Municipal Nutrient Removal Wastewater
Go beyond basic BOD removal. We design and remotely optimize systems to meet the most stringent total nitrogen (TN) and total phosphorus (TP) limits, protecting receiving waters and avoiding non-compliance penalties.
Is Nutrient Removal Your Biggest Operational Headache?
| Challenge Category | Description |
| Tightening Regulations | Facing new permits requiring Total N < 5mg/L and Total P < 0.2mg/L, or even lower “nutrient-sensitive” limits. |
| Seasonal & Load Variations | Struggling to maintain consistent removal rates with fluctuating temperatures and influent loads. |
| High Chemical Costs | Over-reliance on chemical precipitation for phosphorus, leading to high OPEX and increased sludge volume. |
| Limited Plant Footprint | Needing to add advanced treatment steps without space for large new tanks. |
A Tiered, Remotely-Tuned Approach to Low-Level Nutrients
Retrofit existing activated sludge basins with Moving Bed Biofilm Reactor (MBBR) media. This increases biomass concentration and creates ideal anoxic/oxic zones for simultaneous nitrification-denitrification and biological phosphorus removal, all guided by our remote process analytics.
Increase nitrogen removal capacity by 30-50% in same tank volume | Reduce chemical P precipitant use by up to 60%.
For final polishing, employ deep-bed Denitrification Filters that remove residual nitrate and particulate phosphorus. Our remote chemical dosing optimization system precisely controls precipitant (e.g., ferric chloride) addition to achieve ultra-low TP with minimal chemical waste.
Achieve effluent TN < 3 mg/L and TP < 0.1 mg/L | Automated, remote chemical dose adjustment based on real-time influent data.

Your Nutrient Removal Process, Optimized from Afar
Nutrient balance is dynamic. Our Moore Cloud™ platform continuously analyzes your plant data (DO, ORP, nitrate, flow). Our experts provide remote tuning recommendations for aeration, internal recycle, and chemical feed to ensure optimal performance 24/7, adapting to daily and seasonal changes.
Proven Reductions in Nutrient Loading and Cost
| Metric | Achievements |
| Permit Compliance | 100% permit compliance on N&P parameters post-upgrade. |
| Operational Cost | 20-40% reduction in phosphorus removal chemical costs through bio-P enhancement and smart dosing. |
| Carbon Source Savings | Up to 35% reduction in external carbon source (e.g., methanol) for denitrification through process optimization. |
| Management Efficiency | Real-time nutrient dashboards replace daily lab tests, speeding up response time. |
