“…In the liquid phase, the high contents of nitrogen generally with high ammonia percentage, phosphorus, and other macro and micronutrients [11] represent a serious problem for its recovery/disposal. Furthermore, some authors [12] have studied the feasibility to increase the methane productions in AD up to 104% [13] by using the pretreatment of animal manure fibers with aqueous ammonia soaking. Despite this treatment being very interesting, the proposed solution could increase the ammonia content in digestate involving, especially in Italy, additional issues for its recovery on agricultural soils.…”

The proper recovery of resources such as nitrogen and phosphorus present in the manure from intensive livestock farming is essential in order to allow environmental sustainable zootechny especially in densely populated areas where these activities are historically prevalent. The experiences at full-scale established that the ammonia stripping allows recovery from 35% to 50% of nitrogen depending on the type of substrate treated with anaerobic digestion and on the nitrogen content/form in the digestate. This study focuses on the ammonia stripping on digestate derived from anaerobic digestion of livestock manure and corn silage. Two different full-scale plants are studied including a packed column and an air bubble reactor without filling material with the aim to reduce fouling issues due to the content of suspended solids in digestate. The main results suggest that the use of an air bubble reactor could treat digestate with high concentration of suspended solids. A deeper study based on a two-level factorial experiment highlights that the temperature is an important parameter that influences the ammonia removal yields. Thus, a proper management of available thermal energy is very important.

“…Reported values for total and volatile solids per animal are usually 0.5-0.8 and 0.4-0.5 kg d −1 , respectively [29]. Swine manure has a high content of solid particulates that are difficult to digest [24,39]. Straw or saw-dust (as bedding material), other fibers, and lignocellulosic particulates pose a challenge in achieving the full biogas potential.…”

Granular Sludge Bed Processes in Anaerobic Digestion of Particle-Rich Substrates

et al. 2019

Granular sludge bed (GSB) anaerobic digestion (AD) is a well-established method for efficient wastewater treatment, limited, however, by the wastewater particle content. This review is carried out to investigate how and to what extent feed particles influence GSB to evaluate the applicability of GSB to various types of slurries that are abundantly available. Sludge bed microorganisms evidently have mechanisms to retain feed particles for digestion. Disintegration and hydrolysis of such particulates are often the rate-limiting steps in AD. GSB running on particle-rich substrates and factors that affect these processes are stdied especially. Disintegration and hydrolysis models are therefore reviewed. How particles may influence other key processes within GSB is also discussed. Based on this, limitations and strategies for effective digestion of particle-rich substrates in high-rate AD reactors are evaluated. some of the main challenges associated with high-rate anaerobic digestion of particle-rich substrates with special emphasis on manure as a substrate, due to its abundance. Most high-rate AD processes in operation depend on granular sludge to retain sufficient active biomass. Granules are formed by the aggregation of microorganisms that develop into dense masses with sedimentation velocity high enough to avoid washout even under high hydraulic load [7]. It is observed that UASB reactors treating particle-rich manure slurries also accumulates suspended solids from the feed, forming an additional suspended fraction together with the granules [8,9]. The influence of such solids on AD is not understood well, leading some experts to claim that granular sludge bed (GSB) processes may not be appropriate for particle-rich substrates. [10]. It appears, however, that a significant fraction of feed particles can be digested and enhance methane production [11]. This review was undertaken to investigate to what extent and how sludge bed high-rate AD can be used to treat particle-rich substrates. We aim to find more evidence for particle digestion in granular sludge beds, identify process limitations, and find appropriate kinetic models in order to establish design criteria for such processes. There is little directly relevant literature on the topic, limiting this review to mainly indirectly relevant literature. The review covers particle-rich substrates characteristics; particle disintegration and hydrolysis, including models for such; physical characteristics of granular sludge; sludge bed reactor designs and observations of particle effects.

Arıtma çamurlarının stabilizasyonunda kullanılan ve net enerji üretimi ile ön plana çıkan anaerobik çürütme proseslerinin modellenmesi konusunda literatürdeki mevcut çalışmalar proses ve model kompleksliği nedeniyle oldukça sınırlı sayıdadır. Güvenilir dinamik modellenme yaklaşımları; prosesin izlenmesi, proses dinamiğindeki temel mekanizmaların daha iyi anlaşılması ve tanımlaması ile proses davranışının tahmin edilmesine, kontrol algoritmalarının geliştirilmesine ve dizaynın kolaylıkla yapılmasına yönelik önemli bilgiler sunmaktadır. Bu çalışmada; arıtma çamurlarının anaerobik çürütülmesi ile stabilizasyonu ve anaerobik çürütme prosesinin modellenmesinde kullanılan basit substrat karakterizasyon modelleri, ara substrat karakterizasyon modelleri ve ileri düzey substrat karakterizasyon modelleri tanıtılmıştır. Son olarak, Anaerobik Çürütme Modeli (ADM1), ADM1 uygulamaları ve modifikasyonları ve arıtma çamurlarının ADM1 ile modellenmesi konusunda literatürde mevcut çalışmalar detaylı olarak incelenmiştir.
