GELF Sciences turns wastewater into valuable resources


Brett Danson

Brett is recognized worldwide as an expert in advanced environmental sciences. Brett has developed collaborative relationships with some of the world’s top environmental scientists over the past five years and has negotiated agreements with governmental agencies to purify wastewater.

Brett is educated in multiple science disciplines, water and wastewater treatment techniques, and sustainable financial business modeling. 

"We are developing waste to energy systems that employ sustainable, financial business models. The projects make sense both financially and environmentally."


Bruce Rittmann PhD.

  Dr. Bruce Rittmann, Ph.D., is the director of the Swette Center for Environmental Biotechnology at the Biodesign Institute at Arizona State University and is also a Regents' Professor in the School of Sustainable Engineering and Built Environment.    

An international leader in managing microbial communities, Dr. Rittmann's work is leading to new ways to clean up pollution, treat water and wastewater, capture renewable energy, and improve human health. 

 "We manage microorganisms to provide services for society, services to aid us directly or to aid us with interactions with the natural environment 


Cesar Torres PhD

 Dr. Cesar I. Torres is an Associate Professor of Chemical Engineering in the School for Engineering of Matter, Transport and Energy at Arizona State University and part of the Chemical Engineering and the Civil, Environmental and Sustainable Engineering Graduate Program faculty. Cesar is a leader in microbial electrochemical cell research, focusing on microbial kinetics of anode-respiring bacteria (ARB) and extracellular electron transport to and from solid electrodes. He has published 15 articles in peer-reviewed journals on this topic. Torres combines biofilm modeling, electrochemical, microscopic, and analytical techniques, to characterize ARB kinetics and thermodynamics.

Environmental Biotechnology Water-Energy Nexus; Environmental Biotechnology; Water Resource Recovery; Microbial Electrochemistry; Water and Wastewater Treatment; Environmental Remediation; Carbon Capture and Utilization; Water Desalination; Membranes 


Pei Xu PhD

Our work focuses on developing innovative technologies to augment water supplies from alternative water resources (e.g., municipal wastewater, brackish water, produced water, desalination concentrate, and other impaired waters) while balancing energy consumption, economic benefits, ecological impacts, and social acceptance. Our research areas include water and wastewater engineering; membrane processes; desalination; potable and non-potable water reuse; produced water treatment; oxidation and photocatalysis; biological and bioelectrochemical processes; removal of emerging contaminants; and membrane fouling.


Sunny Jiang PhD

 Dr. Sunny Jiang is professor and Chair of the Department of Civil and Environmental Engineering at University of California, Irvine.  She also serves as the Associate Director for UC Irvine Water and Energy Nexus Center. During her career at UCI, she has focused her research on microbiological water quality, engineered and natural water treatment including seawater desalination, and quantitative microbial risk assessment (QMRA). Her group has pioneered the molecular detection system for rapid human pathogens identification in water and contributed to the US EPA’s policy decision on water quality and human health protection in water reuse and water recreation. 


Department of Interior Bureau of Reclamation Brackish Groundwater National Desalination Research Facility (BGNDRF)

 Our agreements with BGNDRF allow us access to U.S. Department of Interior Bureau of Reclamation (Reclamation) laboratory testing facility, engineers and scientists.  Reclamation provides scientific and engineering expertise as projects scale by providing feasibility studies, testing , testing facilities and third party validation.
