Further contributions to nitrogen removal modelling in waste stabilization ponds

Nitrification-denitrification in waste stabilisation ponds: a mechanism for permanent nitrogen removal in maturation ponds.

A pilot-scale primary maturation pond was spiked with (15)N-labelled ammonia ((15)NH(4)Cl) and (15)N-labelled nitrite (Na(15)NO(2)), in order to improve current understanding of the dynamics of inorganic nitrogen transformations and removal in WSP systems. Stable isotope analysis of delta(15)N showed that nitrification could be considered as an intermediate step in WSP, which is masked by simul...

Waste Stabilization Ponds for Waste Water Treatment, Anaerobic Pond

Waste stabilization ponds (WSP) have been used world-wide over the last 50 years for municipal and industrial wastewater. The waste water treatment system has been accepted and used to change the physical, chemical, or biological character of the waste. This article presents the characteristics, parameters, and examples of the waste stabilization ponds all over the world. This work was based on...

Removal of Helminth Parasitic Eggs from Waste Stabilization Ponds at Shimoga

Occurrence of helminthic parasites of human origin in sewage is a major public health concern. Dependent upon the size of the community as well as the prevalence of infection within the community, municipal wastewater can contain varying numbers of Ascaris sp. and other helminthic ova. Infectious diseases caused by fecal pathogens are principal cause of human morbidity worldwide, particularly i...

removal of chromium and cadmium from wastewater in waste stabilization ponds, yazd-iran

background: heavy metals have destructive and irreversible effects on the human, plants and animals. some industries in yazd enter industrial wastewater to municipal wastewater collection system. this can lead to high levels of heavy metals in wastewater and in turn in the wastewater treatment plant effluent.   methods: this study was carried out during four months from december 22, 2009 to may...
