Determination of Sulfonamide Antibiotics in Wastewater by Liquid Chromatography–Tandem Mass Spectrometry

November 8, 2007

Antibiotics are widely used in human and veterinary medicine for the prevention and treatment of bacterial infectious diseases. An important but often disregarded aspect of antibiotic use is the fate of antibiotic residues entering the environment.1 Pharmaceutical industry wastewater, improperly-disposed of unused antibiotics, and non-metabolized antibiotics excreted by humans can all enter the sewer system in low concentrations.

A new treatment successfully removes arsenic, selenium, and mercury from a variety of waste streams

Arsenic, selenium, and mercury occur widely in nature, though at low levels, and are associated with sulfide ores, elemental sulfur, and in crude oil and coal deposits. These metals are used in the manufacture of numerous industrial products, such as semiconductors, fuel cells, photographic processes, agricultural products, preservatives and pharmaceuticals, to name just a few.

We Need Treatment -- Now!

Municipalities, industries find flexibility with mobile providers

Communities expect safe drinking water and clean water to do business. Water treatment plants are designed to provide that commodity but unforeseen situations often arise.

Deep-bed Detox

An established technology is helping remove harmful nutrients from municipal wastewater

As total maximum daily loads (TMDLs) for nutrient discharges have been developed and further revised by federal and state agencies over the years to address water quality concerns, deep-bed denitrification filters have proven to be a highly effective treatment technology used by wastewater plants to meet low total nitrogen (TN) limits. Patented in 1979, the technology of combining denitrification and solids removal in a deep-bed filter process has helped to dramatically improve wastewater quality at treatment plants across the country.

Power plant operators must control pH limits and contaminants in their wastewater streams to meet permit guidelines

When people think of water issues at electric utilities, the first thought that usually comes to mind is production of high-purity water for steam generation. Even though a power plant may not have myriad fluid processes like a refinery or petrochemical facility, water discharge from a steam-generating facility is usually considerable. Chemistry in discharge streams must be carefully controlled to prevent pollution of receiving bodies of water or surrounding land.

pH adjustments can increase the arsenic-removing capacity of adsorptive media

Arsenic (As) removal from drinking water by adsorptive media has been a proven technology for years. In the western and southwestern United States, however, much of the As-tainted groundwater has a pH value that is high enough to significantly reduce the operating capacity of adsorptive media, including the iron-, alumina-, and titanium-based media commercially available to municipalities.

Highlighting UV's Growing Legal Impact

Ultraviolet disinfection's new role in future U.S. drinking water regulations

Ultraviolet (UV) irradiation is a proven disinfection technology that has been used for almost a century. The technology is used to disinfect drinking water (municipal and consumer), wastewater (discharge and water reuse), indoor air, swimming pools, and industrial effluents from the food and beverage industries, cooling towers, fish hatcheries, ballast water, semiconductor fabricators, and pharmaceutical manufacturers.
