Water has been one of the human life's most significant commodities. Due to increasing price toxic coagulants and method water treatment, rural people live in serious poverty use untreated drink. The best solution for problems described above is a plant-based coagulant instead chemical coagulant. Coagulants made from plants are used Mung beans, peanut seeds, coconut tree cactus, example, have m...

Abstract Wastewater issues became a complex challenge in the world. There are several methods wastewater treatment, such as chemical, physical, biological, and combination of each method. However, process has advantages disadvantages. The physicochemical common used adsorption coagulation. Adsorption coagulation excellent to remove pollutants. is greatly influenced by pH, adsorbent dose, temper...

Tannins are natural polyphenolic compounds widely found in plants. The production of coagulants for water treatment is one their new applications. Polyphenols extraction the first step synthesizing tannin-based coagulants. Eucalyptus globulus bark (EGB), an abundant by-product pulp and paper industry, usually applied as fuel energy production, was used this work a tannin source. polyphenols fro...

The ever-present environmental crises are current research hotspots. Nature-based solutions have been shown to multiple co-benefits toward solving these crises. Plant-based coagulants known be a cost-effective and environmentally friendly approach for coagulation flocculation processes drinking-water treatment. In this study, natural coagulant was extracted from Annona diversifolia seed, its ef...

Correlations between raw water characteristics and pH after enhanced coagulation to maximize dissolved organic matter (DOM) removal using four typical coagulants (FeCl3, Al2(SO4)3, polyaluminum chloride (PACl) and high performance polyaluminum chloride (HPAC)) without pH control were investigated. These correlations were analyzed on the basis of the raw water quality and the chemical and physic...

The aim of this study was to characterize landfill leachate of Çorlu that was heavily industrialized, and to examine the application of coagulation-flocculation and adsorption for the treatment of this leachate. This deposited area is non-regulated and municipal and industrial wastes are deposited uncontrollably. The experiments were conducted to investigate the combined process of coagulation-...
