Automated Critical Link Analysis (CLA) using Network Modeling
Untitled Document One of the key words being used in the water and wastewater industry globally is ‘risk' . Asset managers now plan the most cost-effective approaches to managing their network by determining the risk grade for each asset. Risk is the product of two factors – the impact of failure, multiplied by the probability of failure. However, measuring these two factors is a time-consuming process if approached manually, and utilities rarely have the level of engineerin...
CMOM Workshop, Austin, Texas - Capacity Assurance by Metering and Modeling
Untitled Document Why is flow metering important? There are two fundamental reasons for the importance of flow metering and measurement. First, information, either for direct management needs - “You can't manage what you can't measure” - or indirectly for further analysis, including modeling. The second is its role in operational control. SCADA measurement for example is often directly linked to system controls, tracking trends and changes in system characteristics, just like a blood...

Introduction: Soil washing is a water-based process for scrubbing soils ex situ to remove contaminants. The process removes contaminants from soils in one of two ways: By dissolving or suspending them in the wash solution (which can be sustained by chemical manipulation of pH for a period of time). By concentrating them into a smaller volume of soil through particle size separation, gravity separation, and attrition scrubbing (similar to those techniques used in sand and gravel operations). Soil washing...

Common Treatment Technologies for Halogenated SVOCs in Soil, Sediment, and Sludge
Common treatment technologies for halogenated SVOCs in soil, sediment, and sludge include biodegradation, dehalogenation, incineration, and excavation with off-site disposal. All types of biodegradation, both in situ or ex situ, can be considered to remediate soils: in situ bioremediation, bioventing, composting, controlled solid phase, or landfarming. Slurry phase biological treatment is also applicable but is less widely used. Treatability studies should be conducted to evaluate design parameters, such as...
Common Treatment Technologies for Nonhalogenated SVOCs in Ground Water, Surface Water, and Leachate
It may be necessary to know other subsurface information to remediate nonhalogenated semivolatile organics in water. Treatability studies may be required to determine the contaminant biodegradability for any biodegradation technologies. Treatability studies are also necessary to ensure that the contaminated ground water can be treated effectively at the design flow. A subsurface geologic characterization would be particularly useful to any isolation or stabilization technologies. Ground water models are also...
Common Treatment Train for Fuels
A treatment train is the combination of different treatment technologies. A system diagram of a common treatment train for fuels is illustrated below. The fuel contaminated soil is first treated using a soil washing process. Water is injected at the up stream side of the contaminated site. Surfactant or other additives may be added to enhance the soil washing effect. Contaminated water is pulled out through extraction wells installed at the down stream side for further treatment. An in situ bioremediation process...
Common Treatment Train for Halogenated VOCs
In general, no single technology can remediate an entire site. Several treatment technologies are usually combined at a single site to form what is known as a treatment train. A system diagram of a common treatment train for halogenated VOCs is illustrated below. A ground water pumping system is used to pull contaminated water from the subsurface. The VOC contaminated water is pumped to a liquid phase granulated activated carbon (GAC) adsorption system. The GAC system removes VOCs in the water and the effluent is...
Plume distortion and apparent attenuation due to concentration averaging in monitoring wells
