Urban storm runoff and combined sewer overflow pollution, Sacramento, California by Envirogenics Company( Book )

3 editions published in 1971 in English and held by 119 WorldCat member libraries worldwide

Necessary data are not available in most areas to determine or predict distributions of storm water runoff and combined sewage flows and pollutant concentrations. To alleviate this problem, a procedure was developed to permit rapid, economical, and accurate assessments of system performance based on 3 different and important water quality criteria. The first criterion establishes an absolute maximum pollutant concentration which cannot be exceeded. The second criterion establishes an acceptable distribution of pollutant concentration by specifying the greatest frequency of occurrence for a particular concentration value. The third criterion establishes the maximum acceptable excession frequency for a particular pollutant frequency. A computer model was then used with a modified rational runoff method to perform preliminary design tasks and weigh alternatives to the designs. Then the least costly system developed for the Sacramento, California area as an example
Reverse osmosis renovation of primary sewage by D.L Feuerstein( Book )

3 editions published in 1971 in English and held by 104 WorldCat member libraries worldwide

A reverse osmosis pilot plant was operated on both primary and secondary effluent and the results compared. Data indicated that high axial feedwater velocities were necessary to prevent membrane fouling. The main substances causing fouling were suspended particulates, inorganic salt precipitates, and dissolved organic matter, as well as some other substances which are unknown at this time. Suspended particulates were flocculated, settled, and filtered out of the wastes, inorganic salt precipitation was controlled by pH adjustment, except in the presence of calcium sulfate, and dissolved organic matter can be removed by biological treatment. Cleansing the membrane with an enzyme-active laundry pre-soak formulation proved beneficial for both wastes
A feasibility analysis of incinerator systems for restoration of oil contaminated beaches by R. M Roberts( Book )

1 edition published in 1970 in English and held by 97 WorldCat member libraries worldwide

The feasibility of employing a combustion process for restoring oil contaminated beaches was investigated. Beach access problems and the handling characteristics of shore materials limited the potential application to recreational (sand) sites. Thermodynamic arguments required that a system design be adopted in which the contaminated sand would undergo combustive processing in a confined arrangement. The design selected, from those analyzed, proved to be a three-effect combustor based on the rotary kiln principle. Provided that the sand to be cleaned is carefully enough collected to furnish a reasonable (>̲6%) oil content and is moved away from the surf and drained to an acceptable moisture level (<̲6%), basic processing costs would be highly attractive. In comparison with uncontaminated sand, the cleaned product exhibits only a slightly greyish hue

In-sewer fixed screening of combined sewer overflows by D. L Feuerstein( Book )

1 edition published in 1970 in English and held by 72 WorldCat member libraries worldwide

Field sampling and measuring were conducted in conjunction with laboratory investigations on the characterization of combined sewage and the effects of solids removal on chlorination practices. Sixty combined sewage bulk samples and 60 combined sewage screenings samples retained on screens of 0.125-, 0.25-, 0.5-, and 1.0 in. aperture were analyzed and evaluated. Removals of deoxygenating materials, oils and greases, and bacteria by fixed screens placed in combined sewers were marginal. Reductions in chlorine requirements as a result of prior solids removal by fixed screening appear small. Screens with aperture sizes ranging from 0.0164 to 1.0 in. appear to have very little effect on bacterial concentrations

Water quality criteria data book( Book )

1 edition published in 1972 in English and held by 3 WorldCat member libraries worldwide

A new technique has been developed for establishing firm criteria for health risks associated with recreational water bodies. The basis of the method is a mathematical treatment of medical dose-response data in conjunction with the probability of exposure over a period of time to a given level of the potentially harmful factor, such that a quantitative risk can be assigned to the recreational activity. Once a public health jurisdiction has established an acceptable level of risk, curves produced by electronic data processing equipment can be used to ascertain whether a particular water should be open to the public
