Abstract

Phenolic industrial wastewaters and their release into the environment are environmental problems. Among the various methods for separating phenol from wastewater, the adsorption process is a widely used method. The aim of this study is economic evaluation of industrial production of nano biocarbon adsorbent prepared from peanut shell. The unique capability of this adsorbent, having three features simultaneously, ultra-fast and complete removal of phenol, and high adsorption capacity, has made it a practical and competitive product. Based on the economic evaluation, the production of this adsorbent using the method presented in this study is economically profitable and costs 1440 thousand rials per kilogram of final product. The payback period for different discount rates is 3.3 to 5.9 years. The internal rate of return is 40% for ten years from the time of implementation of the production plant, which is higher than the common bank discount rate (23%) and indicates the profitability of the project.
