I use this combinator to control my k2 pollutionscrubbers.
My hole base had in every productionchunk one scrubber with a inserter for the filters controled by a pollutioncombinator. I will take a look very soon.
Over all in my opinion its not needed to calculate the polution every half second ... 1 to 5 seconds are ok ...
