Treatment Efficiency of Waste Stabilization Ponds
Journal of the Sanitary Engineering Division, 1972A practical method is given for evaluating the influence of the hydraulics on waste water pond performance. The analysis is based on time-concentration data collected at the outlet for tracer tests performed on prototype ponds and on a hydraulic model.

Boundary conditions for the waste stabilization pond
Water, Air, and Soil Pollution, 1990Two different solutions of the dispersed flow model of the waste stabilization pond based on two different sets of boundary conditions were compared and analyzed statistically. These solutions, used in the prediction of the coliform reduction in the pond, were based on Hulbult's and Danckwerts' sets of boundary conditions.

Stability of kinetic models from waste stabilization ponds
Water Research, 1994Abstract This paper studies the effect of small variations in the value of various parameters on solutions at steady-state in a kinetic model for wastewater stabilization ponds. An analytic method of study is developed together with a function of evaluation whose value provides a measure for stabilizing the results. It was found that the stability of

Algae Removal in Waste Stabilization Ponds
1989Although waste stabilization ponds are generally considered to be suitable in small communities or for the treatment of industrial wastewaters, there are cases where they are considered to be appropriate for big cities also. They are in use at least 39 countries. They may become feasible if land is available at a low cost.

Stratification in Waste Stabilization Ponds I: Effects on Pond Parameters
2012Stratification studies were carried out on the waste stabilization pond system at the University of Nigeria, Nsukka, Nigeria. Analysis of the samples collected with a water column sampler at 5cm and 0.1m apart showed some stratification of temperature, algae, pH, dissolved oxygen, coliform bacteria, chemical oxygen demand and nutrients.
