Internship report of water purification workshop Pumping the river, precipitation of large particulate matter-quartz sand filtration 5 microns filtration accuracy-heavy metal replacement-into two good pools-and then quartz sand filtration 5 microns filtration accuracy-and then into the activated carbon adsorption-net pool What do you want to report? Pumping the river, precipitate large particles-quartz sand filtration 5 micron filtration accuracy-heavy metal replacement-enter the two good pools-then filter the quartz sand for 5 micron filtration accuracy-then enter the activated carbon adsorption-net pool you are a bit interested in this equipment? The multi-media filter already contains quartz sand filtration 5 micron filtration and activated carbon adsorption. Is there a few ozone or bleaching powder thrown in the clean pool? How do I feel like your water purification equipment is like a water filtration system.
