REVIEW ON REMIDIATION OF MICRO-PLASTICS FROM WATER

Shivu H A, Vaishnavi B R, Nagrajswamy ., Vikas Sanjeev, Dr. Deepthi B P

Abstract


Microplastics (MP) have been identified in both drinking water and raw water, with their introduction into the environment occurring through various human activities in homes, workplaces,  and  sewa3ge  systems.  The  discharge  of  microplastics  into  the  environment  is

facilitated by factors such as the diminutive size of these particles, preventing their efficient

removal from drains, and the presence of synthetic microplastic fibers in skincare products, which persist in the environment.

 

In a single laundry cycle, synthetic fabrics release around 700,000 microplastic fibers, contributing further to the prevalence of microplastics in water sources. Additionally, the utilization of materials in industrial applications as raw ingredients for plastic products can result in the release of microplastics into the environment. Consequently, understanding the efficacy of drinking water systems in eliminating microplastics becomes crucial.

 

The Rapid Sand Filter (RSF) emerges as a potential water purification method that could serve as an alternative treatment to effectively remove microplastics post various treatments. While RSFs are recognized as wastewater treatment devices that are generally effective in microplastic removal, there remains a gap in research regarding the exclusive efficiency of RSFs in eliminating microplastics.

 

Another promising avenue for microplastic removal involves the use of biochar, a carbon-rich substance formed through the thermal decomposition of biomass under anoxic conditions. Studies have demonstrated the efficacy of biochar in extracting microplastics from water sources. Therefore, exploring the combined or individual potential of Rapid Sand Filters and biochar in addressing the issue of microplastics in water systems is imperative for devising effective water treatment strategies
