Application and mechanistic study of compound flocculants in coal slime wastewater treatment
Desalination and Water TreatmentCoal slime water generated during coal washing contains abundant ultrafine suspended particles with high surface charge and strong colloidal stability, making efficient clarification difficult using single-component flocculants.

Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Background Soil fertility management in mango and banana production systems in northern Peru is limited by marked spatial heterogeneity, driven by chemical imbalances, particularly salinity, alkalinity, and sodicity. Aim This study developed a spatial predictive framework to assess soil quality across the agricultural area of Morropón Province,

Environmental Toxicology, EarlyView.ABSTRACT This study assessed the ecotoxicological effects of treated sewage on the freshwater planarian Girardia tigrina, integrating biochemical, energetic, and behavioral biomarkers. Planarians were exposed for 48 h to different concentrations of treated sewage (12.5%, 25%, 50%, and 100%) and compared to controls using commercial water and water from

Adsorption of Phosphonates to Iron- or Aluminum-Based Flocculants in Wastewater Treatment
WaterIn this study, we investigated the impact of varying iron (Fe) and aluminum (Al) contents on the adsorption of phosphonates to activated sludge. Phosphonates originating from household applications account for up to 40% of the non-reactive dissolved phosphorus in domestic sewage treatment plants and thus can contribute to the eutrophication of water ...

Separation of dark-colored minerals from feldspar by selective flocculation using starch
, 2004 Feldspar ores usually contain some amounts of impurity dark-colored minerals (DCM), rich in iron. Such ores must be comminuted for the liberation and separation of the said impurities.

Selected Physical and Geotechnical Properties of Loess in Wairarapa Valley, New Zealand
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.Loess up to 10 m thick covers marine terraces, old river aggradation terraces, and gentle hill country slopes in Wairarapa, New Zealand. In the drier eastern and southern parts of Wairarapa, the loess is subject to dry summer and autumn and wet winter and spring in most years.
