Treatment of sewage sludge with lime and zeolite in relation to its application to agricultural soil
The aim of the present study was to investigate the treatment of sewage sludge produced by municipal wastewater treatment plant. The sludge was amended with quick lime and/or zeolite, using 3% by weight of either lime, zeolite or combination of both.During 6-week stabilization of experimental and control substrates changes in pH and ammonium nitrogen in water extracts were determined. Microbiological examination revealed that counts of faecal coliforms were affected by addition of lime and zeolite, but only up to 3-4 week of stabilization, probably in relation to increased pH. Faecal streptococci were decreased significantly in the substrate amended with zeolite and lime. At the end of the 6-week stabilization period both faecal coliforms and faecal streptococci were below the limit set by the Act No.188/2003.
