Hollow fiber membrane modules yog asymmetric (tsis yog -uniform) tus kheej - txhawb nqa daim nyias nyias uas tuaj yeem rov qab ua kom muaj txiaj ntsig zoo tshaj plaws ntawm kev hla - ntws pom. Qhov no geometric configuration ntawm lub hollow fibers maximizes daim nyias nyias cheeb tsam nyob rau hauv qhov tsawg tshaj plaws qhov chaw. Nws muab faib ua ob hom lim membranes: sab hauv siab hom thiab sab nraud siab hom.
