Sulfide ion measurement system

Sulfide ion measurement system

The new SMS-22 Sulfide Ion Measurement System from Electro-Chemical Devices (ECD) features user-selectable automated sequential sampling of sulfide ions in water. H2S can be present in well water, municipal wastewater and wastewater produced by refineries, tanneries, chemical plants, and paper and pulp facilities. The SMS-22 conditions the sample, measures the sulfide, neutralizes the sample, measures the pH and drains and rinses the cell. After measurement, the highly caustic sample pH is reduced to a safe level near pH 8. The ECD SMS-22 is a sequential sampling analyser. Featuring automated sequential sampling, the Model C-22 Analyser controls the sequential sampling with a combination of relays and timers. Sampling times are adjustable from two samples per hour to 10 samples per hour, and the system offers "very low reagent consumption", said the manufacturer. The SMS-22 features 4-20 mA outputs that display the total sulfide as well as the neutralized pH value. The output values are captured in the measurement cycle and displayed until the next measurement cycle. The rugged enclosure provides IP66 protection and is rated NEMA 4X. The base is made of gray hot-molded fiberglass-reinforced polyester and the cover is made of transparent polycarbonate with non-metallic hinges.

BioAir celebrates century of odour control installations

BioAir Solutions has completed its 100th installation at a municipal wastewater treatment plant in Baton Rouge, Louisiana. The company's EcoFilter biotrickling filter technology includes proprietary EcoBase structured synthetic media with engineered flow channels. EcoFilter eliminates odors without using hazardous chemicals and no consumables such as carbon, which has to be landfilled when spent. Installations have been made in the US, Canada, the Caribbean, Australia and the Middle East.

GF mixers save energy

GF mixers save energy

GridBee GF Series electric mixers from Medora Corporation can each displace 30 to 50 horsepower of surface aerator mixing (run-time) in municipal and industrial wastewater applications, including activated sludge system basins, lagoon systems, and water re-use ponds. With the GF Series performing the mixing, the aeration system can be dialed back to just provide the needed DO. At electric rates near $0.10 per kwh, savings per mixer is approximately $750,000 over 25 years.

Track and monitor odours

Kruger, in conjunction with Odotech Inc can provide a real–time odour and air contaminant tracking and monitoring system which operates with the use of electronic noses. OdoWatch 4 is a web-based software that identifies where odour is traveling and the level of its intensity. OdoWatch 4 can track odour, contaminants (H2S, Ammonia, etc), weather conditions and user specified alert points over time. The web-based platform gathers information from odour, contaminant sources and comprehensive weather data that are processed using the CALPUFF dispersion model. A real-time active plume is then generated and overlaid on a map of the area giving users the ability to track odor, contaminant intensity and where it is traveling. The data is collected and stored centrally, and can be used both in real-time and for historical reporting. CALPUFF will allow municipalities to isolate specific operational issues for improvement while lowering costs by reducing the need of odor control chemicals and electricity.

Remote monitoring and control system

Remote monitoring and control system

Liquid phase odor control dosing and optimizing can now be accomplished easier than before with Link2Sitesm wireless-to-web, internet based monitoring and control system, and Vaporlink hydrogen sulfide monitor. Link2Site combines tank, dosing, and H2S data sent automatically from the Vaporlink on the same web page, so dosing rates can be adjusted quickly and easily based on timely information. The system can be configured to alarm on various conditions to help head off odor complaints before they start.
