Book excerpt: This report describes a study conducted to investigate the feasibility and effectiveness of injecting an oxidant into the discharge of a hydraulic dredge in order to reduce the depletion of dissolved oxygen in an open-water disposal area. The rapid depletion of dissolved oxygen during disposal operations is caused by chemical oxidation of constituents which are present in a reduced state in the anaerobic sediments. Oxygen may also be consumed by the action of microorganisms; however, this mechanism operates much more slowly and contributes little to the immediate demand for oxygen observed in open-water disposal. Two full-scale field demonstrations were conducted as a part of the study. In the first demonstration pure oxygen was injected into the discharge line of a hydraulic dredge, and, in the second, compressed air was similarly injected. The report describes the equipment and methods used to conduct the demonstrations and the results obtained. The laboratory study section describes the chemical processes responsible for the oxygen depletion in the receiving water during dredging and dredged material disposal operations. The final chapter examines the configuration and cost of injection systems for full-scale dredging operations. alternate oxidants, such as hydrogen peroxide and ozone-enriched oxygen, are also considered.

Book Synopsis Publication Index and Retrieval System by : Herner and Company
Download or read book Publication Index and Retrieval System written by Herner and Company and published by . This book was released on 1980 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 'Publication Index and Retrieval System' is designed to facilitate dissemination of the information contained in the more than 200 reports resulting from the Dredged Material Research Program (DMRP) and to foster operational applications of their findings and conclusions. Information referenced in this document is applicable to project environmental assessments, detailed design, construction, and operation and maintenance as well as evaluation under requirements of regulatory functions programs. Chapter 1 contains abstracts of the DMRP Synthesis Reports, which present summaries of findings for each of the major DMRP objectives with emphasis on the significance and application of the information. Chapters 2-9 contain abstracts for each of the detailed reports; the abstracts are identified under the major DMRP objectives. Chapter 10 contains the abstracts of the reports on the field tests and demonstration projects concerned with the effects of dredged material disposal in open water and the use of dredged material for habitat creation. The abstracts are also indexed as follows: subject, geographic location, agency/organization, and author. (Author).
Book Synopsis Prediction and Control of Dredged Material Dispersion Around Dredging and Open-water Pipeline Disposal Operations by : William D. Barnard
Download or read book Prediction and Control of Dredged Material Dispersion Around Dredging and Open-water Pipeline Disposal Operations written by William D. Barnard and published by . This book was released on 1978 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: In response to the concern over the potential impact of dredged Material dispersion, Task 6C of the Dredged material Research Program was established to develop the capability for predicting the nature, degree, and extent of dredged material dispersion in the vicinity of dredging and open-water pipeline disposal operations. In addition, methods for controlling this dispersion were evaluated. This report synthesizes the results of eight contract research studies and summarizes the available literature concerned with turbidity generation by different types of dredging operations. Water-column turbidity generated by dredging operations is usually restricted to the vicinity of the operation and decreases rapidly with increasing distance from the operation due to settling and horizontal dispersion of the suspended material. Turbidity levels around dredging operations can be reduced by improving existing cutterhead dredging equipment and operational techniques, using watertight buckets, and eliminating hopper dredge overflow or using a submerged overflow system. During open-water pipeline disposal of fine-grained dredged material slurry, 97 to 99 percent of the material descends rapidly to the bottom of the disposal area where it forms a low gradient fluid mud mound. The relative degree of dredged material dispersion at open-water pipeline disposal operations can be best controlled by using different discharge configurations. Water-column turbidity can be all but eliminated by using a submerged diffuser system at the end of the pipeline.
