AEROBIC DIGESTION: (00:00)
is a process in sewage treatment designed to reduce the volume of sewage sludge and make it suitable for subsequent use. More recently technology has been developed that allows the treatment and reduction of other organic waste, such as food, cardboard and horticultural waste. It is a bacterial process occurring in the presence of oxygen. Bacteria rapidly consume organic matter and convert it into carbon dioxide, water and a range of lower molecular weight organic compounds. As there is no new supply of organic material from sewage, the activated sludge biota begin to die and are used as food by saprotrophic bacteria. This stage of the process is known as endogenous respiration and it is process that reduces the solid concentration in the sludge.
ANAEROBIC DIGESTION: (05:08)
Organic waste material (for example food wastes or sewage sludge) is stored in an oxygen free environment (usually a sealed tank or container and commonly referred to as a digester) in the presence of a population of anaerobic micro-organisms.
In this anaerobic environment, biochemical reactions occur that convert organic polymers from the feedstock into methane rich biogas and nutrient rich digestate.
Anaerobic digestion works best at temperatures of 30 - 60°C. Between 30 and 40°C, mesophilic bacteria are the principal micro-organisms present. At 40 - 60°C, thermophilic bacteria are used.
The anaerobic digestion process typically takes anything between 14 and 40 days to complete but this varies upon numerous factors including feedstock type, micro-organism population, temperature and pH
WHAT TAKES PLACE IN THE ANAEROBIC DIGESTER (07:18)
Simply animation about what takes place in the anaerobic digester (Process of anaerobic digestion). How Biogas is processed and used for a variety of energy needs, such as the generation of heat, power and fuel.

Wow! Please explain to me in more detail...
Oh yeah, I'm going to subscribe to your channel for sure. You've got 29 subscribers so far. And I'm going to be the number Dirty Thirty, lol! Hey man, have fun... 🦊
Very nice information expressed in simple way.
Thanks
Thank you very much for your simple and engaging explanation Sir ..This video really helped a lot. 🙏🙏🙏.
Great, thanks for feedback
Mention not Sir..Have a great day ahead 🙏🙏🙏.
Yeah, a little too simple. My daughter has better command of language. She's 4 days old, a fucking genius I'm telling you!
I'm rich bitch!!!
@@TheRealElectrofox are you being sarcastic?
@@TheRealElectrofox I dont understand, what you say
Thx 4 the lesson
No problem, watch rest of my videos SHARE, LIKE, COMMENT also look at my crowdfunding campaign: www.indiegogo.com/projects/engineering-educational-youtube-channel--5/x/17344431#/ - SHARE also this campaign
Thanks a lot for your efforts
excelente, el comportamiento de los microorganismos
Thanks for nice feedback
Which digested slurry Anaerobic/Aerobic is good for plants. Since plants roots need more oxygen to thrive is Anaerobic good or bad ?
In aerobic reactions, the main ions produced are hydrogen ions (H+) and hydroxide ions (OH-), as well as ions of nutrients such as nitrate (NO3-), sulfate (SO42-), and phosphate (PO43-).
In anaerobic reactions, the main ions produced depend on the specific type of anaerobic process. For example, in anaerobic digestion, the main ions produced are hydrogen ions (H+), carbonate ions (CO32-), and bicarbonate ions (HCO3-), as well as ions of nutrients such as ammonium (NH4+), phosphate (PO43-), and sulfide (S2-). In fermentation, the main ions produced are also hydrogen ions (H+) and sometimes acetate ions (CH3COO-), but the nutrient ions produced can vary depending on the specific type of fermentation
Thanks for the lesson.I couldn't differentiate the two processes.
No ptoblem, please share, like my video and channel
Chips choppas
Sir how many days take new biogas plant to produce gas in winter
depends, there is so many factors which desides this, as you know scraping in winter is slower then in summer, maybe to see this article maybe will help www.wecf.eu/download/2008/Biogascoldclimates_WEB-WECF0608.pdf
Too cool for school ay
Is it good comment or?
chrvoje engineering I love you rlly good vid
can you please share the reference
Reference what you mean
@@chrvoje_engineering please mention from which book or research paper you got this information
Thank you this helped me understand digestion better but you have a lot of errors in spelling and grammar.
Really? You, beginning with a capitalized letter and ending with your period, in your statement. You complain of incorrect grammar but you packed three sentences in between that capitalized letter and. With no commas. There should have been three qualifiers. There weren't. I'm sorry, I'm not trying to hate on you, I'm just saying that if you were going to be correcting people on grammar, you are to look at your sentence structure. I love you, take care and keep up the fight! E pluribus unum!
✌🤞🖖🤘🤙👏👍👌👋🤟
Thanks :)
we need some memes in these comments...
i painted my x box controller white so i woulden't die
?
Wtf? Lololol! Do whatever it is that you do!
