Just for the record, the math on this page is wrong. It says atomizers destroy 2 waste per day, pumps remove 4 polluted tiles every day, producing 1 waste every 6 tiles, and generators generate 2 polluted tiles per day. It then says that 1 atomizer supports 4 pumps and 8 generators.
If the building numbers are correct, this should actually work out to 1 atomizer supporting 3 pumps and 6 generators.
Since I haven't tested this in game, I'm not going to edit it yet. Please double check my math but:
atomizer: -2 packs/day
pump: +4/6 packs per day, -4 pollution/day
generator: +2 pollution/day
1 atomizer, 3 pumps, 6 generators:
(-2 packs) + 3(4/6 packs) = 0 packs
3(-4)pollution + 6(2) pollution = 0 pollution
