I've never actually tried it but I have heard on numerous occasions that adding citric acid to urine can rid it of heroin, be careful though because I'm not 100% sure.
Not as long as it really is urine and there is no dope in it.
If you mean would bleach remove heroin from a urine sample the short answer is no heroin is a drug not a bacteria or virus if bleach was added to urine it would definitely not take the heroin out of the urine if it were present.
It is not possible to clean heroine out of a person's urine.
Stop taking heroin.
I'm still trying to puzzle out "second hand heroin." What did you you do, mug some junkie for his blood and inject it into your own veins? Being around people who have used heroin shouldn't get enough of it into your system to matter. That said, if you are required to take urine tests, it's probably a really bad idea for you to be hanging out with people who use heroin, for multiple reasons.
8 hrs?
Heroin will be out of most people's systems in 1 to 3 days. Four days will be beyond the threshold, since Heroin is water-soluable, so it will not show in your urine.
No, opium and heroin are different substances and will show up as separate substances in a urine test. Heroin is derived from opium, but they have distinct chemical compositions that can be distinguished in drug tests.
Heroin will usually stay in your system for 2-5 days. Drink several glasses of water so you urinate as much as possible before your drug test. But, be warned that drinking enough water to flush your system will result in clear urine which will be considered too diluted and you will fail your drug test. After you've drank enough water, and your urine is clear, drink enough soda to make you urinate a couple more times to make your urine a yellowish color.

No heroin can not be flushed from one urine, it goes to the brain.
