Pressure retarded osmosis (PRO) has the potential to produce clean, renewable energy from natural salinity gradients. However, membrane fouling can lead to diminished water flux productivity, thus reducing the extractable energy. This study investigates organic fouling and osmotic backwash cleaning in PRO and the resulting impact on projected power generation. Fabricated thin-film composite mem...

Ulcerative colitis (UC) is a form of inflammatory bowel disease that typically involves the colorectum; it has been reported that a certain proportion of patients with UC also develop ileitis, leading to ileal perforation in very extreme cases. We report a 66-year-old male with UC who presented with ileal perforation eight days after proctocolectomy. Although this situation is very rare, differ...

Based on a “filter press backwash–chemical precipitation–gaseous membrane absorption” process, treatment of harmless cyanide tailings was conducted using from gold smelting enterprises (Yunnan Province, China) as the research object. The effects air-drying time, backwash water parameters, initial pH acidification, NaHS dosage, cyanide-containing flow rate, and gaseous stages process were invest...

• UF coagulant dose controller was successfully developed and field tested. • Self-adaptive in-line UF coagulant dosing reduced coagulant consumption. • Real-time tracking of fouling resistance and backwash effectiveness. • Robust UF operation during conditions of deteriorating source water quality. ⁎ Corresponding authors.
