O le crawler-type turner ose auala e fa'afefeteina ai faaputuga eleele, ma o le auala sili lea ona taugofie e fa'asaoina ai le palapala ma tagata faigaluega i le taimi nei. O mea e manaʻomia ona faʻaputuina i faʻaputuga, ona faʻafefeteina lea ma faʻafefeteina e le masini liliu, ma faʻapalapala mea faʻalaʻau i lalo o tulaga faʻafefe. Pe a galue le masini liliu, sludge, pipiʻi moa lapisi ma isi mea e mafai ona fefiloi lelei ma sigi ma vaomago efuefu, fausia se siosiomaga e sili atu aerobic mo le fermentation o mea. I le faagasologa o le fermentation, e mafai ona puipuia lelei le gaosiga o kasa leaga ma malodorous e pei o le hydrogen sulfide, amine gas, indole, ma isi, ma ausia manaoga o le gaosiga o le siosiomaga.
