⚡️Detection Methods
1- Current Techniques: Traditional methods for detecting microplastics in water typically identify particles as small as 10-20 micrometers. However, research indicates that microplastics can be smaller, potentially leading to significant underreporting of their presence. Various detection methods include:
2- Fourier Transform Infrared (FT-IR) Spectroscopy: This method can detect microplastics down to approximately 20 μm and is widely used for identifying the composition of plastic particles.
3- Raman Spectroscopy: Capable of identifying even smaller particles (down to 1 μm), this technique is more expensive and time-consuming but provides detailed compositional analysis.
4- Simple Filtration and Centrifugation: These methods are cost-effective and easy to implement but may struggle with accurately separating microplastics from other materials.

⚡️Challenges:
The lack of uniformity in microplastic sizes and types complicates detection efforts. Current technologies may miss smaller particles, which could be more toxic than larger ones. Additionally, some treatment processes may inadvertently cycle larger microplastics through systems, breaking them down into smaller sizes that escape removal.

⚡️Removal Efficiency in Wastewater Treatment Plants (WWTPs)
Research shows that while WWTPs can remove over 99% of detectable microplastics, effluent still contains significant amounts. For instance, a study found influent concentrations ranging from 520 to 1820 particles/L, with effluent concentrations between 0.56 to 2.34 particles/L. The primary removal mechanisms occur during secondary clarifications and tertiary treatments. However, the types of treatment technologies employed did not significantly affect removal rates.

⚡️Applications:
1- Wastewater Treatment: Identifying effluent microplastics helps optimize removal techniques before discharge into water bodies.
2- Drinking Water Purification: Ensures the removal of microplastics from municipal water supplies to safeguard public health.

The Microplastic Detection market is expected to reach USD 6.49 billion by 2029, growing at a 6.4% CAGR. Key drivers include rising environmental concerns and regulations, with top regional players in North America, Europe, and Asia-Pacific driving growth.
