Wastewater Treatment

by Babcock & Wilcox MEGTEC     based in De Pere, WISCONSIN (USA)

Many industrial and pharmaceutical processes generate wastewater with volatile contaminants that increase the COD and BOD to a point where discharging to municipal wastewater is very costly or not an option. These contaminants can be removed from the water by distillation, substantially lowering the disposal cost, and, in many cases, the removed components can be further purified and reused in the process. MEGTEC offers the following solutions to remove the volatile contaminants and make wastewater suitable for discharge to most municipal wastewater treatment plants: Stripping columns using direct steam or a reboiler Distillation columns using indirect steam heat sources Our technologies have been applied to a range of processes including wastewater treatment from industries such as Pharmaceutical, Semiconductor, Chemical and Petrochemical.

Measurement of diacetyl in ambient air to monitor workplace exposure limits.

by MOCON - Baseline     based in Lyons, COLORADO (USA)

The Series 8900 Diacetyl Analyzer provides direct measurement of Diacetyl in ambient air. This instrument is utilized for environmental monitoring and to monitor workplace exposure limits. The Series 8900 Analyzer for Diacetyl employs a photoionization detector (PID) as the sensing element. A dual column configuration with timed backflush to vent is used to strip off moisture and heavier hydrocarbons. A pre-cut column is used in series with the analytical column. At sample injection a fixed volume of sample is carried to the pre-cut column. Backflush is timed so that only the Diacetyl and other similar components are eluted to the analytical column. Contaminants on the pre-cut column are backflushed to vent. The Diacetyl is separated from potentially interfering components on the analytical column and elute to the detector for analysis.

Measurement of formaldehyde in ambient air for monitoring workplace exposure limits

by MOCON - Baseline     based in Lyons, COLORADO (USA)

The Series 8900 Formaldehyde Analyzer provides direct measurement of Formaldehyde in ambient air. This instrument is utilized in industrial plants to monitor workplace exposure limits. The Series 8900 Formaldehyde Analyzer employs a flame ionization detector (FID) as the sensing element. A dual column configuration with timed backflush to vent is used to strip off moisture and heavier hydrocarbons. A pre-cut column is used in series with the analytical column. At sample injection a fixed volume of sample is carried to the pre-cut column. Backflush is timed so that only the Formaldehyde and other similar components are eluted to the analytical column. Contaminants on the pre-cut column are backflushed to vent. Formaldehyde is separated from potentially interfering components on the analytical column and elute to the detector for analysis.
