I'll expect some response from the marine & chemical engineers here.
I spend last weekend on the beach at Dapoli (Konkan, India). Its a beautiful place to visit. I was hurt to see that such a beautiful place has a polluted sea. I could see all different colored chemicals floating on the water I was wondering if we'll ever be able to make the sea pollution free. Any ideas, folks?

I guess I should clarify the purpose of this thread.
Are there any technical solutions to the problem that's being discussed?

Indeed.. prevention is better than cure. That should probably a principle for engineers. But anyway, we should still think of a way to fix the existing pollution problem.
Regarding chemicals.. maybe we should approach it like how oil spills are cleaned up. One can use "sorbents" to absorb the chemicals from the water like a sponge. Another method is to use biological agents to break down the chemicals into harmless compounds. Of course, thats as much as I can contribute regarding to technical stuff

Oh, thats interesting! So then we could just scoop them up from the bottom? Maybe a underwater collector robot can clean them.
I just stumbled upon a shelf in the uni library, displaying books on Water treatments and engineering. Gonna be a long read for sure.

Hey, what about if we equip a hive of small autonomous boats equipped with "sorbents"? They can have chemical detectors and share information from each other wirelessly, combined with aerial and satellite images. This could possibly enchance the cleaning efficiency. The "boats" don't have to be fabricated with expensive designs.. they just need to float and propell across the water. In fact, we can add solar panels so they can remain in sea longer (and extend mission range). A single "command" boat, operated by humans can be used to launch these small boats and observe their operation.
Some info of sorbents here: Sorbents | Comprehensive Procurement Guidelines (CPG) | Wastes | US EPA I skimmed through a waste water book. Ya know the pipes that go into the sea from the beach? It consist of processed waste water, but other wastes still get mixed into it. They are then diffused far away into the sea. Unfortunately.. a "plume" of waste can occur just below the water level.. so we might not actually see the extent of how polluted the sea really is. Anywayz, the book got into some detailed diffusion analysis.. I proceeded to put it back in the shelf :P That got me wondering. For landlocked countries.. are rivers their only waste water outlet?

Alright, here's the idea in a diagram. The "pink" boat represents the Command Ship, while the yellow ones are the robots. White dashed lines are the communication links between the Command and robots, while the red lines represent inter-robot ad hoc communications. Forgive me for my choice of colours.. I was rushing it a bit
![]() Software: Inkscape. Used the freehand function to draw the outlines of the chemical dispersion, and simply used Fill. Skewed the water textures to give it that isometric view.. though the angle is not exactly 60o!

Well, the idea is good but I think it is not practical. Well, as MayurPathak says, the boats will have to cover the entire sea (which makes it impractical).
I'd say let's accept the damage done till now. Let's think of what can we do to prevent the sea from polluting further. How can we stop the pollutants from entering the sea?
