This study illustrates the efficiency of microalgae-based treatment system for the bioremediation of Yamuna water. Organic and Inorganic substances that are released into the water because of domestic, agricultural and industrial activities leads to heavy pollution of rivers. Many times it becomes inconvenient that this pollution cannot be treated by primary and secondary treatment process. In such cases, the tertiary treatment becomes necessary for remediation of river water. Microalgae are one of the effective agents to carry out the tertiary treatment. Microalgae grow by using their necessary nutrients from the wastewater by absorption leading to tertiary water treatment and finally produce biomass of great worth. In the present study, we checked all the physicochemical parameters like pH, dissolved oxygen (DO), biological oxygen demand (BOD) and chemical oxygen demand (COD) during our 20 days of study and observed a significant change in all these parameters, specifically ~37% reduction in both Biological oxygen demand and Chemical oxygen demand was achieved while the DO was increased by 116% during study.

使用藻类对亚穆纳水进行生物修复

这项研究说明了基于微藻的处理系统对Yamuna水的生物修复的效率。由于家庭，农业和工业活动而释放到水中的有机和无机物质导致河流严重污染。很多时候，这种污染不能通过一级和二级处理过程进行处理变得很不便。在这种情况下，必须进行三级处理以修复河水。微藻是进行第三级治疗的有效试剂之一。微藻通过利用废水中的必需养分进行吸收而生长，从而导致进行第三级水处理，并最终产生有价值的生物质。在本研究中，我们检查了所有物理化学参数，例如pH，溶解氧（DO），
