Several studies have focused in the tannery industry due to the high polluting potential of the effluent generated in leather processing; high concentrations of total chromium and organic load. However, the high costs attributed to the treatment of tanning residues explains why this material is not treated within the tannery industry. The extract from the flower of Musa sp, condensed and hydrolisable tanins, yet to be explored in literature was applied to remove organic matter from chemically enhanced primary treatment (CEPT) of total solids, turbidity and total chromium from a tanning industry and leather processing. The use of the flower extract of Musa sp. proposed in this study does not require flocculant polymers after the coagulation step. A central composite design response surface (CCD) was modelled by the factors: coagulant volume, pH and rotation. The optimization was performed according to the NBI algorithm in a mixed arrangement to determine optimal weights. The modeling from CCD and minimization of Global Standard Error determines the optimized conditions, turbidity removal, total cromium, hexavalent chromium and trivalente chromium of 78% and 65.4%, 39.43% and 61.02%, respectively, increasing the biodegradability from the ratio biochemical oxygen demand (COD) and chemical oxygen demand (COD) of 0.12–0.63.

由于皮革加工过程中产生的废水具有高污染潜能，因此有几项研究集中在制革业。高浓度的总铬和有机负荷。但是，归因于鞣制残留物处理的高昂成本解释了为何在制革工业中不对这种材料进行处理。芭蕉科花的提取物，缩合和可水解的单宁酸（尚未在文献中进行探讨）已被用于从鞣革行业和皮革加工过程中对总固体，浊度和总铬的化学强化一级处理（CEPT）中去除有机物。穆萨花的花提取物的用途。本研究中建议的絮凝步骤后不需要絮凝剂聚合物。通过以下因素对中央复合设计响应表面（CCD）进行建模：凝结剂体积，pH和旋转。根据NBI算法以混合方式执行优化，以确定最佳权重。CCD建模和最小化全球标准误差确定了最佳条件，浊度去除，总铬，六价铬和三价铬分别为78％和65.4％，39.43％和61.02％，
