TL;DR: In this article, a CuO coated ceramic hollow fiber membrane with dual functionalities of membrane filtration and peroxymonosulfate (PMS) activation was successfully constructed by applying phase-inversion and dip-coating technologies.

TL;DR: This study investigates the reactivity of cuprous oxide for activating peroxymonosulfate (PMS) to decompose diverse organic contaminants and provides new insights into the copper-catalyzed AOPs and vital supplementary to the ongoing dialogue of the nonradical catalysis in persulfate-based oxidation.

TL;DR: In this article, a hollow flat ceramic membrane MBR reaction tank and a membrane cleaning method was provided for the technical field of sewage treatment, and the authors proposed a method to achieve degradation and damage of dirt through ozone in a backwashing solution, separation of dirt and membrane material can be promoted through the disturbance effect of water flow, and an ozone generation device is further arranged outside the reaction tank.

TL;DR: In this article, an MBR sewage treatment device consisting of a reaction tank, wherein a partition plate is arranged in the reaction tank and divides the reaction box into a first area and a second area, gaps are formed between the two ends of the partition plate and the reaction bowl, sewage in the first and second areas form circular flow through the gaps at two ends.

TL;DR: In this article, a method for the preparation of a multichannel hollow flat ceramic membrane is presented. But the method is not suitable for the manufacturing of a large number of channels.
