AMP has seen some stringent consents for total phosphorus (TP) with 0.25 mg/l being commonly applied with some lower consents of 0.16 mg/l or lower. The industry is also working with the regulator on the Nitrogen Technically Achievable Limits (NTAL) trials which will assess the concentrations of total nitrogen that can be achieved without major changes to wastewater treatment assets. Haskoning has previously presented on trials dosing upfront of the Nereda process to meet low TP consents at Walsall Wood and Failsworth WwTW’s. This presentation will go into further details on the mechanisms of removal and share further operational data from the UK and internationally. Options for meeting lower standards than 0.25 mg/l will be discussed, including how Nereda can be combined with Ultra-filtration or other tertiary treatment options and how this compares to MBR on w whole life cost basis. Regarding Nitrogen, a number of Nereda sites are included within the NTAL programme, including Barston where a purpose-built reactor will use design modifications to achieve the lowest possible TN without carbon addition. TN data will be shared for UK and international sites and the operational parameters and advanced process control strategies that influence low TN performance will be discussed; (i) feed and aeration phase lengths are adapted to load; (ii) DO setpoints are modulated—higher while NH₄ is elevated to avoid nitrite accumulation and nitrifier‑denitrification, then tapered to promote anoxic zones for denitrification once NH₄ drops; and (iii) interchange ratios and upflow velocities are tuned to sustain granular integrity
