Monitoring aromatic organics and coagulation optimization
With the increasing awareness about the negative effects of organics within the water and wastewater treatment process and on the health of those using the water, along with increasingly strict water quality regulations, the need for real time organics monitoring is becoming ever more important. One of the most problematic types of organics is aromatic organics. The double bond ring structure of aromatic molecules results in free electrons. These free electrons make aromatic organics react readily ... |

Air emissions impact measurements at a perchloroethene remediation site
As part of an U.S. EPA time critical removal action, an air monitoring system was established to measure real-time impacts of perchloroethene (PCE) on the surrounding areas. The soils and groundwater beneath the site (located in West Fargo, North Dakota) were treated using in situ heating of soil and groundwater, with the produced vapors collected using conventional vapor extraction. In order to control the risks associated with air toxics emissions from the remedial activities, an air pathway ... |
