摘要: This review presents the extractions, characterisations, applications and economic analyses of natural coagulant in separating pollutants microalgae from water medium, known as harvesting. The promising future a next-generation energy source is reviewed significant drawbacks conventional harvesting using alum are evaluated. performances studied proven to exceed alum. In addition, details each processing stage extraction (plant, microbial animal) comprehensively discussed with justifications. information could contribute exploration novel coagulants by providing description optimised steps for number coagulants. Besides, characterisations have garnered great deal attention, strategies enhance flocculating activity based on their characteristics discussed. Several important been tabulated this such physical aspects, including surface morphology charges; chemical molecular weight, functional group elemental properties; thermal stability parameters thermogravimetry analysis differential scanning calorimetry. Furthermore, various industries other than revealed. cost application mass allowed evaluate its feasibility towards commercialisation industrial. Last, potentially new coagulants, which yet be exploited applied, listed additional study.
