TREATED DOMESTIC SEWAGE: KINETICS OF Escherichia coli AND TOTAL COLIFORM INACTIVATION BY OXIDATION WITH HYDROGEN PEROXIDE

Hydrogen peroxide has been used for decades in developed countries as an oxidizing agent in the treatment of water, domestic sewage and industrial effluents. This study evaluated the influence of the concentration of H2O2 and pH on the inactivation of Escherichia coli cells and the disinfection of sewage treated. The results showed that the inactivation rate increased with pH and H2O2. The pres...

Sustainability of Domestic Sewage Sludge Disposal

Activated sludge is now one of the most widely used biological processes for the treatment of wastewaters from medium to large populations. It produces high amounts of sewage sludge that can be managed and perceived in two main ways: as a waste it is discharged in landfill, as a fertilizer it is disposed in agriculture with direct application to soil or subjected to anaerobic digestion and comp...

Wetlands Assimilation of Treated Domestic Sewage for Ecological Restoration and Storm Surge Protection - Public Health Aspects

This paper summarizes the findings of a pre-design feasibility analysis assessing the restoration of significant portions of wetlands in southeast Louisiana by providing nutrients through the introduction of treated municipal wastewater effluent. Wetlands assimilation is a process whereby properly treated and disinfected municipal wastewater treatment plant effluent is used to provide a source ...

Magnesium nutrition of two species of sunflower.

Helianthus annuus L., the common cultivated sunflower, and Helianthus bolanderi Gray subspecies exilis Heiser, a form endemic on serpentine soils, were grown in culture solutions with widely varying Mg levels. For comparable development, H. bolanderi exilis required higher levels of Mg in the solution than H. annuus, both in the range of visual deficiency symptoms and in higher ranges.With 0.5 ...
