The ability of a commercial tannin-based coagulant on the decolorization simulated textile effluent containing reactive dye was studied in batch mode. For comparison, two conventional chemical coagulants (aluminum sulfate and Rifloc 6548-organic coagulant) were also tested. Preliminary assays suggested higher performance Tanfloc SG over metal salt. Optimization conducted for SG, indicated maxim...

Inorganic aluminum ions, [Al(H2O)6]3+, [Al(OH)(H2O)5]2+, and [Al(OH)2(H2O)4]+, are toxic to a number of crops. The aim of this study was to estimate the danger of soil contamination of bioavailable aluminum and heavy metals forms because of alum sludge which was a by-product of water, and wastewater treatment technology using aluminum coagulant is introduced into the soil. Aluminum and selected...

Polysaccharides possess the highest industrial capacity for adsorbents that can be useful as eco-friendly materials for water treatment, due to their prevalence [1–3]. Polysaccharides are stereoregular (natural) polymers of monosaccharides (sugars) also referred to as biopolymers. They are unique raw materials because they are inexpensive and widely available in many countries in the world. The...

The plastic recycling industry generates a high volume of wastewaters. In this study, an unprecedented use Moringa oleifera and tannin (Acacia mearnsii bark) associated with magnetite was proposed for the treatment these response surface method (RSM) central composite rotational design (CCRD) methodology applied to optimize influence operational variables (pH, temperature, electrical conductivi...
