Can you please help me make this more formal ; same ideas but make the gamma better and make it sound better.?

we can make a big machine to take sea water and garbage in and
it separates the sea water and the trash; the sea water will go through the small hole; and the garbage are to big to go down so it separates the sea water and the garbage

then the machine will dump the garbage in the garbage factory it can recycle plastic and paper and the other waste get burned

then the machine will dump the ocean water back to the ocean

every 3 km will have a factory like this

Additional Details
same ideas but better grammar and more formal

THANK YOOOOUUU!!! :) :)

We can make a machine which would intake sea water with garbage and separate the sea water and the trash.The sea water will penetrate through the sieves wheareas the garbage ,which is too big to pass through the sieves, would seprate out.The garbage thus collected can then be dumped in some garbage factory where the recycleable material like paper etc can then be sent for recycling purpose and the rest can be dumped by suitable methods.And the water collected in the mahine/equipment can then be discharged/released back to the ocean.
We can have a series of factories like this at a distance of 3 Kms each.

Hope this helps!!!

I think it is not a bad idea to make sea clean but it looks like difficult. i have no idea but i will try to help you in
this you can make big hole. It should be in water. when water comes in garbage will store inside the tube hole
and all water goes out by this way you can do this.
