Selenium Removal?Can We Afford It?
The process of biologically removing the element selenium from agricultural drainage water is discussed and an economic evaluation of the process is presented. If by-products can be recovered,...
An Overview of Factors Affecting Land Application of Food Processing Wastes
The food processing industry can use slow rate, rapid infiltration or overland flow systems. Slow rate systems are the most common method used for land application. The limiting design...
Winery Wastewater Land Application
Winery wastewater is characterized by low pH, relatively high BOD, and a low nutrient content. Land application using rapid infiltration basins has been practiced successfully at a number...
Management Challenges Affecting Agricultural Reuse of High-Strength Food Processing Wastewaters
Land treatment of high-strength food processing wastewaters is a viable pollution control technology. Due to the high-strength characteristics of these wastewaters, effective site management...
Evaluation of Methods to Determine Peak Period Irrigation Water Requirements
Methods for estimating the peak period irrigation water requirement were evaluated as a component of the review of irrigation facility sizing criteria conducted for the Engineering and...
Review of the Lake Andes-Wagner Project Sizing
Benefit-cost analyses of the proposed U. S. Bureau of Reclamation Lake Andes-Wagner Project have shown the project to be marginally feasible. In an effort to improve the benefit-cost ratio,...
Irrigation with Reclaimed Wastewater?Recent Trends
Land application of municipal wastewater is a well established practice in California. Much of the reclaimed municipal wastewater (57%) in California is used for irrigation of fodder,...
Water Supply Analysis for the Milk River Basin, Montana
The U. S. Bureau of Reclamation's Milk River Irrigation Project provides water for 55,000 ha of irrigation in the Milk River basin of Montana. The project includes an interbasin...
Alternative Formulations for Water Quality Management Models
Various model formulations for water quality management are examined herein, each of which involves a somewhat different approach to the problem of determining optimal treatment levels...
Stochastic Stream Flow Analysis for Hydrograph Controlled Waste Release
A risk based procedure for the design of hydrograph controlled release sewage lagoons is derived. The procedure is based on a stochastic analysis of streamflow events above a given threshold...
