Batch and continuous experiments, conducted with two 4\u2010m <jats:sup>3<\/jats:sup> bioreactors using indigenous iron\u2010oxidizing bacteria (20% v\/v of inoculum) with addition of 4.0 g ferrous sulfate heptahydrate per liter of sludge initially acidified to pH 4.0, were sufficient for effective heavy metal (cadmium, copper, manganese, zinc, and lead) removal yields. The average metal removal yields during the FSBL process were as follows: cadmium (69 to 75%), copper (68 to 70%), manganese (72 to 73%), zinc (65 to 66%), and lead (16%). The FSBL process was also found to be effective in removing both fecal and total coliforms (abatement &gt;5 to 6 log units). The nutrients content (nitrogen, phosphorus, and magnesium) were also preserved in decontaminated sludge.<\/jats:p>","DOI":"10.2175\/106143005x73118","type":"journal-article","created":{"date-parts":[[2006,10,6]],"date-time":"2006-10-06T03:19:38Z","timestamp":1160104778000},"page":"872-879","source":"Crossref","is-referenced-by-count":10,"title":["Pilot\u2010Plant Study of Wastewater Sludge Decontamination Using a Ferrous Sulfate Bioleaching Process"],"prefix":"10.1002","volume":"78","author":[{"given":"Guy","family":"Mercier","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patrick","family":"Drogui","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean\u2010Fran\u00e7ois","family":"Blais","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Myriam","family":"Chartier","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2006,8]]},"reference":[{"key":"e_1_2_6_2_1","volume-title":"Standard Methods for the Examination of Water and Wastewater","author":"American Public Health Association; American Water Works Association; Water Environment Federation","year":"1999"},{"key":"e_1_2_6_3_1","author":"Ball J.
