The pollutants can enter water bodies at various point and non-point sources, and wastewater discharge remains a major pathway. Wastewater treatment effectively reduces contaminants, it is expensive and requires an eco-friendly and sustainable alternative approach to reduce treatment costs. Algae have recently emerged as a potentially cost-effective method to remediate toxic pollutants through the mechanism of biosorption, bioaccumulation, and intracellular degradation. Hence, before discharging the wastewater into the natural environment better solutions for environmental resource recovery and sustainable developments can be applied. More importantly, algae are a potential feedstock material for various industrial applications such as biofuel production. Currently, researchers are developing algae as a source for pharmaceuticals, biofuels, food additives, and bio-fertilizers. This review mainly focused on the potential of algae and their specific mechanisms involved in wastewater treatment and energy recovery systems leading to important industrial precursors. The review is highly beneficial for scientists, wastewater treatment plant operators, freshwater managers, and industrial communities to support the sustainable development of natural resources.
污染物可以通过各种点源和非点源进入水体,而废水排放仍然是主要的途径。废水处理可以有效地减少污染物,但成本高昂,需要一种环保且可持续的替代方法来降低处理成本。藻类最近成为一种通过生物吸附、生物积累和细胞内降解机制修复有毒污染物的具有成本效益的方法。因此,在将废水排放到自然环境之前,可以应用更好的环境资源回收和可持续发展的解决方案。更重要的是,藻类是各种工业应用的潜在原料,如生物燃料生产。目前,研究人员正在将藻类开发为药物、生物燃料、食品添加剂和生物肥料的来源。本综述主要集中于藻类的潜力及其在废水处理和能源回收系统中的具体机制,这些系统可带来重要的工业前体。该综述对科学家、废水处理厂运营商、淡水管理者和工业界非常有益,有助于支持自然资源的可持续发展。
