Clear Savings, Proven Impacts
Knowldege + Experience = Real Results.
Our Experience Case Study Examples
We introduced the first advanced water treatment process in Arizona producing high-quality drinking water from treated wastewater effluent. The collaborative project included Pima County, Tucson Water, Cities of Phoenix, Flagstaff, Scottsdale, Town of Marana, and ADEQ. The project was instrumental for changing state regulations allowing for direct potable reuse and provided the ideal vehicle for education and public outreach, including the AZ PURE Brew Challenge and receiving the WateReuse Project of the Year, and AZ Forward Governor's Crescordia Award for Environmental Excellence.

Struvite Control


NuReSys Struvite Abatement Process
Struvite is an unfortunate menace almost every wastewater treatment plant encounters. Common strategies included the use of corrosive ferric slats and substantial dilution post dewatering for combating struvite.
The price of ferric salts has increased by over 300% in recent years so many utilities are exploring alternative options. We led a very successful pilot demonstration of the MagPrex process for struvite control and ultimately opted for the first full-scale implementation of the NuReSys process in North America for struvite precipitation.
Modern process like Ostara, MagPrex and NuReSys break the anaerobic digestion phosphorus recycle loop decreasing struvite formation while enhancing biosolids dewatering.
The project was also a recipient of AZ Forward Governor's Crescordia Award for Environmental Excellence.

Sidestream Deammonification




AnitaMOX Pilot Demonstrations
Designed, constructed, and operated a pilot demonstration of the anammox process for the treatment of concentrated ammonia rich centrate waste after the dewatering of biosolids. Electrical costs associated with aerobic treatment of wastewater is the typically the largest operational cost for most utilities, often representing 50% - 60% of overall electrical usage. Sidestream wastes following the dewatering of anaerobically digested biosolids contain high concentrations of ammonia thereby increasing overall aeration costs.
The annamox process provides considerable savings by treating sidestream wastes including the following:
Biogas Upgrading to RNG


Biogas Upgrading Processes
Biogas conversion to RNG represents the latest efforts in resource recovery and is practiced at fewer than 40 wastewater treatment facilities. Our team members have extensive experience, even chairing WEF's RNG Task Force and hosting annual biogas and RNG workshops at WEF conferences. Our expertise spans creation of RFPs, negotiating interconnect operating agreements, RIN generation, safety procedures and staff training. Our members led a nationwide coalition of authors in the creation of reference manual for the boots on the ground operators and maintenance personnel entrusted with these systems. The book title is Guidelines for the Safe Operations for Biogas and RNG Facilities and is available through WEF's online bookstore at

Energy Reduction and Decarbonization
PFAS Treatment and Destruction


Biosolids and Land Application
90% ammonia removal in side stream wastes
60% savings for aeration oxygen demand compared to conventional BNR processes
90% reduction in biomass production compared to conventional BNR processes
Energy consumption as low as 1.1kWh/kg of nitrogen removed
Can be highly automated for operational ease
The project represents the first AnitaMOX installation in Arizona!

Once again Arizona is leading the way in the evaluation of innovative solutions for reducing PFAS concentrations in wastewater effluent. We are conducting pilot demonstrations to evaluate the effectiveness of foam fractionation, followed by electro-oxidation, for the removal and destruction of PFAS. This valuable work represents the first real-world demonstration of PFAS treatment in a wastewater process. Preliminary results indicate up to 60% reduction in overall effluent PFAS concentrations have been achieved making it a cost-effective option for wastewater treatment.




Wastewater treatment often represents the largest energy expenditure for many municipalities and energy costs are expected to rise substantially for meeting demands. Understanding where energy is consumed throughout your facility, and individual equipment demands within those processes is the key step towards initiating changes.
We have developed proven strategies for benchmarking utility usage and optimizing energy usage. We will create an intelligent systems roadmap for reducing your energy usage and achieving decarbonization goals. We start by evaluating your data systems and performing a comprehensive process evaluation for prioritizing opportunities and developing an implementation strategy.
We will evaluate demand management and process equipment in the creation of the implementation strategy for achieving the greatest energy reduction along with a scoring matrix for ease of implementation.

Land application of biosolids is practiced by over 50% of municipalities nationwide as an effective nutrient rich fertilizer improving both soil health and crop yield. In Arizona, that figure approaches 90% along with 30% contributions imported from California. Urban encroachment on agricultural lands can make long term planning difficult and increase operational expenses for utilities.
Public perception and scrutiny over potential contaminants are always present requiring agencies to be forever diligent in monitoring biosolids quality to address public safety concerns. We are actively involved with CASA, NEBRA, WRF and WEF advancing research on contaminants, soil mobility and crop uptake and serve on advisory committees for many of these projects. Let us help you secure an effective biosolids management strategy that meets your immediate needs and future planning




Wastewater treatment plants have become modern industrial resource recovery facilities producing numerous public benefits including recycled water, renewable natural gas, power generation, and agricultural fertilizers.
This graphic provides a simplistic depiction demonstrating the synergistic relationship between energy inputs and the many renewable outputs that can be achieved.
We can help optimize your resource recovery strategies along with energy reduction options for approaching energy neutral resource recovery throughout Arizona.
