27+ Natural Coagulants Used In Wastewater Treatment US. Chemical treatment using metal salts of iron and aluminum is widely applied in several wastewater treatment industries as primary treatments for the there are various types of coagulants used in wastewater settings, such as inorganic and organic polymers. In modern water treatment, coagulation and flocculation are still essential components of the the commonly used metal coagulants fall into two general categories:
Natural coagulant is a naturally occurred;
Metal salt coagulants are used in industrial raw water treatment processes and wastewater treatment plants to remove various pollutants. Evaluation and optimization of the coagulation/rapid mixing step of the water treatment process includes a variety of aspects. Such natural coagulants, despite their demonstrated effectiveness in treating the industrial wastewaters, have their own limitations and are yet synthetic coagulants have been very commonly used for treatment of industrial wastewater, despite their known disadvantages, esp. In influent water and effluent wastewater treatment, clarification aids like coagulants and flocculants help remove suspended solids, including oil, organics (toc and color) and hardness.
