<span>A method of processing coal to remove contaminants by mixing coal in a solution of potassium permanganate in a selected concentration range, rinsing the coal, mixing the coal in a solution of ammonia hydroxide in a selected concentration range to cause the solution to be brought into contact with the surfaces and pores of the coal, discharging the processed coal from the second reaction vessel, monitoring the process to detect when the concentration of aqueous ammonia in the second reaction vessel has fallen below the selected range, and feeding aqueous ammonia solution with an ammonia concentration in or above the selected range to the second reaction vessel to return the solution to within the selected range.</span>

Answer:
I don't think it was because your room wasn't clean. The main cause of bed bugs is travel, which means most likely you got one on you when you went outside or something, and you accidentally got it into your room. Bed bugs hitchhike on luggage, clothing, people, etc.
If there are blood stains or dark/rusty spots on your bed/pillow, there are definitely bed bugs. The bloodstains/spots come from you crushing the bed bugs accidentally. The place where bed bugs are (in this case, your room), may also begin to smell bad. You might also see eggs laid by the bed bugs.
Let me know if you have any other questions. Good luck!
