Aquatic algal communities demonstrated their appeal for diverse industrial applications due to their vast availability, ease of harvest, lower production costs, and ability to biosynthesize valuable molecules. Algal biomass is promising because it can multiply in water and on land. Integrated algal systems have a significant advantage in wastewater treatment due to their ability to use phosphorus and nitrogen, simultaneously accumulating heavy metals and toxic substances. Several species of microalgae have adapted to thrive in these harsh environmental circumstances. The potential of algal communities contributes to achieving the United Nations' sustainable development goals in improving aquaculture, combating climate change, reducing carbon dioxide (CO) emissions, and providing biomass as a biofuel feedstock. Algal-based biomass processing technology facilitates the development of a circular bio-economy that is both commercially and ecologically viable. An integrated bio-refinery process featuring zero waste discharge could be a sustainable solution. In the current review, we will highlight wastewater management by algal species. In addition, designing and optimizing algal bioreactors for wastewater treatment have also been incorporated.
水藻群落由于其广泛的可用性、易于收获、较低的生产成本以及生物合成有价值分子的能力，展示了其在各种工业应用中的吸引力。藻类生物量很有前途，因为它可以在水和陆地上繁殖。由于能够利用磷和氮，同时积累重金属和有毒物质，藻类综合系统在废水处理方面具有显著优势。一些微藻物种已经适应了这些恶劣的环境条件，茁壮成长。藻类群落的潜力有助于实现联合国在改善水产养殖、应对气候变化、减少二氧化碳（CO）排放以及提供生物质作为生物燃料原料方面的可持续发展目标。基于藻类的生物质加工技术促进了商业和生态上可行的循环生物经济的发展。零废物排放的综合生物精炼工艺可能是一种可持续的解决方案。在本次综述中，我们将重点介绍藻类物种对废水的管理。此外，还纳入了用于废水处理的藻类生物反应器的设计和优化。
