I-SD-200 Desander ingumshini wokuhlanza udaka nomshini wokwelashwa owenzelwe udaka lodonga olusetshenziselwa ukwakhiwa, ubunjiniyela besisekelo senqwaba yobunjiniyela, ubunjiniyela bomhubhe ongaphansi komhlaba nokwakhiwa kobunjiniyela bokumba. Ingalawula ngempumelelo ikhwalithi yesilayidi sodaka lokwakha, ihlukanise izinhlayiya eziqinile-zoketshezi odakeni, ithuthukise isilinganiso sokwakha i-pore yesisekelo senqwaba, inciphise inani le-bentonite futhi inciphise izindleko zokwenza i-slurry. Ingakwazi ukubona ukuthuthwa kwemvelo nokukhishwa kwe-slurry yemfucuza yodaka futhi ihlangabezane nezidingo zokwakhiwa kokuvikelwa kwemvelo.
