Anaerobic co-digestion (AcoD) is proved as an effective approach to solving a bottleneck problem of the low biogas yield in agricultural biomass waste treatment with anaerobic digestion (AD) technology. The present study investigated the effect of C/N radio, organic loading rate (OLR) and total soli

However, the bioreactor effluents had higher concentrations of humic substances and ammonia than the feedstocks. Moreover, AD had a different influence on the content of amino acid in the pig manure compared to the dairy manure. The results obtained indicated that the key inhibitory factors of ADS might be attributed to ammonia and humic

Partial nitrification-anaerobic ammonium oxidation (PN-anammox) was started up within 40 days by bioaugmentation and aeration control, and its performance in the treatment of anaerobic digestate of pig manure (ADPM) was evaluated. Inhibitors in ADPM decreased the nitrogen removal rate (NRR) by 0.24 g N/L/d.

2020/2/4/ · Also, pig manure (PM) is used as a support in the biological process, being the primary nitrogen source, allowing to reach the adequate C/N ratio for the planned tests . Effect of substrate concentration on hydrogen production by photo-fermentation in the pilot-scale baffled bioreactor. Bioresour Technol 247:1173–1176.

This study aims to analyze the importance of UASB digester to treat pig manure. Swine production has an important role on the economic development of Brazil. However, the increase in production is causing serious environmental problems, due to the large volume of solid waste generated by the activity. The development of waste treatment that

2019/5/15/ · The response of two experimental, continuously stirred tank reactors under mesophilic condition (fed with pig manure) was investigated to analyze the perturbation of organic and hydraulic overloading, and low-temperature shock. The pH was stably maintained in the range of 7.2-7.7, regardless of the presence of most simulated

2022/11/22/ · Duckweed (Lemna) is a possible solution for the treatment of aqueous waste streams and the simultaneous provision of protein-rich biomass. Nitrification-Denitrification effluent (NDNE) from pig manure treatment has been previously used as a growing medium for duckweed. This study investigated the use of a continuous duckweed

2022/10/1/ · To investigate the effect of intermittent aeration on oxygen dynamics, organic matter degradation and main gas emissions, a lab-scale pig manure composting experiment was conducted with intermittent aeration (I_A, 30-min on and 30-min off) and continuous aeration (C_A).Although aeration volume and oxygen supply of I_A was only

2024/2/10/ · Table 1. Experimental design outlining treatments with removal of 5 l cell suspension and addition of Na-acetate (Bioreactor 1) or dilute pig manure (Bioreactor 2) over the course of the experiment for Chlorella sorokiniana MACC-728 grown in 100 l bioreactors in a greenhouse in November 2020. Nitrogen concentrations in the Tamiya

2013/5/31/ · A low-temperature (25°C) anaerobic eight-compartment (PF01 to PF08) cascade reactor simulating a plug-flow reactor (PFR) treating pig manure was monitored for a year. The bioreactor was fed at an average loading rate of 2.4±0.2 g of total chemical oxygen demand (TCOD) per litre of reactor per day for a theoretical hydraulic retention

2023/1/1/ · 1. Introduction. China is a large agricultural country that produces a large amount of livestock manure and crop straw every year. According to the National Bureau of Statistics of the People's Republic of China (2020), 91.4 million cattle produced 3.8 × 10 8 tons of manure in 2019 and about 1.0 × 10 9 tons of crop straw per year in China (Jiang

2023/8/27/ · In a recent study, it was reported that the production of biogas was increased significantly up to 441.3 L/·kg vs. when pig fat is added as supplement to the bioreactor having poultry manure . Similarly, pig manure was supplied with spent coffee grounds, resulting in enhanced methane production [ 86 ].

2021/1/7/ · It also provides idea about optimization of biogas generation from biochemical reaction in a lab-scale bioreactor. 3 Materials and . 3.1 Experimental setup. Muzenda E (2015) Methane production from anaerobic co-digestion of cow dung, chicken manure, pig manure and sewage waste. Proceding of World Congress on …

pig manure with no modification that simulated a typical storage pit. 132 Oligolysis: an electrolytic process in which two iron bar electrodeswereplaced in the liquid manure 30 cm apart in the bioreactor. A DC current(12 V, 0.5 Amp) was passed through the slurry using a automobile battery charger. The three bioreactors were electrically
