Izindleko zomhlaba, zokwakha kanye nezabasebenzi ziyongiwa njengoba lo mshini uthatha indawo encane phansi ngesakhiwo sawo esilula, izidingo ezincane zokuntanta kanye nokusebenza okuzenzakalelayo ngokuphelele.

Ngokuvamile kubekwa phambi komshini wepuleti kanye nohlaka noma i-centrifuge ukuze kuncishiswe amandla okucubungula imishini yokususa amanzi kamuva.
