Papers, Discussions, and Closures from ASCE Proceedings and Journal of the Soil Mechanics and Foundations Division
This collection of papers covers a broad range of relevant issues in geotechnical engineering. Topics include capillary phenomena in cohesive soils, final foundation treatment at Hoover...
New Gravity/Pressure Unit Cuts Sludge Dewatering Costs
A new device for dewatering sludges from either industrial or municipal waste treatment plants promises to cut both initial capital and operating costs over more traditional methods such...
Concentric Waste-Treatment Plant Saves Land
An activated-sludge treatment plant in Camden, N.Y. has several innovations: the principal one is the use of concentric tanks�� as distinct from the usual way of having separate, isolated...
Let's Consider Land Treatment, Not Land Disposal
The regulations that control operation and design of land treatment systems are discussed. A solution to control ground water pollution must consider all potential impacts. Pretreatment,...
Wastewater Ozonation: A Process Whose Time Has Come
For many years, ozonation has been a technically viable solution to difficult waste treatment problems. Not until recently, though, has ozonation found growing acceptance as a cost-effective...
Highly Energy Efficient�� Wilton Wastewater Treatment Plant
The municipal wastewater treatment plant for Wilton, Maine, a community of 4,200, received one of two national awards for energy conservation in 1975. The plant includes primary and secondary...
Pilot Plant Program�� Treatment of NYC Water Supply
Many cities with upland reservoirs as their source of water are now finding it necessary to filter the water. Population growth in the upland areas and more stringent standards are the...
Recycling Refuse Into Energy
Some 50% of large cities, 10% of small ones reportedly are talking about recycling their municipal refuse. Several are building facilities or have recently begun operations. This article...
208: A Process for Water Quality Management
The Section 208 program is the key to the continuous management of the nation's water pollution clean-up efforts. In the past, regional approaches to water pollution abatement...
Designing More Reliable Waste Treatment Plants
In the past, many municipal waste treatment plants have not operated reliably. A 1969 Federal Water Pollution Control Administration Study, for instance, showed that 25% of 1500 plants...
Recycling Allows Zero Wastewater Discharge
St. Petersburg, Florida, committed itself to total recycling of its wastewater with zero discharge to its surrounding bays. They plan to accomplish that goal through land disposal techniques....
Tough Pollution Laws Spur Use of Impermeable Liners
Consultants have increasingly been using flexible, synthetic linings for a variety of civil engineering applications. The U.S. Dept. of Agriculture has been using membranes to line irrigation...
Proposed Standards: Land Disposal of Effluents
There are many alternatives to costly advanced waste treatment (AWT) systems. The most attractive of these is land disposal of the sewage effluents from secondary treatment plants. Land...
Nation's Capital Faces Critical Water Problems
Untroubled by any major impoundments and much troubled by polution in its tidal reaches, the Potomac River continues to flow to the sea, while an increasing population depends on this...
Flow Equalization�Plus for Wastewater Treatment Plants
Flow equalization is important in maintaining optimum level performance in chemical water treatment plants. One way to do this is to build storage tanks upstream to regulate flow instead...
What's New in Water Treatment�
The Safe Drinking Water Act recently passed by Congress will have a definite impact on water treatment methods and especially on new standards and the monitoring thereof. Many have felt...
Pipeline Design for Water and Wastewater
Financing and Charges for Wastewater Systems
This joint committee report covers a broad range of relevant issues in financing charges for wastewater systems. Topics include elements and functions of wastewater systems, administrative...
Clean Water for Our Future Environment
Proceedings of the Conference on Clean Water for Our Future Environment, held in Los Angeles, California, March 21-24, 1971. Sponsored by Sanitary Engineering Division of the American...
