Two types of electron donor were tested: lactate and slow release electron donors such as carbohydrate based polymers and lignocellulosic biowastes. Biological sulphate reduction was evaluated in different bioreactor configurations: the inverse fluidized bed, sequencing batch and batch reactors. The reactors were tested under steady-state, high-rate and transient-state feeding conditions of electron donor and acceptor, respectively. The results showed that the inverse fluidized bed reactor configuration is robust and resilient to transient and high-rate feeding conditions at a hydraulic retention time as low as 0.125 d. The biological sulphate reduction was limited by the COD: sulphate ratio ( 82% either using carbohydrate based polymers or lignocellulosic bio-wastes, in batch bioreactors. The biological sulphate reduction was limited by the hydrolysis-fermentation rate and by the complexity of the slow release electron donors.\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Luis Reyes-Alvarado\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1138343315\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781138343313\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e CRC Press\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 09\/12\/2018\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 234\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 1.15lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.40h x 6.70w x 0.70d","brand":"Luis Reyes-Alvarado","offers":[{"title":"Paperback","offer_id":48113275306239,"sku":"9781138343313","price":84.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_85a50492-bb98-4b77-b371-950bc7a0c68c.jpg?v=1769614026","url":"https:\/\/www.whiterainbookhouse.com\/products\/optimization-of-the-electron-donor-luis-reyes-alvarado-9781138343313","provider":"WR Book House","version":"1.0","type":"link"}
