Trust in results
From our 2022 pilot to current deployments in the U.S. and Europe, CREW is helping wastewater treatment facilities improve performance, increase capacity, and remove greenhouse gasses.
Trickling Filter Facility – South Platte Renew
25MGD
- Coming soon
EBPR Facility – Northwest U.S.
45MGD
- Replaced costly and carbon-intensive alkalinity source
- Improved SVIs by operating above baseline alkalinity setpoints
- Reduced downstream ferric usage in tertiary facility and anaerobic digestion
EBNR Facility – Northeast U.S.
16MGD
- Improved nitrogen removal efficiency, allowing the potential to generate additional revenue from the sale of nitrogen credits
- Increased dry cake solids percentage to optimize belt presses and pelletizer
- Reduced RAS pumping rates
- Verified CO2 removal project
High-Purity Oxygen Facility – Northeast U.S.
25MGD
- Reduced SVI 50-70% and filamentous bulking
- Prevented TSS excursions during wet weather events
- Saving hundreds of thousands of dollars on sodium hypochlorite, sodium bisulfite, and dewatering polymers
- Verified CO2 removal project
5-Stage Bardenpho Facility – Northeast U.S.
40MGD
- Improvements in SVI in winter months, when settling is historically more challenging
- Improved nitrogen removal discharging to a sensitive water-body
- Strengthened operational reliability by avoiding pH swings
- Verified CO2 removal project
EBPR Facilities – Hampton Roads Sanitation District (HRSD)
10MGD
- Deferred construction of a tertiary/polishing plant by consistently meeting stringent effluent nitrogen and phosphorus limits
- Maintained low SVI in summer months, when treatment is historically more challenging
- Prevented filamentous bulking events throughout the winter
- Saved on sodium hydroxide and ferric chloride costs
- Verified CO2 removal project
CREW’s approach not only augments pH and alkalinity but also improves process stability, reducing the risk of extreme fluctuations and overshooting. This keeps your biology happy and helps keep your plant in compliance.
