TL;DR: Comparison with the performance of the centralized plant treating the same wastewater has showed that SBBGR system is able to produce an effluent of comparable quality with a simpler treatment scheme, a much lower hydraulic residence time and a lower sludge production.

TL;DR: In this paper, a sequencing batch biofilter granular reactor was tested at laboratory scale for treating a printing wastewater characterized by high concentrations of surfactants and nitrogen, and the results have shown that the process assured the possibility to comply with the limits for direct discharge for all investigated parameters by operating at an organic load value lower than 1.5 kgCOD/m3d and with an ozone dose of 135 mg/l.

TL;DR: In this article, the sequencing batch biofilter granular reactor (SBBGR) was used for dyeing textile wastewater before discharge into municipal sewer system, and the results demonstrated that good treatment efficiencies can be achieved even at high organic load values (2.4-2.6 kg COD ) and with hydraulic retention times lower than one day.

TL;DR: In this paper, the results obtained at laboratory, pilot and demonstrative scale with granular activated carbon adsorption as a mean to obtain effluent suitable as water supply for textile finishing industries, that require very stringent limits in terms of COD and colour removal.

TL;DR: Results have demonstrated that mixed wastewater can be successfully treated with very low hydraulic retention times (less than 10 hours), and SBBGR shows to be an effective pre-treatment for textile wastewater for discharge into sewer systems.
