CHANGES IN ZINC COMBINATIONS IN SEWAGE SLUDGE COMPOSTED WITH AND WITHOUT AN ADDITION OF LIME

Monika Jakubus

 

ABSTRACT



The share of zinc in fractions is not constant and changes under the influence of different factors. Taking it into consideration relevant studies were conducted. Their aim was to explain the influence of time factor and addition of calcium oxide into the sewage sludge on the quantitative changes of zinc in particular chemical fractions of sludge. The experiment was carried out in incubation conditions in time of six months.

Key words: zinc, sewage sludge, incubation, sequential extraction.
