	Generally ESP requires high negative voltage, what will happen if positive voltage is supplied?Apart from mobility is there any other reasons for using negative voltage?

	Er, the precipitate will end up in the wrong place? __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	An electrostatic precipitator uses both positive and negative voltage, the fields can be reversed depending on application.... "There are typically three types of ESP units: dry negative corona units, wet negative corona units and wet positive corona units." Different designs for different applications...Generally speaking the particulate laden air is passed through an electrostatic field and picks up the charge, then collected on plates with the opposite charge...

	Yes, here's a research paper that explains an interesting option: http://www.isesp.org/ICESP%20VI%20PAPERS/VI-ICESP%20P353.pdf __________________ “Tell me and I forget. Teach me and I remember. Involve me and I learn.” Ben Franklin.
