CREW for wastewater operators

Optimize your operations

We know that the first priority of wastewater treatment is meeting requirements for public safety and the environment. We’re here to help you do that — and more.

With CREW, wastewater facilities can surpass compliance and actively demonstrate a commitment to environmental stewardship.

Our process streamlines treatment, improves cost efficiency, and reduces your carbon footprint — aligning better environmental outcomes with a better bottom line.

The result is a solution that benefits your facility and serves your community.

CREW’s process intensification

Alkalinity enhancement

CREW’s installation enables the utility to operate in Alkalinity-Enhanced Mode™ (AEM): the operational state of a biological wastewater treatment process characterized by elevated, consistent, and actively managed alkalinity and pH conditions relative to conventional operation to achieve process intensification.

Cost-savings with CREW over traditional chemical treatment:

85%

Realize process benefits

By replacing expensive, hazardous, and carbon-intensive chemicals like caustic soda or quicklime, CREW delivers safer, more consistent treatment at a lower cost and lower carbon footprint than standard methods.

While facilities currently using alkaline chemicals achieve significant cost savings, all utilities can achieve cost savings with increased treatment capacity, reduced aeration needs, reduced need for other chemicals like coagulants, and other benefits.

CREW Carbon primary sensor

End-to-end measurement

Our platform and sensor arrays quantify both the process benefits gained and CO2 removed in real time, generating carbon credits — the next phase of resource recovery.

With CREW, wastewater facilities can optimize operations, lowering opex and capex, as they take a step toward decarbonization.

Our approach

Operational benefits of alkalinity enhancement:

  • Optimized performance

    CREW’s process intensification technology drives more consistent biological treatment, better nutrient removal, and improved settleability, and our high-resolution monitoring and modeling provides robust, applicable process insights.

  • Cost savings

    We provide compounding opex savings, using a more cost-effective alternative to replace caustic and reduce alum and polymers. Wastewater partners have seen opex savings translate to significant capex savings.

  • Enhanced safety

    Our solution eliminates risk exposure for operators by replacing conventional, hazardous chemicals.

  • Efficient compliance

    CREW’s technology results in stable, more consistent biological and nutrient treatment, which leads to better effluent quality to help facilities meet permit regulations.

  • Environmental impact

    We reduce facilities’ carbon footprint by replacing carbon-intensive chemicals with locally-sourced minerals as well as reducing process emissions.

Wastewater operator partners

Our partner facilities worldwide are currently realizing process benefits, gaining cost-efficiency and actively removing carbon from the environment.

“The combined approach also enhances biomass settling for an intensification benefit, while simultaneously providing very low secondary effluent turbidity — a challenge for other competing approaches. The overall solution is transformational for facilities attempting to do biological nitrogen and/or phosphorus removal under the typical alkalinity-limited conditions experienced at many treatment plants. As we extend this approach to our Virginia Initiative Plant, we expect significant capital and operational savings for HRSD.”
