Abstract

Biosorption Capacity of Activated Sludge Sand Bed for Removal of Copper from Treated Wastewater

Highlights

  • The progressive increase in industrialization and human activities translates into an increase in the percentage of waste accumulation worldwide and its release into the environment

  • In the following days of the experiment, a gradual decrease in the removal efficiency of Cu ions from wastewater flowing into the bed was observed, which was close to zero on the 26th day of the experiment

  • It should be emphasized that the Cu biosorption process did not follow a linear course and a slight increase in the efficiency of Cu removal from wastewater was observed periodically

Summary

Introduction

The progressive increase in industrialization and human activities translates into an increase in the percentage of waste accumulation worldwide and its release into the environment. A variety of symptoms can appear in organisms, including inhibition of tissue growth and differentiation, organ damage, elevated blood pressure and vascular obstruction, autoimmune diseases, oxidative damage and disruption of DNA methylation, worsening of allergic reactions, as well as sleep and speech disorders, decreased concentration, mood swings, and depression [Qu et al, 2013]. They can modify the production and function of cellular enzymes [Ageena, 2010]. Exposure to heavy metals above safe levels can cause serious health damage
