2021/11/15/ · Likewise, Saad et al. tested the effects of using aeration tank sludge, return-activated sludge, and palm oil mill effluent sludge as microbial sources on the anaerobic co-digestion of food waste and CM; they found that the highest biogas production (120.97 N mL/g COD) was obtained when aeration tank sludge was used as the
2021/2/1/ · The animal manure utilization chain includes two stages or four stages, depending on the manure utilization mode and manure commercial value, as shown in Fig. 1.The solid manure produced by poultry or sheep has higher nutrient concentration and is valuable for processing, transportation, and utilization (Sharara et al., 2018).The fertilizer
Due to the large quantity and wide range of solid wastes of the biomass, and the dual characteristics of pollution and resource utilization, the energy utilization of anaerobic fermentation can promote its pollution control, so the mixed fermentation technology of solid wastes of agricultural biomass was studied. Corn straw, pig manure, and kitchen waste
2015/11/1/ · This paper explores optimal tank size for domestic rainwater harvesting systems in Asian tropical climates. A total of 128 locations in Vietnam covering three
2017/5/1/ · The acidogenic phase completely stirred tank reactor was operated up to an OLR of 23 kg COD/m3 d with a HRT of 0.5 days whereas the methanogenic-phase upflow anaerobic filter was loaded up to an
2023/10/1/ · The main types of AM accounted for the following percentages: 5.61% pig manure, 13.24% sheep manure, 49.21% cattle manure, and 8.34% chicken manure. Manure emissions from different AF are influenced by factors such as the number of times the animal ingests food, the manure excretion system, and the ingestion time.
2023/11/21/ · Anaerobic co-digestion (AcoD) of animal waste and agro-industrial by-products has been widely studied and employed to increase biogas production potential and enhance process stability. This study evaluated the AcoD of cattle manure (CM) and brewer’s residual yeast (RY) in semi-continuous biodigesters, focusing on energy
2021/11/12/ · Animals’ manure contains 70–90% organic matter, nitrogen, phosphorus and may causes pollutants without proper disposal. For example, each chicken has a daily excreta discharge of 52–81 g with 50.5% water content, which contains 25.5% of organic matter, 1.63% of nitrogen, and 1.54% of phosphorus [].The manure potentially has a high
2023/4/17/ · The Importance of Conducting a Space Utilization Study. According to commercial real estate firm CBRE, utilization is the top occupancy metric among its clients, with 74% using it for planning and development. Renting office space is one of the highest costs for any company, so ensuring that the space is used efficiently is essential.
2007/2/12/ · The manure issue is complex and inherently interdisciplinary but, more fundamentally, it requires systems thinking. Current policies, technologies, infrastructure, incentives and modes of thinking about the problem fail to consider the system-wide implications, and thus fail to foster the creation of new and innovative solutions.
2023/6/12/ · Adopting waste-to-wealth strategies and circular economy models can help reduce biowaste and add value. For instance, poultry farming is an essential source of protein, and chicken manure can be converted into renewable energy through anaerobic digestion. However, there are a number of restrictions that prevent the utilization of
2023/7/27/ · 2.1.1. Design of Cattle Manure Fermentation Tank Based on Target Compost Amount In the operation of cow dung composting equipment, the design of inlet and outlet is very important. This paper believes cow dung import and export should be based on the fermentation tank’s structural size and target compost amount. The
Space utilization data facilitates decisions based on objective metrics that help you use your space as efficiently as possible. An inefficient use of space directly translates to an inefficient use of funds. If you fail to track your space utilization, you’re essentially throwing away money. Tracking space utilization allows you to identify
