Evaluation of SSET: The Sewer Scanner and Evaluation Technology by Civil Engineering Research Foundation Pdf

Prepared by CEITEC, a CERF innovation center serving the engineering and construction industries. This report describes an evaluation of Sewer Scanner and Evaluation Technology (SSET) designed to determine the basic capabilities and limitations of SSET for use as a technicallly viable technology for inspecting sewer pipes. The evaluation focused on the performance and in-service demonstration of SSET. The technology involves digital scanning to obtain a flat, "unfolded" image of the pipeline's interior. This evaluation includes field demonstrations performed at 13 municipal public works agencies throughout North America. Subsequent to this evaluation, SSET was modified to include a fisheye lens camera and fiber optic gyroscope, which replaced the rotating mechanical scanner and mechanical gyroscope. The evaluation confirmed the operability of SSET and its viability in data presentation. A degree of enhancement was recognized with additional features, most notably the ability to produce a digital report of the sewer pipe, to identify vertical deflection in pipes, and to deliver easily comprehensible and manageable results. The evaluation also revealed that SSET cannot reproduce all the features typically available from closed-circuit television (CCTV) inspection. Such features include the ability to clearly see corrosion, infiltration rates, and ovality. The limitations in applicability were determined and an economic comparison of SSET and CCTV is provided.

Environmental Technology Verification Report for Installation of Silt Fence Using the Tommy Static Slicing Method by Environmental Technology Evaluation Center (U.S.) Pdf

Prepared by the Environmental Technology Evaluation Center (EvTEC), a CERF Innovation Center. This verification report describes a field evaluation of the installation of a silt fence using the Tommy? Silt Fence Static Slicing Method and compares this method to traditional trenching methods. The slicing method has been used extensively over the past few years but has not undergone a true field application test by a third party. State Departments of Transportation and federal, state, and local environmental regulatory agencies have expressed a desire and, in some cases, a need, for baseline environmental data providing a general picture of performance and feasibility of the Tommy Slicing Method for silt fence installation and erosion control.

Environmental Technical Verification Report for Ammonia Recovery Process by Environmental Technology Evaluation Center (U.S.) Pdf

Prepared by the Environmental Technology Evaluation Center (EvTEC), a CERF Service Center. This report describes the nature and scope of an environmental evaluation of ThermoEnergy Corporation's Ammonia Recovery Process (ARP) System, a method for recycling ammonia in wastewater. The data in this report were collected over a three-month pilot study.ØTests found that the ARP system is capable of removing 75?99% of the ammonia in the waste stream in a domestic wastewater treatment plant. The ARP System uses a series of absorption, evaporation, and crystallization steps to convert ammonia in wastewater into a commercial fertilizer, ammonium sulfate. The evaluation results clearly indicate that the ARP process is capable of achieving significant ammonia reduction under a range of environmental conditions

Evaluation of Wet-weather Pavement Markings by Anonim Pdf

This report details the first year of a two-year project. During the first year the emphasis was on determining the wet-night visibility of various pavement marking systems under a variety of realistic rainfall levels. The researchers performed a literature review. They analyzed 20 years of Texas rainfall data to determine the most appropriate rainfall levels to use as design criteria for a rain tunnel. Using a low, medium, and high rainfall rate (0.28, 0.52, and 0.87 in. per hour, respectively), a 1600 ft long rain tunnel was designed and built at Texas A & M University's Riverside Campus. Experimental subjects drove through the rain tunnel and looked for pavement markings simulating skip lines. The researchers rotated pavement marking samples at different locations before each trial. The detection distance was recorded when the subject located the pavement marking sample. The data were analyzed in four main sections: waterborne paints, thermoplastics, tapes, and exotic materials. The analysis also included investigations into the wet-night visibility of rumble stripes, as well as wider lines. The measured dry and wet retroreflectivity measurements were analyzed, and the predictive capabilities of the wet retroreflectivity measurements were evaluated with respect to the wet-night detection distance of the markings.
