Batch and column studies on removal of methylene blue basic magenta and eriochrome black t dye by microalgae biochar

Abstract

The current rate of industrialization produces numerous negative consequences that must be addressed. One of these repercussions is the destruction of water bodies in the neighbourhood of the industry. As a result, wastewater that is released into bodies of water or on land must be treated first to eliminate any pollutants that could harm the environment, aquatic life, or humans. Water contamination is increased by a variety of factors, including industrialisation, urbanisation, and population growth. To address this issue, the government and industry are taking many steps to use water rather than dispose of it in adjacent bodies of water. One of these is wastewater recycling to produce clean water or water that is regarded to be free of harmful or hard elements. As a result, more efficient methods are being created and tested on a laboratory scale for their efficacy. Among all of the contaminants, dye molecules scattered in the water medium are the most difficult to remove. The chemical and physical properties of water are affected by its nature. As a result, proper ways for making wastewater produced by the textile industry fit for contact with the environment are being developed. newline
