Objective:

The overall objective of this study is to investigate the potential use of macroalgae for removal of dyes from industrial water effluent, specifically from textile industries. We proposed a novel solution to treat textile water effluents containing reactive dyes that pose significant problems by using macroalgae as a biosorption media. In this study we proposed to investigate the biosorption capacities of brown macroalgae species Sargassum for dye removal from simulated textile water effluent streams in batch and continuous adsorption columns.

Description:

Developing low cost biobased technologies that enable water reuse and simultaneously reduce energy consumption in the water treatment is a critical need. In this context, textile industries are known for their heavy water use and polluting discharge into communal waters. One of the chief hurdles in large scale treatment of the textile industry effluents is the high capital and operating cost of treatment technologies.

Implementing this low cost technology in developing countries can positively impact people by reducing the water pollution, improve their prosperity by generating additional jobs for macro algae production and reducing the cost of operation for the textile industries and impact the planet by reducing the environmental impact of textile industries which have significant water and energy footprint. The P3 project will educate the industry by demonstrating the low cost algae as alternative to treat textile waste water and why this technology should be implemented in their industry.

Conclusions:

It was determined that the column treatment scheme as originally proposed may not be feasible since the there is no significant difference in the adsorption of the dye based on the media or the media pH. These results were used to formulate a novel scheme in phase II grant that addresses this issue.
