Bio-flocculants produced by Bacillus sp. and Pseudomonas sp. were evaluated as flocculating agents for the removal of Cu (II), Pb (II) and Cd (II) from chemical and textile wastewater industries. Both bio-flocculants were very effective for removal of heavy metals at a dosage not exceeding 0.1 mg/ml. However, the removal efficiency of heavy metals was dependant on initial concentration and type of bio-flocculants. 84.0% of Cu²⁺ and 99.5% of Pb²⁺ were removed from industrial wastewater using Bacillus sp. Bio-flocculant resulting residual values of 28.5 and 1.13µg/l respectively in the treated effluent. Lower removal efficiencies of 70.4% for Cu²⁺ and 97.8% for Pb²⁺ occurred using Pseudomonas sp. bioflocculant. Nevertheless, Pseudomonas sp. bio-flocculant achieved a substantially higher removal efficiency of Cd²⁺ (93.5%) as compared to 72.9% using Bacillus sp. Based on these results bio-flocculants are considered as a viable alternative for the treatment of industrial wastewater containing heavy metals.

芽孢杆菌属产生的生物絮凝剂。和假单胞菌。被评估为絮凝剂，用于从化学和纺织废水工业中去除Cu（II），Pb（II）和Cd（II）。两种生物絮凝剂在去除重金属方面都非常有效，其剂量不超过0.1 mg / ml。然而，重金属的去除效率取决于初始浓度和生物絮凝剂的类型。使用Bacillus sp。从工业废水中去除了84.0％的Cu ²⁺和99.5％的Pb ²⁺ 。生物絮凝剂在处理后的废水中残留值分别为28.5和1.13µg / l。Cu ²⁺和Pb ^2+的去除效率分别为70.4％和97.8％发生使用假单胞菌sp。生物絮凝剂。尽管如此，假单胞菌属。与使用芽孢杆菌属的72.9％相比，生物絮凝剂对Cd ^2+的去除效率显着提高（93.5％）。基于这些结果，生物絮凝剂被认为是处理含有重金属的工业废水的可行替代方法。
