E toru nga taika kua whakauruhia (te whakakotahi i te tank, te whakaranu i te tank me te waahi rokiroki) te pupuhi tonu, te ngawari ki te whakahaere me te whakamahi;Ko te rerenga wai kotahi me te inenga ka taea te whakatika noa, a ka taea te whakarereke i te kukū o te whakarite reagent me nga whakaritenga o te tukanga.Ka whakamahia te Microcomputer ki te whakahaere tika i te rere o te wai kotahi me te inenga, a, ko te wehenga kukū o te reagent kua rite he iti iho i te 5% o te uara kua whakaritea;Ka whakamahia te kaitao wai ultrasonic ki te kite i te taumata o te wai, me te nui o te aro, kaore te tauhohenga e pa ki te kawe o te otinga, a, kaore i te iti te kukū o te whakarite flocculation.Ko te miihini katoa he kowiri tira, he nui te kaha o te miihini, kaore he rereke me te roa o te ratonga.
