Is Micro Plastic Filtered at Waste Water Treatment Plant?

Microplastics are tiny plastic particles that measure less than 5mm in diameter. These particles come from various sources such as cosmetics, clothing, and plastic bags, and they ultimately end up in water bodies. In response to the increasing concern about the negative impact of microplastics on the environment, several governments and organizations have initiated efforts to eliminate these particles. One common question that arises is whether waste water treatment plants filter out microplastics in water?

The Role of Waste Water Treatment Plants

Waste water treatment plants (WWTPs) play a vital role in treating sewage and wastewater, making sure that it is safe to discharge into waterways. The process involves different stages of treatment aimed at eliminating solids, organic matter, and chemicals. The primary steps of WWTPs include screening, sedimentation, and biological treatment. One question that arises is whether microplastics are filtered out of the water in the purification process.

The Limitations of Waste Treatment Plants

It is important to note that while WWTPs are effective in removing larger pieces of plastics, microplastics are too small to be filtered effectively with current technology. The microplastics that pass through treatment plants are discharged in the treated water, making their way into rivers, sea, and groundwater.

Microplastics are very lightweight and can adhere to other organic materials resulting in secondary pollution. In the oceans, for instance, plastic waste can accumulate on the surface of the sea, leading to the forming of islands of waste in specific areas.

The Harms of Microplastic Pollution

Microplastic particles pose a great threat to the environment since they are absorbed into living organisms such as fish, birds, and other aquatic creatures. As creatures feed on contaminated materials, the particles accumulate in their tissue, leading to health issues such as inflammation and immune system dysfunction. The impact of microplastics is felt beyond marine life as they can pose an indirect threat to human health. Studies show that the chemicals used in the production of plastic can harm human health when ingested through seafood consumption or drinking water containing traces of microplastics.

Conclusion

In conclusion, microplastics are not filtered out in the current treatment processes carried out by WWTPs. However, some organizations and governments are currently researching ways to eliminate microplastics during the wastewater purification process. Prevention is also key in addressing the issue of microplastics by reducing plastic waste and promoting recycling efforts.
