Engineering - October 2007

I need to dechlorinate some water flowing at about 5-20 gpm. To do this, I want to build an activated carbon water filter large enough that I don't have to replace the carbon too often. I have some ideas, but information about carbon filters is suprisingly scarce. Does anyone have any ideas about how to design such a filter?

this is the 3rd time im asking T_T , i dont think i made the last one clear enough. so there's 2 circuits, parallel and series each with 4 bulbs (the 2 batteries are not in parallel in the parallel circuit, in both circuits the batteries are side-by-side). in the series circuit, the bulbs are lines up. in the parallel, the bulbs are in parallel, each with their own path. if it is series, is it because when energy goes through the filament (the resistor in this case) it's converted into light and heat, but when it goes past the resistor, the energy is transferred back into it's original power? what if it doesnt? does the first bulb closest to the positive ( i think energy goes positive to negative terminal) terminal appear brighter than the rest? and the fourth bulb the dimmest? what about parallel. lets say the total voltage is 12V. does each bubl get 3V ea then? please explain.

I am a second year Computer Engineering Technology student and I am think about getting work in a recording studio, what you you recommend as far as education goes? The only recoding engineering program in my city is a specialization in a music diploma. I do not necessarily want to got school for 2 years to learn music engineering. I was think about learning more about the equipment and approach the positions as some who knows a bit about the equipment and can do basic troubleshooting.
