CT5100 Continuous Gas Analyzer CT5100 Continuous Gas Analyzer

Rosemount CT5100 continuous gas analyzer from Emerson Process Management is the world’s only hybrid analyzer to combine Tunable Diode Laser (TDL) and Quantum Cascade Laser (QCL) measurement technologies for process gas analysis and emissions monitoring. The CT5100 is available in two variants: a certified system, housed in a purged and pressurized enclosure for hazardous area installations; and a non-certified system for use in nonhazardous areas. Both can house up to six lasers to measure up to 12 critical component gases and potential pollutants simultaneously within a single system - meeting local, state, national, and international regulatory requirements. The CT5100 is a unique combination of advanced technology, high reliability, and rugged design. Its "laser chirp" technique expands gas analysis in both the near- and mid-infrared range, enhancing process insight, improving overall gas analysis sensitivity and selectivity, removing cross interference, and reducing response time. The laser chirp technique produces sharp, well-defined peaks from high resolution spectroscopy that enable specificity of identified components with minimum interference and without filtration, reference cells, or chemometric manipulations.

SANILEC® 6 Portable Sodium Hypochlorite Generator SANILEC® 6 Portable Sodium Hypochlorite Generator

De Nora Water Technologies’ SANILEC® 6 system generates sodium hypochlorite wherever and whenever disinfection is required. These lightweight, extremely portable systems are designed for use in rural or isolated locations where water purification, waste treatment or surface disinfection is required. SANILEC 6 systems are ideal for use in areas where chemical storage creates a risk or in areas where other disinfectant chemicals are in short supply.

Ultrafiltration Membrane System Ultrafiltration Membrane System

WesTech ultrafiltration offers a unique solution to exceed increasingly stringent water quality standards. Membranes with a small nominal pore size (0.01-0.02 μm) provide an absolute barrier to consistently produce high-quality water by removing microbial and viral pathogens, suspended solids, turbidity, precipitated iron and manganese, and coagulated organic matter.

ABOUT

The removal of contaminants from public drinking water systems in the US is mandated by the Environmental Protection Agency’s (EPA) National Primary Drinking Water Regulations. These are legally enforceable standards that protect public health by limiting the levels of contaminants in drinking water. Similar regulations are managed by agencies worldwide to protect their citizens from drinking water contamination.

There are a plethora of drinking water contaminant removal technologies that public and private water systems use to comply with the EPA’s drinking water regulations. These include reverse osmosis, membrane, nanofiltration, ultrafiltration, chlorine disinfection, UV disinfection and Ozone-based disinfection practices.

The EPA’s list of drinking water contaminants is organized into six types of contaminants and lists each contaminant along with its Maximum Contaminant Level (MCL), some of the potential health effects from long-term exposure above the MCL and the probable source of the drinking water contaminant.

The six types of contaminants are microorganisms, disinfectants, disinfection byproducts, inorganic chemicals, organic chemicals and radionuclides.

Examples of microbiological, organic contaminants are Cryptosporidium and Giardia lamblia. Both of these microorganic pathogens are found in human or animal fecal waste and cause gastrointestinal illness, such as diarrhea and vomiting.

A common disinfectant used in municipal drinking water treatment to disinfect microorganisms is chlorine. The EPA’s primary drinking water regulations require drinking water treatment plants to maintain a maximum disinfectant residual level (MDRL) for chlorine of 4.0 milligrams per liter (mg/L). Some of the detrimental health effects of chlorine above the MCL are eye irritation and stomach discomfort.

Similarly, byproducts from the chlorine-based disinfection methods used by public water systems to remove contaminants can be contaminants in their own right if not removed from the drinking water prior to it being released into the distribution system. Examples of disinfection byproducts include bromate, chlorite and total trihalomethanes (TTHMs). Not removed from drinking water, these disinfection byproducts can increase risk of cancer and cause central nervous system issues.

Chemical contamination of drinking water can be caused by inorganic chemicals such as arsenic, barium lead, mercury and cadmium or organic chemicals such as benzene, dichloroethane and other carbon-derived compounds. These chemicals get into source water through a variety of natural and industrial processes. Arsenic for example is present in source water through the erosion of natural deposits.  Many of the chemical contaminants are derived from industrial wastewater such as discharges from petroleum refineries, steel or pulp mills or the corrosion of asbestos cement water mains or galvanized pipes.

Radium and uranium are examples of radionuclides. Radium 226 and Radium 228 must be removed to a level of 5 picocuries/liter (PCI/L) and Uranium to a level of 30 micrograms/liter (30 ug/L).
