2023/1/31/ · Temperature plays an important role in anaerobic digestion (AD), and different substrates have different optimum temperatures in AD. However, the effect of temperature on the performance of AD when cellulosic ethanol wastewater was used as a substrate was rarely reported. Therefore, the digestion characteristics of cellulosic ethanol

2024/5/23/ · 1. Fermenter Vessel. A fermenter is a large cylinder closed at the top and bottom connected with various pipes and valves. The vessel is designed in such a way that it allows to work under controlled conditions. Glass and stainless steels are two types of fermenter vessels used. The glass vessel is usually used in small-scale industries.

2023/3/9/ · Later, it was used to process manure from 100 cows and was found to perform satisfactorily, producing a proportionally increased rate of gas. The digester was designed and constructed during 1974 and 1975. Operation began in the fall of 1975 and continued until the cows were turned out to pasture in the spring.

2022/9/2/ · Quantitative comparison of anaerobic fermentation (135 processes and reactors) was conducted. As for the operating cost of different fermentation processes, the establishment of DIET in high-rate reactors could reduce the cost by 60% from single-stage fermentation, and the two-stage operation induces an additional 30% reduction.
