Notice of Retraction: Study on composite flocculation to treat mine water containing Zn²⁺

Abstract

According to the characteristics of mine water from Tongkeng, the heavy metal Zn 2+ ions in wastewater will be removed by composite flocculation. Through the experimental study on composite flocculation factors, containing drug types, drug ratio, drug time, pH value, stir time and stir intensity, analyzed the factors on the Zn 2+ ions removal effect in wastewater treatment. The results show that through experimental parameters optimization, the removal rate can achieve 97% by the application of composite flocculation to treat mine water with Zn 2+ ions. The effluent quality can satisfy national integrated wastewater discharge standard requirement.

Studies of membrane fouling mechanisms involved in the micellar-enhanced ultrafiltration using blocking models

“…MEUF measurements were carried out at 20 °C using a flat sheet module supplied by Xiamen Tianquanxin Membrane Technology Co, Ltd., China, which was presented in our previous study 26 . The feed wastewater was made by adding the pre-determined amount of phenol and surfactant into deionized water and then was mixed adequately to make sure that the solutes evenly dispersed before entering the membrane module.…”
