Here are a few ideas for the do-it-yourselfers...
Scrubber Tower Packing
4metals mentioned a lab bench sized scrubber consisting of two 4 liter flasks filled with marbles. 8 liters of marbles will cost about $200! Perhaps quartz pebbles would be an alternative.
For full-sized scrubbers, let's do the math. Say you want to fill it with Bio Balls. They cost about $100 for 15 gallons of balls.
If your tower is 12" in diameter and you want to fill 5 feet with bio balls, the volume is pi times the diameter squared divided by 4 (same as radius**2), times the length. So pi (3.14) times 1 foot times 1 divided by 4, times 5 =
pi * 5/4 = 3.93 cu ft or 29.4 gallons. Call it 30 gallons, so it will cost $200.
If the tower is 2 feet in diameter, the volume is pi * (2 * 2 / 4) * 5, or 5* pi, which is 15.7 cu ft = 117.5 gallons. Divide by 15 and we get 7.83, so it will cost $783 for just 5 feet.
Plastic snow fence has been mentioned before as an alternative to expensive random packing. It sells for about $20 for 50 feet x 4 feet at Home Depot. I'd suggest using that, and then filling the voids with about $50 of bio balls. (Continued next message).
