Minimizing risks in wastewater reuse: proposed operational principles and guidelines for South Africa
Treated wastewater represents a significant potential source of reclaimed water for some beneficial reuses. However, public concern over the risks/health-related hazards of wastewater reuse has limited the general acceptability of reuse systems in many countries. It is important to manage the operation of recycled water systems in such a way that it will not adversely affect public health and ...

The importance of wastewater treatment in shipbuilding industry
There is a huge amount of wastewater outcome during the ship production and repair processes in shipyards. Especially production processes (blasting, welding, painting, machining and metalworking), repair processes (hull washing) and painting processes (paint removal) create a huge amount of wastewater. In addition to these, open area processes of ship repair and maintenance cause stormwater ...

Determination of public health hazard potential of wastewater reuse in crop production
The potential health hazard due to the utilisation of wastewater for vegetable cultivation in the agricultural fields of Titagarh was assessed. The mean concentrations of Pb, Ni and Cu in the irrigation water and the mean Cd content in soil were above the recommended levels. The mean Pb, Zn, Cd, Cr and Ni contents of the vegetables were found to be above the Indian safety limits. The faecal ...
