Narrative:
On departure from slc with a normal 1 bleeds off takeoff, a loud popping sound and rush of air was heard when the right bleed air valve was opened at 5500 ft MSL. Soon thereafter, the lead flight attendant reported smoke in the cabin. At that time the captain directed me to initiate the 'smoke removal and identify.' the captain flew and talked with departure and tower. I completed the emergency checklist and maintained communication with the cabin. With checklist complete, the smoke began to dissipate and was almost gone by landing, according to the lead flight attendant. After landing and confirming with flight attendant and fire trucks that there was no indication of fire and smoke, we taxied to the gate. Takeoff to landing was 9 mins. From report of smoke to landing was approximately 6 mins and very busy. All emergency and normal checklists were completed in accordance with operational procedures. Supplemental information from acn 356711: I declared an emergency. I walked back in the cabin and I noticed several rows of oxygen masks were down. The flight attendant said several passenger had forced open the mask doors and pulled the masks out. I had no indication of this prior to the passenger leaving the aircraft. I have no idea how this could have been prevented.
