Molecular weight

The characteristics and behaviors of soluble microbial products (SMP) in sequencing batch membrane bioreactors (SBMBRs) were investigated at various sludge retention times (SRTs). SMP concentrations in SBMBRs reached a minimum at SRT of 40 days and were consistently higher than those in effluents. T

Alkylphenols (APs), such as nonylphenol, are well-known as endocrine disrupting compounds (EDCs) and have been observed in aquatic environment. In this work, we focused on the rejection properties of NF membranes for APs. The rejection properties for 10 kinds of APs (alkyl group: C2–C9) were examine

Fouling characteristics of membranes with various molecular weight cut-offs (MWCO) were investigated. The effects of the molecular weights (MW) of humic acids and pre-treatment with PAC on membrane fouling were studied. It was found that the hydraulic resistance caused by fouling materials calculate

Eleven aromatic pesticides were used for a removal study using a 4040 spiral-wound polyamide nanofiltration (NF) membrane. The influences of molecular weight, molecular size (length and width), flux, and recovery were studied. The molecular weights of these pesticides are from 198 Da to 286 Da. Mole
