The presence of nanoplastics in wastewater streams has emerged as an environmental concern, necessitating the development of efficient removal methods. This scientific communication aims to explore the use of total suspended solids (TSS) as a metric for nanoplastic removal and discusses the optimal sizing of goch pads (pursuant to suspended solids lab procedure}


Lab equipment required includes:


  1. A grab sample,

  2. 50ml beaker, vacuum pump for filtration,

  3. Desiccator

  4. Muffle furnace and a

  5. Scale with apparatus with wind breaker (highly sensitive and precise). You will need a scale that uses data connectivity with a computer to process the data and eliminate interferences. capable of measuring picograms or atomic mass unit.


Further requirements are effective coagulants for plastics, existing precedents in nanoplastic removal, and the potential use of polymers in secondary clarifiers to enhance nanoplastic removal efficiency. The objective is to provide insights into achieving the best possible percent removal of nanoplastics based on current technological thresholds.

The accumulation of nanoplastics in wastewater poses significant challenges to both environmental and human health. This article highlights the importance of employing TSS as a metric to quantify nanoplastic concentrations in wastewater streams and emphasizes the need for efficient removal methods. By optimizing the nanoplastic removal process, the article aims to contribute to the development of sustainable wastewater treatment practices.


Accurate sizing of goch pads is crucial for effective nanoplastic capture. To achieve optimal removal efficiency, factors such as wastewater flow rate, nanoplastic concentration, and desired removal percentage must be considered. This section discusses the importance of surface area, pore size, and filtration capacity in determining the appropriate size of goch pads, ensuring efficient nanoplastic capture.

Selecting suitable coagulants for nanoplastic removal presents unique challenges due to the inherent resistance of plastics. However, recent advancements have shown promise in the utilization of coagulants such as polyaluminum chloride (PAC), ferric chloride, and polyacrylamide (PAM) for destabilizing nanoplastic suspensions and facilitating their removal through sedimentation or filtration processes. Note that plastics are non reactive unlike organic materials, and without charges there ability to flocculate materials are limited.


In smaller scale "point of use" privately potable water treatment the use of activated polyethyleneimine resin has been definitively proven to remove micro and nanoplastics from water streams. This is professionally installed similarly to a water softening unit. Further treating a few hundred gallons per day for "whole house" microplastics removal can be accomplished for under three thousand U.S dollars. Further, to removal micro and nanoplastics from drinking water at the kitchen sink a decent reverse osmosis system will suffice.



This section explores the effectiveness of these coagulants in achieving optimal nanoplastic removal.

Precedents for Nanoplastic Removal:


While the field of nanoplastic removal is relatively nascent, there are notable precedents that provide valuable insights into potential strategies. This section examines existing precedents in the removal of microplastics from wastewater using membrane filtration, activated carbon, and advanced oxidation processes. These precedents serve as a foundation for the development of effective nanoplastic removal techniques utilizing TSS as a metric.


Enhancing Nanoplastic Removal in Secondary Clarifiers:

Secondary clarifiers play a critical role in wastewater treatment plants by separating suspended solids from treated water. This section explores the potential of using polymers, such as polyacrylamide, in secondary clarifiers to enhance nanoplastic removal efficiency. By optimizing polymer dosage and application, it is possible to improve flocculation and achieve higher percentages of nanoplastic removal.


The utilization of TSS as a metric for nanoplastic removal in wastewater streams holds significant promise for achieving optimal removal efficiencies. This scientific communication emphasizes the importance of precise goch pad sizing, suitable coagulants for plastics, and the exploration of precedents in microplastic removal techniques. Additionally, it highlights the potential of using polymers in secondary clarifiers to enhance nanoplastic removal percentages. By considering these factors and leveraging current technological thresholds, it is possible to advance the field of nanoplastic removal and contribute to sustainable wastewater treatment practices.
