My memo
My technical article talks about the desalting process which is the most common technology for handling seawater to fresh water.
There are two basic ways to do this process. First of all, that is membrane process. Membrane processes can be either reverse osmosis (RO) or electro-dialysis (ED).
RO is the procedure to use high pressure pumps to force seawater through a semi-permeable membrane. The semi-permeable membrane is about one one-millionth the diameter of a grain of sand. Because it is so small so that it can filter almost everything in sea water including salt molecules and we can keep refresh water.
ED uses an electrical current to isolate salt and impurities through the use of a semi-permeable, ion-selective membrane and we also have the fresh water.
Additionally, Thermal distillation is one of the best methods of desalinating seawater. The method is so easy, just vaporizing sea water and condensing the vapor form to the liquid form. Finally, we have the fresh water with a small amount of salt.
i think your memo basically satisfies the require of the exercise. Howerver, in my opinion,there are 3 things you need to improve:
Trả lờiXóaFirstly, you should bring the original science report along with your memo to make it move convenient.
Secondly, in the 6th line, i think you want to mean "the membrane pore" is small not "the membrane" itself.
Thirdly, i think you should explain more what is a "semi-permiable membrane"

I like your memo about two technologies which are used to desalt seawater.
Trả lờiXóaAnd you article also really clear and easy to understand.
