To meet this objective with  co-benefit of bio-energy recovery, anaerobic  technology is a promising technique. However,  anaerobic digestion in particular hydrolysis phase is  a rate-limiting process which requires a long  digestion time to fully stabilize the sludge.  Therefore, a numbers of pretreatments are usually  applied to shorten the digestion time requirement and  to increase the digestion efficiency. In this study,  pretreatments, e.g. ultrasound, chemical and combined  chemical-ultrasound were investigated for their  effective sludge disintegration. Anaerobic digestion  of pretreated sludge, subsequently, was conducted in  order to evaluate the effects of pretreatments on  digester¿s performance. In addition, a comparison of  cost benefit analysis of anaerobic digesters with the  pretreatment options was also presented in this   study.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838379456\"\u003e\u003ch3\u003eAnaerobic Digestibility of Ultrasound, Chemical and Combined Chemical-Ultrasound Pretreated Waste  Activated Sludge\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838379456","offer_id":39482529480797,"sku":"9783838379456","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/da27de26-c790-4094-a588-bcc62559461f.jpg?v=1773383058","url":"https:\/\/shop.autorenwelt.de\/en\/products\/advanced-anaerobic-sludge-treatment-von-bunrith-seng","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
