Simulation and sensitivity analysis of spiral wound reverse osmosis process for the removal of dimethylphenol from wastewater using 2-D dynamic model

Abstract

Reverse Osmosis (RO) processes are readily used for removing pollutants, such as dimethylphenol from wastewater. A number of operating parameters must be controlled within the process constraints to achieve an efficient removal of such pollutants. Understanding the process dynamics is absolutely essential and is a pre-step for designing any effective controllers for any process. In this work, a detailed distributed two-dimensional dynamic (x and y dimensions and time) model for a spiral-wound RO process is developed extending the 2-D steady state model of the authors published earlier. The model is used to capture the dynamics of the RO process for the removal of dimethylphenol from wastewater. The performance of the 2-D model is compared with that obtained using 1-D dynamic model before the model is being used to investigate the performance of the RO process for a range of operating conditions.

“…However, applications were initially limited because of intrinsic economic risks associated with the oil production activity and operation constraints related to membrane separations. Nevertheless, the scenario has been changing due to advantages related to the lower energy consumption, low capital investment, low operating costs, and more compact nature of these pieces of equipment [5][6][7].…”

Performance evaluation of multi-stage reverse osmosis process with permeate and retentate recycling strategy for the removal of chlorophenol from wastewater

“…This in turn has encouraged the employment of different abatement technologies to remove phenol from wastewater such as, steam distillation processes, organic solvent extraction, adsorption, oxidation, and membrane technology to achieve this restriction (Pinto et al, 2005;Busca et al, 2008;Mohammed et al, 2016). Among these technologies, the Reverse Osmosis RO has been recognised as an effective process in wastewater treatment applications regarding the removal of organic compounds from wastewater (Al-Obaidi et al, 2018). Also, the pilot-scale studies using single RO membrane module by Srinivasan et al (2010Srinivasan et al ( , 2011; Sundaramoorthy et al(2011a) have confirmed the feasibility of the RO process for the removal of phenol and phenolic derivatives from wastewater.…”
