Scope
Description
Anglian Water Services Ltd ("Anglian Water") is assessing future delivery models for Nitrate Removal Solutions as part of its ongoing commitment to delivering high-quality drinking water and meeting stringent environmental regulations. Effective nitrate removal is critical to maintaining compliance and protecting water quality across our supply regions.
Nitrate levels in source waters across the UK are rising, creating an urgent need for advanced, innovative solutions to ensure safe drinking water for millions. To tackle this challenge, Anglian Water is launching a major investment programme to enhance and upgrade Ion Exchange plants (IX) across the region.
Currently, these IX plants generate brine waste, which is discharged via 3 different routes:
Tankered and discharged to a number of Water Recycling Centres (WRCs),
To Foul Sewer (discharging into our Water Recycling Centres) via AW 'Internal [trade effluent] Permits
Direct discharges to river/sea where Permits are in place for this.
However, Anglian Water is committed to driving efficiency, sustainability, and delivering better value for its customers. That's why we are seeking forward-thinking partners to help revolutionise the future of water treatment.
We are looking for innovative alternatives including Ion Exchange technology that offer greater efficiency and cost-effectiveness. In addition, due to increased brine production in AMP8 and beyond we want to explore new resource recovery methods for brine waste, reducing environmental impact and unlocking valuable opportunities.
