2023/3/12/ · In this study, we present a conceptual design for a small-scale water purification treatment unit using reed bed eco-friendly filtration that can be used in remote and underserved communities. Our design is based on a combination of different treatment and technologies, including filtration, disinfection, and adsorption.

2023/11/1/ · 1. Introduction. Food waste is an important part of urban solid waste, accounting for about 50∼55% of the total domestic waste in developing countries (Troschinetz and Mihelcic, 2009).It is estimated that, the global amount of FW will be as high as 2.5 × 10 9 metric tons by 2025 (Karthikeyan et al., 2018, Chen et al., 2015, Xu et al.,

2024/3/1/ · After semicontinuous co-fermentation, the waste fermented residues were dried at 105°C, followed by incineration at 700°C for 3 hours in a muffle furnace (KMTF-1000-1L), resulting in the production of titanium-rich incineration sewage sludge ash (Ti-ISSA). It constituted a small fraction in C0 (1.80%) but represented 20.97% and

2022/2/8/ · Anaerobic fermentation technology is one of the effective ways to produce biogas energy from biomass waste. Biomass anaerobic fermentation is the effective conversion of organic matter in biomass under the assimilation of anaerobic bacteria, and finally produces methane and part of carbon dioxide with economic value, which can be

Fermentation types are classified into different classes: 1. Based on various aspects like based on feeding substrate to fermenter. 2. Based on need of supply of aeration 3. Based on need of light etc. 1. Based on feeding substrate to fermenter: There is Batch fermentation; Continuous fermentation and Fed-batch fermentation

2013/1/1/ · It is necessary to design specialized devices for solid-state fermentation. This section provides discussion of this issue. 2.3.1 Large-Scale Aseptic Techniques for Solid-State Fermentation. Solid-state fermentation is a technology with a long history, and in most cases, traditional solid-state fermentation does not consider aseptic operation.

2018/6/2/ · The unit is chemically resistant, stainless and suitable for producing biogas from generated liquid waste in both the city and villages (Small Biogas 2010). The main features of the bioreactor: Bioreactor is integral and hermetic. Smooth and strong surface. Easy to transport. Special casing for use on the ground or underground

2022/3/24/ · 1. Introduction. Fermentation has been practiced over many centuries to produce bread, beer, cheese and wine. Through human activities and experience, cereals, root tubers, and fruits and vegetables have been used to produce fermented solid foods and alcoholic and non-alcoholic beverages.
