Experience Rooted in Process Control, Research, and Innovative Problem Solving Solutions

Advanced Water Purification aka Direct Potable Reuse (AWP/DPR)

We have been converting treated wastewater (effluent) into purified potable water for over a decade. We can guide you to an implementation strategy delivering resilient solutions that optimize resource recovery and sustain long-term water security.  In fact, we created Arizona's first advanced water purification demonstration system that ultimately led to ADEQ rulemaking changes allowing for direct potable reuse and currently being enacted in Scottsdale, Phoenix, and Tucson.  The mobile AWP demonstration facility received WateReuse's Project of the Year award and made appearances in Austin, El Paso, Denver, Boise, Tucson, Phoenix, Flagstaff, Prescott, and Yuma along with multiple conference appearances showcasing the technology and public outreach garnering support for reuse and advanced water purification.

Energy Optimization and Decarbonization

We have extensive expertise in wastewater utility operations delivering comprehensive energy audits and practical decarbonization strategies reducing operating costs, improving resiliency, and supporting long-term climate goals. By analyzing energy use across treatment processes and equipment types including pumping, aeration, solids handling, odor control, and resource-recovery systems, we identify high-impact and efficiency opportunities used for developing actionable implementation roadmaps. From utility-scale energy benchmarking to capital planning, we offer renewable-energy integration, electrification, biogas optimization, and emissions reduction strategies helping wastewater agencies convert complex operational data into measurable energy savings using a proven, credible path for lower-carbon emission treatment and resiliency.

Biogas Cleaning and Renewable Natural Gas Production
We specialize in helping wastewater utilities maximize biogas value through integrated optimization and renewable natural gas (RNG) upgrading strategies. We evaluate digester performance, gas quality, energy balances, and operating constraints to increase methane recovery and develop reliable treatment options for removing moisture, hydrogen sulfide, volatile organic compounds (VOCs), and carbon dioxide while purifying methane to pipeline, or vehicle fuel, quality specifications. Our experience includes pressure swing adsorption, membrane separation, water-wash, and amine-scrubbing systems providing technology evaluations, process design support, commissioning assistance, and operational optimization converting biogas into dependable low-carbon energy resource.

Emerging Contaminants and PFAS Treatment
We stay at the forefront of emerging-contaminant research including monitoring and abatement as well as risk-management strategies to help water and wastewater utilities in the protection of public health, maintaining regulatory compliance, and making sound long-term investments. We incorporate source control and prevention approaches along with treatment options and implementation support for addressing contaminants of concern including total trihalomethanes (TTHMs), N-nitroso dimethylamine (NDMA), halo acetic acids (HAAs), microplastics, and per and polyfluoroalkyl substances (PFAS). Our expertise includes source investigations, advanced treatment assessments, pilot testing, monitoring programs, and operational optimization and abatement strategies.

Resource Recovery and Side Stream Treatment
We help wastewater utilities turn everyday treatment challenges into valuable resource opportunities.  We advance nutrient removal along with integrated nutrient recovery options.  In fact, we have been on the leading edge of side stream treatment and recovery strategies, including high-rate ammonia removal, struvite control processes, and phosphorus recovery systems producing reusable fertilizer products.  We can evaluate your treatment performance, nutrient loading, chemical demand, solids loading, regulatory requirements, lifecycle cost, and market considerations to develop practical, facility-specific roadmaps for technologies.  Starting with feasibility studies and design support, to pilot testing through commissioning and optimization, we help clients reduce nutrient loads, prevent uncontrolled scaling, lower operating costs, improve plant capacity, and capture the long-term value of recovered resources.

Anaerobic Digestion and Biogas Safety
We provide specialized expertise in anaerobic digestion system design, optimization, and biogas safety for wastewater utilities seeking to improve solids management, and performance, while recovering more value from their treatment processes.  We provide support integrating robust biogas handling, conditioning, storage, flares, pressure relief, ventilation, gas detection, and hazardous area safety systems. Our experience includes digestion intensification strategies such as thermal hydrolysis to improves solids destruction and reduction of residual biosolids volume, enhances dewaterability, and increases biogas production.  By aligning process performance, energy recovery, safety requirements, and lifecycle economics, we assist clients in developing reliable, resilient digestion systems that lower disposal costs, increase renewable-energy potential, and protect operators and surrounding communities.

Process Optimization, Pilot Testing, and Commissioning
We provide end-to-end treatment process expertise, guiding clients from early-stage concept development through bench-scale evaluation, pilot testing, full-scale design, commissioning, and long-term optimization.  We develop comprehensive testing programs for evaluating technology performance under site-specific conditions that translate results into practical, scalable process solutions with clear capital, operations and compliance implications. Our team can support you in technology selection, process modeling, design criteria development, procurement, construction-phase services, start-up, operator training, and performance verification helping utilities and industrial clients reduce implementation risk and achieve reliable, optimized treatment outcomes.
