Use of NaOH to Control pH for Solubilization of Waste Activated Sludge
Waste activated sludge was collected from the final clarifier of a local municipal wastewater treatment plant. NaOH was used in comparison made of the controlled pH batch experiments with...
A New Strategic Management of Pumping Station in Sewer Systems
Pumping stations are literally the heart of most sewer system operations and sewage treatment plant processes. Current studies show that a small improvement of pump efficiency will offer...
Computer Optimization of a Groundwater Treatment Facility
A computer model has been developed to optimize the operation of a groundwater oil recovery treatment plant. The site consists of 24 pump and treat recovery wells which lead to a treatment...
Impact of Point and Nonpoint Discharges on the Water Quality of a Reach of the Red River of the North
Projected increase of discharge of point and nonpoint-source effluents into rivers, make compliance with water quality standards increasingly difficult and necessitate controlling these...
Coping with EPA's Storm Water Permit for Hazardous Waste Facilities, Industrial Landfills, Wastewater Treatment Plants, and Recyclers
The Environmental Protection Agency (EPA) has released NPDES storm water monitoring data from group applicants. This paper will analyze that data to determine which pollutants are present...
Anaheim State-of-the-Art Water Treatment Plant?Six Years from Conception to Completion
After six years of intensive planning, budgeting, pilot testing, design, and construction, the City of Anaheim, California, has successfully completed the modifications to the 15 mgd Lenain...
Design Guidelines for UV Disinfection Facilities
Current design methods for UV disinfection facilities depend largely on experience with minimum input design variables, such as water UV transmittance and required disinfection efficiency....
Mixing Processes in the Dangava River Estuary
The aim of this report is to present main changes in the hydrology of the Daugava River estuary after its natural water flow became regulated and to present a simple physical model of...
Getting Wet with Metric
Conversion from what is now the American system of units to the SI system of units is a dry subject at best. In the water resources area, however, a rather complete immersion is going...
The Influence of Peak-Regulation of the Three Gorges Power Plant on Navigation
The paper studies the unsteady flow resulted from peak-regulation by daily regulation at both Three Gorges and Gezhouba Power Plants and concludes that the river section between the dam...
An Economy and Risk Analysis of Installed Capacity Expansion at the Three Gorges Power Plant
This paper studies the possibility and economy of peak-regulation operation during flood period at the Three Gorges reservoir, which will at the same time satisfy the requirements for...
Comparison of Near-Field Dilutions Derived from In Situ Measurements and Simulated Dilutions at the Sand Island Sewage Outfall Plume, HI
Near-field dilutions of the Sand Island Treatment Plant (SITP) wastewater plume were derived from salinity measurements made at the sewage outfall between Sept. 25?Oct. 1, 1994, a period...
Groundwater Recharge with Reclaimed Water Another Step Closer to Potable Reuse
California.s water supply is becoming increasingly unreliable, and investments to make water more reliable must be seriously investigated. In this arid region of Southern California, reclaimed...
