Membrane Filtration: RO
RO PA TFC SW WR to RO REJECTION LOG
Pressure-driven membrane filtration design parameters for MF, UF, NF, and RO systems — flux, TMP, pore size, MWCO, recovery, contaminant rejection (turbidity, bacteria, virus, TDS, NaCl, hardness, organics), fouling potential, cleaning frequency, and module configurations. Covers drinking water, wastewater reuse, leachate, and industrial applications.
