POST-TREATMENT

Post-treatment for MFMicrofiltration (MF) membranes:
 Microfiltration membranes are typically hollow-fibers with a pore size range of approximately 0.1 – 0.2 μm (nominally 0.1 μm). and UFUltrafiltration (UF) membranes:
 Ultrafiltration membranes are typically hollow-fibers with a pore size range of approximately 0.01 – 0.05 μm (nominally 0.01 μm). water treatment systems is essentially the same as for conventionalConventional treatment:
Conventional treatment refers to older established water treatment process such as coagulation, flocculation, and rapid sand filters. treatment and typically consists of disinfection, fluoridation, and corrosion control.
