Imiterere ya reaction ya IC irangwa nuburebure bunini bwa diameter, muri rusange kugera kuri 4 -, 8, kandi uburebure bwa reaction bugera kuri 20 ibumoso m iburyo.Imashini yose igizwe nicyumba cya mbere cya anaerobic reaction nicyumba cya kabiri cya anaerobic.Gazi, ikomeye kandi isukuye ibyiciro bitatu bitandukanya bishyirwa hejuru ya buri cyumba cya reaction ya anaerobic.Icyiciro cya mbere gitandukanya ibyiciro bitatu bitandukanya cyane cyane biyogazi namazi, icyiciro cya kabiri gitandukanya ibyiciro bitatu bitandukanya cyane cyane umwanda namazi, kandi imyanda ikomeye kandi igaruka ivangwa mubyumba byambere bya anaerobic reaction.Icyumba cya mbere cyitwara gifite ubushobozi bukomeye bwo gukuraho ibintu kama.Amazi y’amazi yinjira mu cyumba cya kabiri cya anaerobic reaction arashobora gukomeza gutunganywa kugirango akureho ibinyabuzima bisigaye mu mazi y’amazi kandi bizamura ubwiza bw’amazi.
