New Clarifiers Help Save History
By using clarifiers to upgrade a waste treatment plant, Camp Dresser & McKee were able to utilize the available space so that an historic building existing within the plant could...
Out of the Mainstream
By treating only part of the wastewater stream, a biological/chemical phosphorus removal system also reduces chemical costs and sludge production. The system consists of two 60 ft dia...
Aeration
A Wastewater Treatment Process
This manual summarizes current aeration practices in wastewater treatment, and includes both theoretical and practical guideline for the design and operation of such unit processes. The...
Water-Quality Ponds ? Are They the Answer?
Water-quality 'wet' ponds have been proposed to treat storm water for the removal of phosphorous in streams tributary to Cherry Creek Reservoir, a major recreational...
Multiple Treatment System for Phosphorus Removal
Detention ponds, wetlands, and infiltration basins have each been shown to reduce constituent loads carried by urban stormwater, including phosphorus. Design recommendations are presented...
Swirl Concentrators Revisited. The American Experience and New German Technology
The Swirl Concentrator is a small, compact, 'no moving parts' solids separation device. Its function is to act as as a static combined sewer overflow (CSO) regulation...
Long-Term Effects of Urban Stormwater on Wetlands
In 1986 scientists and managers associated with local, state, and federal agencies that have wetland protection and stormwater management responsibilities in the region joined to consider...
Ground Water Recharge and Management Under the Small Reclamation Projects Act
The U.S. Bureau of Reclamation through its Small Reclamation Loan Program is providing needed Federal financial and technical assistance to water users in Southern California to help ease...
Aquifer Storage Recovery: A New Water Supply and Ground Water Recharge Alternative
Aquifer Storage Recovery (ASR) involves treated drinking water that is stored underground by injection into a suitable storage zone during those months of the year when available supply...
Tucson Recharge with Existing Potable Water System
In 1987, a study was undertaken to evaluate the potential for using the City of Tucson's existing potable water distribution system and production wells for recharge of treated...
Ground Water Recharge with Sewage Effluent
Recharge systems for soil-aquifer treatment (SAT) of conventionally treated sewage effluent typically remove essentially all suspended solids, biodegradable material (BOD) and microorganisms...
Analysis of Hydraulic Impacts at the Tucson Reclaimed Water Recharge Project
The Tucson Reclaimed Water Recharge site has been implemented with increasingly sophisticated calculation methods as data collection efforts advanced. Initial project scoping utilized...
Reclaimed Water System with Artificial Recharge
Arizona cities must reduce water consumption as a result of the 1980 Arizona Ground Water Management Act. Use of reclaimed water in place of potable water for landscape irrigation and...
Wastewater Recharge: Water Quality and Operations
The Green Valley Wastewater Treatment Facility began operations in its current configuration in 1981. It treats approximately 1 million gallons per day of municipal wastewater, with disposal...
Bacterial Fingerprinting to Trace Source of Coliform Bacteria During Artificial Recharge
This report describes the use of a bacterial 'fingerprint' technique to determine if treated effluent from infiltration beds was the source of coliform bacteria...
Health Effects of Ground Water Recharge
A five year multidisciplinary research project was conducted to evaluate the health significance of using treated wastewater for ground water replenishment. The focus of the study was...
Benefits and Risks of Artificial Recharge of Saline Aquifers
Artificial recharge of saline aquifers by deep well injection of treated effluents is attractive, as it provides a solution to an environmental problem, and possibly creates groundwater...
Artificial Recharge with Imported and Reclaimed Waters in Central and West Coast Basins of Los Angeles County
Since 1952 over 4,000,000 acre-feet of imported water and reclaimed waste water have been purchased to recharge the ground waters of the Central and West Coast Basins of Los Angeles County....
Artificial Recharge in Finland
There are four reasons for artificial recharge of ground water in Finland: 1. The replenishment of aquifers by lake water. 2. To use aquifers as part of surface water treatment process....
The Tunisian Experience in Ground Water Artificial Recharge by Treated Wastewater
In Tunisia, because the water resources are limited, the reuse of treated wastewater in agriculture becomes a necessity. The artificial ground water recharge is one of alternative forms...
