If you’d like to practise the material covered in this video, check out our platform at www.cognitoedu.org - it's totally free, and has been built to make learning and revision as easy as possible. The main features are: - Lessons organised by topic, only the lessons relevant to your specific exam board and tier are shown. - Automatic progress tracking. Progress bars tell you what you’re doing well at, and what you need to spend some time on. - Practise quizzes so you can test your knowledge. You can quiz yourself on any combination of topics you like. - A huge number of fully-hinted questions that take you step-by-step through some of the trickiest calculations & concepts. - A comprehensive bank of past exam papers, organised both by year, and also by topic.

an idea for you : algae can be used to clean toxic waste pools of water and even enrich the algae for potent biofuel. Here's a breakdown of the process: **Algae-based wastewater treatment:** 1. Algae are naturally able to absorb and break down pollutants in water, such as heavy metals, pesticides, and industrial chemicals. 2. Algae can be used to create a bioreactor system, where the algae grow and absorb pollutants from the wastewater. 3. The algae can then be harvested and removed from the water, leaving it cleaner and safer for discharge or reuse. 4. The harvested algae can be further processed to produce biofuels, animal feed, or other value-added products. **Enriching algae for biofuel:** 1. Once the algae have been harvested from the wastewater treatment process, they can be further enriched to increase their lipid content. 2. Lipids are the primary components of biofuels, so increasing their concentration can lead to higher energy yields. 3. Enrichment techniques may include: * Nutrient manipulation: Adjusting the nutrient levels in the growth medium to optimize lipid production. * Temperature control: Regulating temperatures to optimize lipid synthesis. * Photoperiod manipulation: Altering light-dark cycles to optimize lipid production. * Genetic engineering: Modifying algae genomes to enhance lipid production. 4. The enriched algae can then be processed into biofuels, such as biodiesel, bioethanol, or biogas. **Benefits of using algae for wastewater treatment and biofuel production:** 1. Closed-loop system: Algae can be used to clean wastewater and produce biofuels in a closed-loop system, reducing waste and environmental impact. 2. Sustainable energy source: Algae-based biofuels offer a promising alternative to fossil fuels, with a potentially lower carbon footprint. 3. Waste reduction: Algae can help reduce the amount of toxic waste that needs to be disposed of, promoting a more circular economy. 4. Carbon sequestration: Algae can absorb CO2 from the atmosphere during their growth phase, making them a valuable tool for carbon sequestration. While this technology is still in its development stage, there are already several pilot projects and commercial-scale operations around the world that demonstrate its feasibility.
I work in an industrial factory. You should see the strict treatments we have to put our water through before it even gets sent off to a water treatment plant. Drinking water is just fine lol
Thanks Giovana! We really appreciate the comments, it’s so good to know people are getting good use out of these (they help the videos get seen)!! Hope all your work is going well 🥳

cognito must be rolling in it. Capitalising on the fact that everyone in the UK has to pass through GCSE's, they have a undying target market.
Oh oh oh my friend what about the rest of the planet in its entirerity.
@@TheL1zrd iGCSEs are also very common buddy
Very good for last minute revision and making notes!

COGNITO YOU ARE LITERALLY MY LIFESAVER THANK YOU SO MUCH FOR MAKING SUCH AWESOME VIDS LIKE ALWAYSSSSSSSSS
this is better than my teacher from yr10 cant lie
Lockdown lessons. Anyone else?
Yup
yup
Yep
Yup
Yep
0:04 why were my first thoughts "Cake"
😡
Not gona drink water anymore
rip

@@ninjabrawlstars5341 what sort of question even is that.
@@ninjabrawlstars5341 well I'm 17 and it says GCSE chemistry? Done my GCSEs last year 😂
Has bioleaching and phytomining been covered on the channel? Love the videos by the way!
That's what I am looking for now, did you have any luck finding if they did cover it at all?
@@bethmonger78 I’ve looked too, I don’t think they have done one, however the channel Kayscience is another good channel which covers both
Cool video, knew that some water came from this, but not exactly how it was done, cool and informative. Thanks
i think the sludge just means poo or shite 😂😂
Why don't we treat sludge aerobically just like the effluent tank?
because methane supplies us with energy because its an energy source moreover the remaining digested waste could be used as a fertilize
GOOD LUCK EVERYONE
Thanks
I'm being forced to watch this for my science homework 😭😭😭
fellow yuqi stan i see
Good work i have learn
a lot from you
great!
Thanks Giovana! We really appreciate the comments, it’s so good to know people are getting good use out of these (they help the videos get seen)!! Hope all your work is going well 🥳
They are thanks! Partly because of your videos!
Hmmm
im so cooked for my gcses🙁
I swear you bubble it through chlorine is the last stage and I never learnt about after sedimentation
Nice 2
Nice
damn
Dammmmmnnnnnn
I really don
