Anaerobic digestion Specifically, we will study a process that combines anaerobic digestion with algae cultivation on the digester effluent. Yuan XZ, Shi XS, Yuan CX, Wang YP, Qiu YL, Guo 2013; Mahdy et al. This technology has The conditioned algal biomass will then enter the anaerobic digestion section where it will be fermented for 4-6 weeks and subsequently attacked by suitably chosen enzymes which will convert the contained lipids and proteins into methane and CO2. This resulted particularly in increased ruminal proportions of t11 18:1 rather than a shift to t10 intermediates, suggesting that both young and adult goats might be less prone to dietary induced shifts toward the formation of t10 intermediates, in comparison with cows SINO MICROALGAE have three cultivation farms and the total cultivation area is about 1 Anaerobic digestion (AD), which converts organic matter into biogas and a stabilised digestate, is a proven technology for the management of organic-rich streams ( Mata-Alvarez et al., 2014 ). Adding algae decreases the capacity of the digestion and Anaerobic digestion of Algae Appl Microbiol. Anaerobic digestion of algal biomass could theoretically reduce costs associated with drying wet biomass before processing, but practical yields of biogas from digestion of many algae are substantially below the theoretical maximum.

Anaerobic digestion is the process by which organic matter such as animal or food waste is broken down to produce biogas and biofertiliser. The digester will convert organic material into energy-rich biogas while In some cases, separated algae waste is added to anaerobic digesters that receive primary and waste activated sludge (WAS). Anaerobic digestion of Algae Appl Microbiol. Anaerobic digestion is a process through which bacteria break down organic mattersuch as animal manure, wastewater biosolids, and food wastesin the absence of oxygen. Mixed algae cultivation in raceway ponds on nonagricultural sites is a known and favoured techno-economic approach to producing renewable energy through AD of microalgae (Zamalloa et al. Besides being an extremely nutritious food, oxygen producers and food base for all aquatic life, they are increasingly used for industrial purposes. In doing so, it reduces the Anaerobic digestion is a well-established technology for treating organic wastes with high water content and that are very prone to biological degradation. Improving the hydrogen yield could be done by hydrolysis and tuning nutrients. Algae Grasses. Phototrophic microalgae require light, carbon dioxide, water, and inorganic salts to grow. In order to minimize costs, algal biofuel production usually relies on photoautotrophic culture that uses sunlight as a free source of light. 2015; Olsson 2018).

As a renewable energy, methane can be used for combustion, electricity and transport, reducing dependence on fossil energy ( Novais et al., 2018 ). Similarly, improved biogas production may be obtained from anaerobic co-digestion of algae and cattle dung by maintaining mesophilic temperature conditions throughout the year. phosphorus). New processing methods are needed to reduce costs and increase the net energy balance. Algae that are grown in wastewater treatment lagoons could be an important substrate for biofuel production; however, the low C/N ratio of algae is not conducive to anaerobic digestion of algae with economically attractive methane production rates. DOI: 10.1128/AEM.5.1.47-55.1957 Corpus ID: 40166824. The culture temperature should be between 15 and 30C (~60-80F) for optimal growth.

This waste stream contains leftover liquid from the anaerobic digestors that would provide necessary nutrients like nitrogen and phosphorus for the microalgae to grow and it can be pumped directly into the microalgae ponds. By John J Milledge. Anaerobic digesters are built systems (lagoons or tanks) where anaerobic digestion takes place. Typically, aerobic treatment is applied to treat low strength wastewater (COD <1000 mg/L) when the treatment requires the presence of oxygen. The biogas Authors C G GOLUEKE, W J OSWALD, H B GOTAAS. Anaerobic digestion of algal biomass produces a nutrient-rich digestate containing both nitrogen and phosphorus nutrients. Digestate nutrient values of 2940 mg/L ammonia-nitrogen, 390 mg/L of total phosphorous, and 320 mg/L of potassium have been reported by Collet et al. [1].

In some cases, separated algae waste is added to anaerobic digesters that receive primary and waste activated sludge (WAS). Algae that are grown in wastewater treatment lagoons could be an important substrate for biofuel production; however, the low C/N ratio of algae is not conducive to anaerobic digestion of Algae, a photoautotroph which could convert sunlight energy to chemical energy, is a promising feedstock option for anaerobic digestion compared to other organic solid waste due to the high yields without any requiring of use of arable land and fresh water resource showing low threat on food market ( Rodriguez et al., 2015 ).
