Hi, please can anyone tell me what is the meaning of waste stabilization? I am doing a research about the anaerobic digestion of food waste and i don't know what that definition means. Note: i am just 16 years old because i know that someone may considers my question very easy to answer but i really need help. Thanks in advance!

I am sorry but i can't understand well, my original language is not English. Do you mean that the flash point/heat of combustion is itself the auto-ignition temperature? Do i do the experiment using a bomb calorimeter?

About the pressure .... do you mean like this? And about the auto-ignition, i do know that i must do an experiment, but i don't know how. I don't know the tools, the practice ....etc, i need to know. Thank you

If i have a closed system and i want to raise its temperature by raising the pressure to make an autoignition process, how do i control pressure and raise it? And please, what are the methods to determine the autoignition temperature of a solid substance? Note: I am just 16 years old and i am doing a scientific research for a competition, so i need help, please. Thanks in advance..

Thank you so much! I got benefit of that! But please, what is the difference between Total Dissolved Solids (TDS) and total heavy metals? And the coagulant should remove both of them in addition to the organic matters, shouldn't it? Excuse me, may i ask you a question out of this topic? Why gases separation by density is high-cost? Does it require high energy/temperature for separation process?

This is a scientific research that i am doing to enroll a competition, i am just 16 years old so i need some help, please..

Thank you all. So, it is called compression ignition.

What is the required-to-determine parameters for the test of a water turbidity coagulant? And what are the standards for a coagulant practice?And what are the differences between compliance monitoring, performance monitoring, and control process in wastewater treatment? With references, please... Thanks in advance...

I have read about a technique that uses very high pressure so that temperature gets very high in order not to use any type of power or energy and the selected thing burns....may any one explains me more details about this technique, what is it called, how true is it because i have a doubt about it. Thanks in advance..

So, i want to know about this technique.

There was a doctor told me that, too. But this was applied by a junior student at Intel ISEF competition and she received a top award for it.

This is an electronic device separates gases under high temperature and pressure according to their sizes or densities, may any one explains my this technique in details or recommend my anything explains it? Thanks in advance...

what is the rang of the cost of high temperature gas separation by membranes(i have a lot of heat in my research) ? what is the cost of gas separation by membranes in general? Where can i get those membranes or made them?

okay .... thank you so much for helping me!

very expensive!! i know someone who did this with a cost up to only 5 or 6 dollars!! here is the device which this one made :(click on the photo so that you can see it clearly: http://www8.0zz0.com/2016/10/21/08/241831114.jpg

i want to separate gases produced from the combustion of organic matters (co2, h2o, and other minor gases)to benefit from each one at a time.

Hi, i am a junior student doing a research to take part in a world competition, a very important chapter of my research paper depends on gases separation to benefit from each one at a time, i searched about gases separation techniques but i found most of them very expensive and complex. Lately, i found out a method depends on an electronic device that separates gases according to their different densities under high temperature amounts to 1200 C in a closed system. Please could any one recommend me a book/reference/research paper/any thing explain me this technique or any thing explains gases separation by density in general because i strongly need it. Thanks in advance...

i googled what i need and you are right, information is everywhere but i need ( scientific, trusted ) reference, this one of the rules of doing a scientific research so i need books not websites. In addition, i am a junior student and i am doing a scientific research for the first time in my life to take part in a competition, so i have some problems about scientific references.

Hi, please recommend me any article/book/any scientific reference talks about effects of wastewater on environment, and another talks about effects of drinking contaminated water on human health; because i searched but i couldn't find what i need for my research in environmental engineering. Thanks in advance...

the girl is called Yasmeen Yehia Mustafa, this is only mentioned, thank you very very much, you helped me a lot !

this method is applied by an Arabic girl (minute:10.30)but the video is Arabic:

yes it is new but unfortunately this is what all i could know about it.

i am trying to separate these gases to benefit from each one of them, but when is searched about gases separation techniques and i found them expensive and complex and i lately heard about an electronic device does this mission according to densities differences , it is fairly cheap and simple and i need to read more about is : what is this method/technique called ?what good books talk about them?

thank you so much but this is not what i need to know, what i need is : there is a cheap electronic device separates gases according to their different densities, what is this method/technique called ? what are good,easy-to-understand books talk about it?

if i burn organic matters in a closed system, it produces carbon dioxide, water steam, a lot of heat, and other minor gases. my question is : how to separate these gases from each other ? i have heard about an electronic device used for this mission according to densities differences. what is this technique called ?and i need a good,easy-to-understand book about it. thanks in advance...
