During the washing and beneficiation of coal or any minerals, particulates become suspended in waste water. Before reuse of these discharged waters, suspended particulates and various contaminants must be removed from this effluent. Coal washery consume huge amount of water and hence generates huge amount of waste water. If this water is directly discharged into streams, it will cause environmental pollution. Coal washery effluents contain high amount of suspended particles, has high turbidity… Expand

Characterisation of coal washery effluent and optimisation of coagulation behaviour of Moringa oleifera seed as a coagulant
TLDR
This study deals with detailed characterisation of coal washery effluent and fine particles present in it and the suitability of biocoag-flocculation process using Moringa oleifera seed biomass as a natural coagulant was examined for efficient removal of impurities. Expand
Revolutionary technique for sustainable plant-based green coagulants in industrial wastewater treatment—A review
Abstract Chemical coagulants have been extensively used in wastewater treatment from industrial processes due to their removal efficiencies. Notwithstanding, recent studies have reported concernsExpand
Use of natural coagulants for industrial wastewater treatment.
Industrial effluents are a menace to the environment and the fact that their characteristics vary from industry-to-industry only adds to the complex challenge they offer to the engineers andExpand
