2-year pilot study at the same site, Waterwhelm is now developing and subsequently commissioning and operating a commercial scale plant to produce process water for site consumption.The plant has a capacity of 55 m3/day.
The fully integrated system makes use of waste heat extracted from post-boiler flue gases at the site to treat/desalinate and re-use treated wastewater (final effluent). The fully automated system requires minimum maintenance, due to its robust and innovative control system, and once installed can be easily monitored and controlled for purpose.
The deployment of Waterwhelm’s technology with wastewater treatment works (currently 175 sites in the UK) can reduce water demand from these sites and address increasing water scarcity and droughts in various regions. It reduces operational costs and carbon footprint associated with water consumption at wastewater treatment works.
In particular, coupling Waterwhelm’s technology with thermal hydrolysis can lead to multiple advantages for wastewater treatment sites. Here, a unique advantage of Waterwhelm’s technology is being able to return 80-90% of the incoming heat from flue gases to the product water. Once used as boiler feed water directly, or indirectly by heating the existing boiler feed water system, this leads to significant additional CO2 emission savings for the site.
