Abstract

The paper studies the effect of the vibration on the flotation processes for microplastic particles (polymer particles <5 mm in diameter). In recent years, the world community is facing the problem of water pollution with microplastics, which is a fundamentally new type of the particles in marine environment that has specific hydrodynamic characteristics and impairs the efficiency of existing water treatment processes. In this paper, the authors compared the classical process of pneumatic flotation with the process of pneumatic flotation with vibroacoustic effect and the positive effect of vibration influence on the efficiency of the flotation of water microplastics is shown.

Highlights

Plastic pollution is a priority problem, which has received increasing attention in the last decade [1]
Microplastics are generally defined as solid synthetic polymer particles with a characteristic particle size of fewer than 5 millimetres, with low water solubility and a low degradation rate
Wastewater treatment plants are one of the main sources of microplastics discharge into water environments

Summary

Introduction

Plastic pollution is a priority problem, which has received increasing attention in the last decade [1]. Plastic products can slowly disintegrate into smaller pieces and, due to their low density, are dispersed by ocean currents and winds over aquatic and coastal environments [2]. These small polymer particles are called microplastics. The World Health Organization currently does not recognize microplastics itself as a direct hazard to the human body, and as a result, does not establish standards for its content in drinking water This decision is based on studies of physical harm to the tissues of living organisms during physical interaction with microplastic particles [11]. Based on the above and taking into account the durability of microplastics and their ability to travel along the food chain, the frequency of their occurrence in the aquatic environment is a global problem
