| Περίληψη: | To address the challenges in sewer systems where continuous wastewater flow renders conventional iron salt dosing ineffective for long-term control, and where iron salts cause a sharp pH decline and structural weakening of pipelines, this study developed a coated sustained-release ferrous chloride granule (PMDI‑Fe2+). Under long‑term operation of laboratory‑scale reactors, the results showed that at a PMDI‑Fe2+ dosage of 0.045 % (w/v), the half‑maximal recovery time (RT (Copyright © 2026 Elsevier Ltd.
