Comparison of different wastewater treatments for removal of selected endocrine-disruptors from paper mill wastewaters
Magnesium and calcium contents in water samples and wastewater sludge specimens collected in the upper silesian region
Magnesium and calcium ion concentrations were determined in drinking water and wastewater sludge samples coming from the industrialized Upper Silesian Region and ( for comparative purposes ) from different non- industrialized bockground areas.Mg2+ Ca2+ concentrations in water samples were measured by spectrophotometry ( Mg2+ concentration in the reaction with the Mann and Yoe agent,and Ca2+ concentration in reaction with metalphthalein). In wastewater sludge, Mg2+ and Ca2+ content was determined by AAS.The concentration of Mg2+ in the water samples was generally below the concentrations of both the ions were noticeably high,thus making the investgated sludge snitable for agricultural uses,provided that the concentration of heavy metals is within the range of permissible values
