Details

Hydrogen peroxide (H2O2) is an extremely strong oxidizer widely used in bleaching applications in the paper industry. It has also been used in a variety of applications including disinfection, odor control, oxygenation, and cyanide oxidation. It is frequently used in wastewater collection systems to remove hydrogen sulfide that destroys concrete pipes and manhole structures. Peroxide applications in aqueous systems, like most chemical treatment processes, function most efficiently with accurate measurement and control.

ATI’s Model Q46/84 Hydrogen Peroxide Monitor is designed to continuously measure the concentration of H2O2 in aqueous systems. Using a direct peroxide sensor, the unit responds rapidly to changes in concentration, enabling operators to control chemical feed to maintain specific targets. With both digital and analog communications available, the Q46 is adaptable to a wide variety of peroxide monitoring applications.

Hydrogen Peroxide sensors are amperometric devices isolated from the water by a peroxide permeable membrane. As peroxide diffuses through this membrane, it comes in contact with an active electrode and is oxidized on the surface. The net effect is that the sensor generates a current proportional to H2O2 concentration. An integral RTD in the sensor provides for automatic temperature compensation, allowing the sensor to operate accurately over a range of 0-50°C.

Peroxide sensors are capable of operating over a fairly broad concentration range, from a low range of 0-2 PPM up to a high range of 0-200 PPM. Systems will operate with good sensitivity down to 0.05 PPM and respond to changes in concentration within about 60 seconds, making them useful for automatic control.

Hydrogen Peroxide sensors require a steady flow of sample across the membrane at the tip of the sensing assembly.  ATI offers options for flowcells, including the standard constant-head overflow system, and a sealed flowcell for pressures up to 50 PSI. For simplicity of installation, complete flow control assemblies are available. Panel assemblies are available with or without a flow switch and can greatly reduce installation time.

Monitoring and Tracking Ocean Microbes with LRAUVs

In March and April of 2018, researchers from the University of Hawai'i at Mānoa (UH Mānoa) and the Monterey Bay Aquarium Research Institute (MBARI) deployed a small fleet of long-range autonomous underwater vehicles (LRAUVs) in the waters of the Pacific near Hawaii. These LRAUVs automatically collect and archive samples of seawater, enabling scientists to study and track ocean microbes with a level of detail that is unprecedented. Chasing eddies The team who undertook the expedition on the research vessel Falkor was hoping to survey and track Mesoscale eddies within the North Pacific Subtropical Gyre (NPSG) using a suite of oceanographic instruments.

Toxic Chemicals in Plastic Pollution Littering Freshwater Habitats

When we consider the glut of plastic rapidly accumulating all over the world , it's easy to see the problem of pollution and disposal of substances that don't biodegrade. However, it's not always as apparent to us that plastic pollution also means a growing number of toxic chemicals in the environment, many of which can be harmful to ecosystems. Plastic polymers and the products made from them are wildly diverse as to chemical properties, composition, and range of potential applications, although most plastics are made from petrochemicals. Throughout the very long lifespan of any given plastic product, the material may release various hazardous substances .

CO2 Cacophony in Acidified Oceans Will Confuse Baby Fish

Ocean acidification is a simple process that has complex effects. Increasingly acidic ocean waters create a cascading series of changes and problems for marine life, as each response to the changing conditions prompts other crises. Recent research from the University of Adelaide reveals a novel problem: baby fish will have more trouble finding and reaching shelter in the acidified oceans of our shared future, placing populations of various fish at risk. Despite how they may seem to humans, oceans are not silent worlds. They are filled with all sorts of noise, from fish sounds and whale vocalizations to the sounds produced by different kinds of habitats.
