  • Taking military barracks wastewater treatment as an example, this paper presents a new concept design of a modified DEWATS system with both the horizontal subsurface constructed wetland and aquatic plants pond. Results show that this process in treating the military barracks area wastewater have many advantages such as low operation cost, simple operation and maintenance, and the effluent could meet "the urban wastewater treatment plant pollutant discharge standard" for first level Class A.

  • This volume covers the technologies that are applied to the treatment and purification of water. Those who are generally familiar with this field will immediately embrace the subject as a treatise on solid-liquid separations. However, the subject is much broader, in that the technologies discussed are not just restricted to pollution control hardware that rely only upon physical methods of treating and purifymg wastewaters.

  • To properly operate a waterworks or wastewater treatment plant and to pass the examination for a waterworks/wastewater operator’s license, it is necessary to know how to perform certain calculations. In reality, most of the calculations that operators at the lower level of licensure need to know how to perform are not difÞcult, but all operators need a basic understanding of arithmetic and problem-solving techniques to be able to solve the problems they typically encounter.

  • The use of aeration in the wastewater treatment field has been in existence for over a century. Each of the authors has been involved with the theory and application of aeration systems for a little less than half a century. It was a daunting task to put together what we considered the important principles underlying the mechanisms involved in aeration and show how they are applied in practical applications.

  • On average, one ton of hazardous waste per person is generated annually by industries in the United States. Before the Resource Conservation and Recovery Act of 1984, hazardous wastes were improperly disposed of into the environment without any regulation. As a result, remediation of these contaminated sites and management of the ongoing hazardous waste sources are two major tasks to be achieved by treatment technologies.

  • Organic carbon concentrations can be reduced by enhanced coagulation, granular activated carbon or membrane filtration, but this fact can also lead to increased in brominated THMs (Black et al, 1996.). A combination of coagulation, ozonation, and biofiltration can effectively reduce trihalomethane and haloacetic acid formation potential (Chaiket et al, 2002.). Natural organic matter (NOM), the main precursor of DBPs, can also be removed by media filters coated with iron oxide

  • Before any water or wastewater can be treated, it must first be characterized. Thus, characterization needs to be addressed. Waters and wastewaters may be characterized according to their quantities and according to their constituent physical, chemical, and microbiological characteristics. Therefore, Part I is composed of two chapters: “Quantity of Water and Wastewater,” and “Constituents of Water and Wastewater.”
