TLDR
In this article, the authors investigated the group composition and MW distribution of soluble organics in effluents from successive biological and chemical treatment stages, and found that most of the organics fell within the high MW range.About:

Fluorescence excitation-emission matrix regional integration to quantify spectra for dissolved organic matter.
TL;DR: Aromatic carbon and the presence of specific aromatic compounds resulted in EEMs that aided in differentiating wastewater effluent DOM from drinking water DOM, and the highest cumulative EEM volume was observed for hydrophobic neutral DOM fractions.

A mini-review on membrane fouling
TL;DR: This mini-review paper identifies the major foulants and the principal membrane fouling mechanisms such as pore blocking, cake formation, concentration polarization, organic adsorption, inorganic precipitation and biological fouling.

A review of soluble microbial products (smp) in wastewater treatment systems
TL;DR: It is concluded that the knowledge regarding SMP is far from complete and that much work is still required to fully understand their contribution to the treatment process; some of these future research areas are outlined.
Journal ArticleDOI
Characterization of isolated fractions of dissolved organic matter from natural waters and a wastewater effluent
TL;DR: 1H NMR spectra revealed that the HyI fractions were almost devoid of aromatic protons and the aliphatic region featured more sharp signals than HA and FA fractions, indicating that HyI fraction were consisted of more simple compounds and less complex mixtures.
Journal ArticleDOI
Characterization of soluble organic matter of waste activated sludge before and after thermal pretreatment.
TL;DR: Digesters treating high Mw (>300 kDa) materials resulted in smaller biodegradation rate constants, k, indicating that microorganisms require a longer time to utilize high Mmw fractions which are most likely cell wall fragments and exopolymers.

TL;DR: Gel filtration profiles obtained from a variety of naturally colored waters indicate that color producing molecules are mostly in the apparent molecular weight range of 700-10,000 relative to dextrans as discussed by the authors.

TL;DR: The typical color of surface waters is waters, lakes, and rivers contain organic between 5 and 200 color units (CU) as discussed by the authors, and drinking water standards permit up to 5 color and for taste and odor.
