Accuracy of Harbeck Diagram for Forced Evaporation
The Harbeck Diagram, a method for estimating the forced evaporation from a cooling pond, gives the fraction of heat load dissipated by evaporation as a function of windspeed and natural...

Density Currents in Sidearms of Cooling Ponds
The design of cooling ponds for dissipating the water heat from steam electric power plants requires the determination of the amount of surface heat loss from the sidearms. The similarly...

Thermal Structure of Cooling Ponds
The vertical stratification of cooling ponds is considered in a quasi-steady framework. Criteria based upon a nondimensional pond number are derived categorizing cooling ponds into the...

Chemical Flocculation in Coal Mine Sediment Ponds

Use of a Scale Model to Improve Pond Circulation

Design Verification for Tropical Oxidation Ponds
In this note the authors will present the results obtained in northeastern Brazil from a series of five pilot scale ponds each having a retention time of 5 days-7 days....

Optimizing Cooling Policy for System Power Plant
A dynamic programminng model has been developed for minimizing the cooling costs of a series of power plants along a tributary discharging into an estuary. Heat production and dissipation...

Cooling Impoundments: Classification and Analysis
Cooling impoundments can have different degrees of internal temperature stratification and of internal flow circulations. Classification criteria are presented that predict the existence...

Cost-Effective Use of Municipal Wastewater Treatment Ponds
Treatment ponds are a cost-effective alternative for municipal wastewater treatment. When compared to other secondary treatment alternatives, ponds are generally the least costly, require...

Strength Characteristics of Bauxite Pozzolana Concrete
Bauxite is currently mined in Ghana on a commercial basis. Beneficiation of the ore is undertaken before it is exported and during the beneficiation process significant amount of the ore...

Optimization of Evaporation Pond Cost
Transient and equilibrium behavior of a prismatic evaporation pond is studied for a given relationship between the evaporation rate and the concentration of the dissolved solids in the...

Wastewater Storage-Simulation of Instream Effects
Simulations using computer models to predict the instream effects of storing wastewater during periods of low streamflow and releasing during periods of high streamflow indicate that instream...

Impermeable Asphaltic Concrete Pond Liner
An impermeable dense hydraulic asphaltic concrete solar evaporation pond liner was developed by the Southern California Edison Co. for the Mohave Generating Station, Clark Co., Nevada....

Liquefaction Considerations for Two Submerged Essential Cooling Ponds

Proposed Design for Oxidation Ponds in Hot Climates
The proper collection, treatment, and disposal of domestic wastewaters is of vital importance in hot climates, particularly in those tropical developing countries where water-related diseases...

Makeup Requirements for Cooling Ponds
This country's demand for electricity has doubled every 10 yr for the last few decades. At present, the rate of growth is even greater. Expert opinion suggests this trend...

Nuclear Power Plant Cooling System Selection
A method of cost-effectiveness was used to identify the best cooling system for a 4,400-MW nuclear power plant. Three alternative cooling systems were analyzed: (1) Recirculating cooling...

Hydraulic Modeling of Shallow Cooling Ponds
The cooling performance of a shallow cooling pond can be determined in a hydraulic model where the residence-time distribution function of a passive tracer is measured at the intake. It...

Biomass Distribution and Kinetics of Baffled Lagoons
The quantity of attached biomass in a model anaerobic waste stabilization pond is affected by light penetration, hydraulic flow pattern, baffle configuration, and the submerged surface...
