Abstract
Analysis of Heavy Metal Fraction Content in Sewage Sludge from Selected Wastewater Treatment Plants
Highlights
According to the Central Statistical Office, the number of municipal wastewater treatment plants in Poland has increased by 125 over the last 10 years
Taking into account the potential benefits from the agricultural use of sewage sludge, the aim of the study was to determine the content of Cu, Zn, Ni, Cd and Pb present in the total forms and fractions of sludge from wastewater treatment plants of population equivalent from about 2000 to more than 100000 and to indicate the statistically significant differences between the content of individual forms of the studied elements
The samples of sewage sludge were dried to constant weight at 105 ̊C before the analysis of the heavy metal content
Summary
According to the Central Statistical Office, the number of municipal wastewater treatment plants in Poland has increased by 125 over the last 10 years. In 2009, there were 3,153 wastewater treatment plants, while in 2019, there were 3,278 plants. The population using wastewater treatment plants in relation to the total population was 64.2% in 2009, 71.5% in 2014 and 74.5% in 2019. The increase in the amount of wastewater treated and the increasing proportion of people using it contribute to the formation of an increasing amount of sewage sludge. In 2009, 563,115 tonnes of sewage sludge was generated, and in 2019 this amount was more than 10,000 tonnes higher [www.bdl.
