To cope with the present demand, use of municipal sewage water that consists of domestic liquid waste, as well as industrial effluents, is becoming a common practice. The present study aims to reflect the hazardous effects of sewage water on the environment, with the main focus on heavy ...
for the developing countries with limited cultivated lands, expanding land application of sewage sludge is very essential with the precondition of resolution of pathogen, vector, and heavy metal.Lots of studies have being done on the effects of sewage sludge compost on plants and environment. Some...
The sewage wastewater irrigation applied for a season had no significant effect on a clay soil in terms of the soil physical properties. The pH of the pre-sowing soil was found to be normal (7.6) which is most desirable in agricultural soil. In the field irrigated with sewage water, the ...
