I-Dewatering screw press isetshenziselwa ukuqina okusebenzayo kanye nokukhipha amanzi e-sludge.Amanzi e-sludge angamanzi anenani lezinto eziqinile ezimisiwe, ezingakhiqizwa ekuhlanzeni amanzi angcolile, imboni yokucubungula ukudla, imboni yamakhemikhali namanye amagatsha omsebenzi womuntu.

Umshini wokuthulula amanzi we-screw-press sludge uyisisetshenziswa esisha sokuhlukanisa uketshezi oluqinile, esebenzisa isimiso sokukhipha isikulufu, ukhiqiza amandla aqinile okukhipha amanzi ngokushintsha kwe-screw diameter ne-pitch, kanye negebe elincane phakathi kwendandatho ehambayo nendandatho engaguquki. , ukuqaphela ukuchithwa kwamanzi kwe-extrusion of sludge.
