The aim of data article was to evaluate effectiveness of the combined process of coagulation, flocculation and filtration to remove reactive black 19 from solution aqueous. In this data article, alum and ferric chloride were selected as a coagulant for instability of color before ceramic membrane. All experiments were performed in batch conditions. The results showed that more than half of the ceramic membrane is made of silica. The BET surface area of the ceramic membrane was 1.877 m g. The size of RB19, alum, and ferric chloride was 996.2 mm, 1216 mm, and 86.26 mm, respectively. Also, the zeta potential of RB19, alum, and ferric chloride was 20.7 mV, 1.59 mV, and 34.7 mV, respectively. The findings showed that the best pH to remove the RB 19 by alum and ferric chloride was less than 7. With increasing concentrations of alum and chlorine ferric the removal of RB 19 increased. For RB19 concentration of 10 mg l, with increasing time from 5 to 15 min, the removal efficiency for alum and ferric were 61-63% and 82-87%, respectively.
本数据文章的目的是评估混凝、絮凝和过滤联合工艺从水溶液中去除活性黑19的效果。在本数据文章中,由于陶瓷膜之前颜色不稳定,选择明矾和氯化铁作为混凝剂。所有实验均在间歇条件下进行。结果表明,超过一半的陶瓷膜由二氧化硅制成。陶瓷膜的BET表面积为1.877 m²/g。活性黑19、明矾和氯化铁的粒径分别为996.2 nm、1216 nm和86.26 nm。此外,活性黑19、明矾和氯化铁的zeta电位分别为20.7 mV、1.59 mV和34.7 mV。研究结果表明,用明矾和氯化铁去除活性黑19的最佳pH值小于7。随着明矾和氯化铁浓度的增加,活性黑19的去除率提高。对于10 mg/L的活性黑19浓度,随着时间从5分钟增加到15分钟,明矾和氯化铁的去除效率分别为61 - 63%和82 - 87%。
