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.

Size distribution of wastewater COD fractions as an index for biodegradability.
TL;DR: Direct particle size measurement by sequential filtration and ultrafiltration as a convenient method for wastewater characterization for appropriate treatment technology and the correlation between particle size distribution (PSD) and chemical oxygen demand (COD) fractionation, as an index for biological treatability are proposed.

TL;DR: An assessment was made of cheese whey treatment in a mechanically stirred anaerobic sequencing batch reactor (ASBR) containing granular biomass and showed formation of viscous polymer-like substances, probably of microbiological origin occurring mainly at influent CODs of 2000 and 4000 mg/L and caused some biomass flotation.

Modelling of activated sludge for textile wastewaters
TL;DR: In this paper, a comprehensive evaluation of four different textile wastewaters was carried out to set the experimental basis for the modelling of activated sludge process, and experiments involved beside conventional characterization, detailed COD fractionation and assessment of major kinetic and stoichiometric coefficients by means of respirometric measurements.
