Trussell Technologies’ Pasadena fabrication facility brings a unique ability to construct custom pilot equipment, modify commercially available test equipment, and develop specialized engineering tools for our pilot- and bench-scale testing. We have constructed ozone pilot contactors, our own collimated beams for UV dosing studies, specialized water quality monitoring skids, a bench-scale ozone apparatus, and groundwater desalting process skids complete with tray aeration/greensand pretreatment and post-treatment boron removal, disinfection and stabilization. Our fabrication facility gives our firm a unique ability to deliver a customized solution to achieve project-specific objectives with the proper equipment to operate and evaluate the unit processes.
Groundwater Treatment Skid
Currently in construction at our fabrication facility is a small-scale groundwater treatment skid (4,000 gpd) designed to treat water for potable use from a brackish well (located in a rural site within the foothills of Santa Paula, CA). The overall treatment process incorporates tray aeration, greensand filtration, reverse osmosis, ion exchange, and chlorination. The system is currently under development and will be built in-house and installed by the end of 2012.
Air Powered Injector
Shown here is a demonstration of equipment that Trussell Tech developed to perform ultra-short duration tracer studies for characterizing hydraulic properties of UV reactors used in Advanced Oxidative Processes (AOP). This type of tracer study is possible by a high-speed conductivity transmitter and air-powered injector that are electronically controlled and synchronized.
Specialized Tracer Equipment
Shown here is a demonstration of equipment that Trussell Tech developed to perform ultra-short duration tracer studies for characterizing hydraulic properties of UV reactors in full advanced treatment (FAT) trains have contact times on the order of seconds. The specialized tracer equipment made it possible to reliably determine the hydraulic characteristics of these specialized reactors.
MFI Measuring Device
Due to operational issues with commercially available equipment, we developed our own modified fouling index (MFI) measuring device. It proved to be easier to operate and maintained a more consistent pressure. This is critical to obtain precise and accurate MFI measurements.
Shown is a rack that Trussell Tech constructed with three online ammonia analyzers and PLC data logger. It was used as part of a year-long study where ammonia levels were recorded at different nitrifying wastewater treatment facilities across California in an effort to determine nitrification reliability and to study the performance of state-of-the-art, online ammonia analyzers.
