Hybrid Adsorption–Microfiltration Process for the Pretreatment of Sulfide-Containing Seawater: A Promising Strategy to Mitigate Membrane Fouling

Membranes
The presence of dissolved sulfides in feed seawater causes severe elemental sulfur fouling in the reverse osmosis (RO) process. However, current pretreatment methods suffer from large footprint, high energy consumption, and limitations in effluent ...

Influence of composite admixtures on the freezing resistance and pore structure characteristics of cemented sand and gravel

Materiales de Construccion, 2022
CSG shows low freezing resistance due to its poor cementing properties, and adding admixtures is the main method to improve its freezing resistance. In this paper, experiments were designed based on the Taguchi method and on the freezing resistance and ...

Valuable elements in sludge from eight municipal wastewater treatment plants in relation to their recovery potential

Environmental Sciences Europe
Background The management of sludge from municipal wastewater treatment plants (WWTPs) is a global issue, but also an opportunity for circular reuse. Recent data show that sludge reuse in agriculture has the highest share of all utilization routes in the

Aminophosphonates in Nanofiltration and Reverse Osmosis Permeates

Membranes, 2021
Aminophosphonates such as aminotris(methylenephosphonic acid) (ATMP) are common constituents of antiscalants. In nanofiltration (NF) and reverse osmosis (RO) processes, ATMP prevents inorganic scaling leading to more stable membrane performance.
