Journal ArticleDOI
Coliform counts of polluted waters: a comparison of media and methods
TL;DR: The pour-plate method with Lactose teepol agar was found to be at least as good as the other techniques, to which it is to be preferred as it is more economical, both in terms of time and materials.
Journal ArticleDOI
The effect of aerated rock filter geometry on the rate of nitrogen removal from facultative pond effluents
TL;DR: There were no differences in the removals of BOD5, TSS and TKN, but the VFARF consistently produced effluents with lower ammonium-N concentrations than the HFARF and higher nitrate-N concentration.
Journal ArticleDOI
Process performance of an experimental deep effluent storage reservoir under different organic loadings in northeast Brazil
Duncan Mara,H. W. Pearson,S. A. Silva,R. de Oliveira,A. L. C. Araujo,R. E. de Oliveira,J. Soares +6 more
TL;DR: In this article, the performance of a pilot-scale effluent storage reservoir was evaluated on the basis of data from two experiments carried out at EXTRABES in northeast Brazil.
Nitrogen removal during summer and winter in a primary facultative WSP pond: preliminary findings from 15N-labelled ammonium tracking techniques
TL;DR: Preliminary findings reveal that a greater proportion of 15N is incorporated into the algal biomass by assimilation and subsequent release as soluble organic nitrogen in summer than in winter and in a much higher proportion in the winter than in summer.
Journal ArticleDOI
The Design and Operation of Waste Stabilization Ponds in Tourist Areas of Mediterranean Europe
TL;DR: In this paper, design guidelines for waste stabilization ponds serving tourist areas in mediterranean Europe are given, with recommendations for per caput wastewater flows and BOD5 contributions, for the selection of design temperatures, and for appropriate equations for the design of anaerobic, facultative and maturation ponds.
