Design of biogas digester with thermophilic pretreatment for reducing fruits wastes

Introduction

The United States produces more than 70 million tons of organic waste each year. While source reduction and feeding the hungry are necessary priorities for reducing needless food waste, organic wastes are numerous and extend to non-edible sources, including livestock manure, agriculture wastes, waste water, and inedible food wastes.

Pig manure utilization and valorization is an important topic with tightening regulations focused on ecological and safety issues. By itself pig manure is a poor substrate for biogas production because of its excessive nitrogen content relative to available organic carbon. Such substrate is alkaline, and methanogenesis can be suppressed, and so additional substrates with high organic carbon must be added. The most promising is straw, which is available from adjacent biogas plant cultures. However, the abundant lignocellulosic biomass of wheat straw undergoes slow decomposition, and only a fraction of the chemical energy can be converted into biogas; thus economical methods for pretreatment increasing bioavailability are sought. A method was investigated to increase the methane yield in a full-scale plant for co-fermenting pig manure with corn silage, which was the default substrate in the original source reactors. Increased lignocellulosic bioavailability of wheat straw was achieved by combining liquid hot water LHW and steam explosion SE.

Microwave assisted with alkaline MW-A condition was applied in the pretreatment of swine manure, and the effect of the pretreatment on anaerobic treatment and biogas production was evaluated in this study.

In developing countries, biogas energy production is seen as a technology that can provide clean energy in poor regions and reduce pollution caused by animal manure.

Biogas is the mixture of gases produced by the breakdown of organic matter in the absence of oxygen anaerobically , primarily consisting of methane and carbon dioxide. Biogas can be produced from raw materials such as agricultural waste , manure , municipal waste , plant material , sewage , green waste or food waste. Biogas is a renewable energy source. Biogas is produced by anaerobic digestion with methanogen or anaerobic organisms , which digest material inside a closed system, or fermentation of biodegradable materials. Biogas is primarily methane CH 4 and carbon dioxide CO 2 and may have small amounts of hydrogen sulfide H 2 S , moisture and siloxanes. The gases methane , hydrogen , and carbon monoxide CO can be combusted or oxidized with oxygen. This energy release allows biogas to be used as a fuel ; it can be used for any heating purpose, such as cooking.

ГЛАВА 14 Беккер впился глазами в труп. Даже через несколько часов после смерти лицо азиата отливало чуть розоватым загаром. Тело же его было бледно-желтого цвета - кроме крохотного красноватого кровоподтека прямо над сердцем. Скорее всего от искусственного дыхания и массажа сердца, - подумал Беккер.  - Жаль, что бедняге это не помогло. Он принялся рассматривать руки покойного.

Background

 - Меня не интересует ваша колонка. Я из канадского консульства. Я пришел, чтобы убедиться, что с вами все в порядке. Внезапно в гимнастическом зале, превращенном в больничную палату, повисла тишина. Старик внимательно разглядывал подозрительного посетителя. Беккер перешел чуть ли не на шепот: - Я здесь, чтобы узнать, не нужно ли вам чего-нибудь.

    This study aimed to design a biogas digester that works thermophilically and mesophilically and tested its performance to produce biogas and digestate.
