Abstract
The paper presents different physical-chemical treatment applications for textile effluents (i.e. one-single or mixed treatment stages as coagulation-flocculation, homogenous advanced oxidation with hydrogen peroxide as Fenton-like processes, sorption applied for different textile wastewaters followed by sedimentation and/or filtration). The efficiencies of textile wastewater treatments in terms of effluent quality, treatment degree, and optimal operating parameters (i.e. pH, concentration of chemical reagents and materials used, temperature, operating regime, and time) are discussed, together with some restrictions and recommendations. These data concerning different effluent treatments are useful to the environmental management staff but also to all employees that adopted an environmental attitude (EA) in all them behaviour. The concern of solving inside environmental problems (mainly focused on quality of final effluent discharge in aquatic receptor and/or treated effluent recycling), and acting into an ethical, legal and viable manner is necessary and obligatory in the present condition of fresh water deficit, pollution increasing of natural surface water resources, and its variety and/or complexity.
