Isihlungi se-String sediment sediment filter sinikeza ukujula kweqiniso okunamandla okubamba ukungcola okuphezulu kanye nokufuduka kwemidiya okuphansi kakhulu.
Isihlungi sikhiqizwa kusetshenziswa isivinini esikhulu, inqubo yomoya eqhubekayo edala isihlungi sesiqephu esisodwa esinamakhulukhulu emihubhe emi njengedayimane eba mancane kancane kancane ukusuka kububanzi obungaphandle ukuya kunkambo.
Izinhlayiya ezicolekile zibambeka ngokuqhubekayo njengoba uketshezi luhamba luye phakathi nendawo yesihlungi okuvumela amandla okugcina amakhulu kakhulu kunalawo ahlotshaniswa nemidiya yesihlungi esingaphezulu esinobukhulu obufanayo kanye ne-porosity.
