Our clients rely on our diverse experience:

• MWH has performed and provided support for more than 100 bench-, pilot- and demonstration-scale studies that support cost-effective solutions to environmental challenges across a wide-range of treatment processes. These include conventional treatment, direct filtration, membrane filtration, ion exchange, granular activated carbon adsorption and filtration, ozonation, advanced oxidation and air stripping, coagulation, softening, water and wastewater disinfection, disinfection byproduct mitigation, and bio- and biodegradation kinetics.
• Our researchers have performed extensive studies to evaluate the application of innovative ceramic membranes in water treatment and reclamation for enhanced energy utilization efficiency, including operating the first ceramic pilot in the United States to demonstrate long-term operation and efficiency.
• We’ve earned respect as a leader within the field. MWH employees serve on national committees, have won a wide range of awards, have published more than 200 articles in peer-reviewed journals and technical conferences and maintain close relationships with major universities and research institutions around the world, including the WateReuse Foundation, National Water Research Institute and the Water Environment Research Foundation (WERF).
• MWH conducted a pilot study to evaluate the operational performance of two different membrane systems, pressurized microfiltration (MF) and submerged ultrafiltration (UF), to determine the effectiveness of different pretreatment configurations on membrane fouling and target goals.
• We have conducted process evaluation of almost every membrane bioreactor (MBR) system currently marketed in the United States and more than 85 percent of membrane systems approved by the California Department of Public Health have gone through our rigorous evaluation program.
• MWH and a major United States wastewater facility evaluated an advanced wastewater treatment UF/RO/UV-AOP pilot process train for production of potable-quality recycled water.
• Our research team provided characterization of United States seawater and developed standardized protocols for the evaluation of foulants in seawater reverse osmosis (RO) desalination.
