Environment Analyzers

1. CMES(Continues Emission Monitoring System) or FGMS

CEMS were historically used as a tool to monitor flue gas for oxygen, carbon monoxide and carbon dioxide to provide information for combustion control in industrial settings. They are currently used as a means to comply with air emission standards such as the United States Environmental Protection Agency's (EPA).

The standard CEM system consists of a sample probe, filter, sample line, gas conditioning system, calibration gas system, and a series of gas analyzers which reflect the parameters being monitored.

Measuring Parameters: sulfur dioxide, nitrogen oxides, carbon monoxide, carbon dioxide, hydrogen chloride, airborne particulate matter, mercury, volatile organic compounds, and oxygen. CEM systems can also measure air flow, flue gas opacity and moisture.

2. Waste System Analyzer

Depending on the industry, different demands are made on the quality of water regarding the water influent, water effluent and discharge control. Limits are prescribed by law or defined by industry-specific associations.

Water that is supplied to an existing system, e.g. cooling water circuit, an industrial plant or waste water treatment plant (WWTP) is described as the water influent. Depending on the application, it may be necessary that this water be treated before use.

Water that is derived from a water system is known as the water effluent. Depending on the application, the water matrix may comprise a wide variety of characteristics, one of which being that the process water has a high particle density. To the contrary, process water of a cooling water system is characterized by low particle density, however, it is mixed with chemicals.

Discharge control is the monitoring of the water effluent being released into a river or waste water treatment plant. Local law defines the limits for the effluent in public waters.

Measuring Parameters: pH, Conduct, BOD, COD, TSS, TOC
