Treatment of tannery wastewater by chemical coagulation
TL;DR: In this paper, the influence of pH and coagulant dosages on the coagulation process was studied and conditions were optimised corresponding to the best removal of organic matters, suspended solids as well as chromium.
Journal ArticleDOI
Sedimentation of tannery wastewater
TL;DR: In this paper, the authors investigated the pretreatment of a tannery wastewater, typified by the mixed effluent from tannery operations, and demonstrated 41.5% removal of total chemical oxygen demand (COD), 83.2% of chromium and 76.1% of suspended solid after 3h of plain settling.

Biodegradation of tannery wastewater using sequencing batch reactor--respirometric assessment.
TL;DR: This investigation proved that respirometry combined with sequencing batch reactor (SBR) could be an effective way for the removal of COD in tannery wastewater and simultaneous nitrification-denitrification was observed in the SBR during the feed period.
Journal ArticleDOI
COD fractionation of tannery wastewaters--particle size distribution, biodegradability and modeling.
TL;DR: Model-based evaluation of the THE AUTHORS' profiles enabled quantifying the impact of inhibition in terms of changes in rate coefficients for growth, hydrolysis of soluble COD and endogenous decay, and a very slowly biodegradable/residual particulate COD component with a significant inhibitory effect.

Wastewater control and management in a leather tanning district
TL;DR: In this paper, an initial assessment of industrial structure and wastewater characteristics is important for successful environmental management in an industrial district, particularly for the cases where highly polluting industries such as leather tanners are of concern.
