Phosphorus chemistry under aerobic and anaerobic conditions in model two-celled waste stabilization ponds.
(1980)
This study involved a laboratory examination of the phosphorus interactions between the sediment and water as they occur on a diurnal basis in a waste stabilization pond under summer conditions in the southcentral U.S. At ...
Research to establish ecological standards for water resources developments.
(1981)
Three levels of development were identified to represent the environmental condition of the region under consideration. The least disturbed environments are designated as level I areas to which the strictest ecological ...
Design of a general methodology for the evaluation and categorization of an environmental program with special reference to Costa Rica.
(1982)
This research essentially consists of two parts. In the first part, methodological studies were prepared as the basis for the development of the general methodology by which each government or institution can adapt and ...
The selection of best management practices for controlling the non-point source pollution in Oklahoma /
(1984)
Both models start with a soil erosion and water quality packages which use the Universal Soil Loss Equation to predict sediment suspension; the sediment delivery ratio to estimate the actual sediment discharging into the ...
The fate and effects of aqueous film forming foam (AFFF) as it passes through a sand, soil, or activated carbon biofilter with appendices on high performance liquid chromatography and the Beckman Microtox Toxicity Monitor applications to AFFF.
(1982)
The sand biofilters exhibited removals of 90% and greater with a long term loading of 6-8 inches/week and 1000 ppm AFFF (V/V). Sand was found to be a satisfactory biofilter media. The soil biofilters plugged under the same ...
Graph-theoretic approach to the analysis and optimal design of water distribution network.
(1981)
Although emphases have been placed on the use of models developed on hydraulic network, the use of these models are by no means restricted to this area alone. Both models can quite easily be applied to all other networks ...
State-of-the-art of land treatment of corrosive and ignitable waste /
(1985)
This research was conducted to provide state-of-the-art information on land application of ignitable (D001) and corrosive (D002) waste (ICW). Land application is considered a relatively new technology and there is very ...
Computer design of onsite residential lagoons from demographic, hydraulic and hydrologic variables /
(1985)
An investigative field study of onsite residential lagoon systems was conducted to identify important demographic, hydraulic and hydrologic variables affecting components of lagoon water balances. The goal was development ...
A priority setting for urban excreta and/or wastewater disposal program in Indonesia.
(1980)
The objective of this study was to develop an Indonesia urban excreta/wastewater disposal prioritizing model based on government strategies and conditions, as well as characteristics. A priority model for selecting project ...
A reliability study of mechanical equipment at municipal wastewater treatment plants /
(1985)
The failure of equipment has been identified by various researchers to be among the major causes of municipal wastewater treatment plant failures. This research is initiated as a result of the concern with the questions ...
