Aeration Industries won an Environmental Business Journal (EBJ) Business Achievement Award for its successful deployment of the Tri-Oval® Oxidation Ditch wastewater treatment system. It integrates its Aire-O2 Triton process aerator/mixer into the Oxidation Oval format, providing subsurface horizontal mixing at sufficient velocities to prevent solids from settling without need for covers. This permits longer entrainment of the unit’s fine bubble diffused air and allows for deeper ditch designs with smaller footprints. Aeration Industries International Inc., Chaska, MN, 952-448-6789,

With its a multi-beam optical sensor, intelligent microprocessor-based design and self-cleaning technology, the new Triton TR8 Turbidity Analyzer’s sensor electronics constantly adjusts turbidity signal readings versus the reference detector for superior measurement accuracy. A built-in digital filter helps suppress potentially interfering signals while self-monitoring diagnostics assure high reliability. The sensor assembly relies on a long-life near infrared LED light source (880 nm), and the 90° scattered light method in accordance with ISO 7027/EN 27027.

Graver has a new line of advanced stainless steel backwashable precoat septa for reactor water cleanup (RWCU), fuel pool and other specialty applications in nuclear power generation. Aegis PowerGuard® all metal septa are designed to fit original Graver bottom tube sheet installations with OEM supplied nuclear adapter end fittings. This avoids removal of original hardware to minimize internal damage and personnel exposure during replacement. Elements incorporate Poroplate®, an advanced sintered metal design that allows for precise control of porosity (2-200 µm). Graver Technologies LLC, Glasgow, DE, 800-249-1990,

Sierra Monitor’s hydrogen sulfide (H2S) gas sensor module, Model 5100-05-IT, received FM Performance approval for both hazardous location operation and performance. This gives it the first approval for a six-month calibration interval, the longest calibration interval in the industry. Thus, maintenance costs for this unit are half that of other area safety toxic gas sensors. IT Series hazardous gas detectors allow system integrators and instrumentation engineers to interface these sensors into their plant-wide safety and monitoring systems.
