IIPE developed eco-friendly muddy water treatment solutions

The Indian Institute of Petroleum & Energy (IIPE), Visakhapatnam, has made a significant breakthrough in water treatment technology through its collaborative research efforts with other esteemed institutions. The innovative 'Surface Modification Technique of Membrane' promises to address the challenges associated with water treatment, particularly for muddy river water, in an eco-friendly and cost-effective manner.

Addressing the Challenges of Water Pollution

Water pollution has emerged as a major issue in both rural and urban areas, with the quality of water being adversely affected by contamination from various sources. Sludge, riverbed sediments, waste residues, and other pollutants can severely degrade water bodies, leading to habitat degradation, species displacement, and the spread of waterborne diseases.

Muddy water, in particular, poses significant challenges. It reduces oxygen levels, blocks sunlight from penetrating the water, and carries a host of pollutants, contributing to the degradation of aquatic ecosystems. Effective and sustainable water treatment solutions are crucial for mitigating these issues and ensuring access to clean and safe water for various purposes.

Collaborative Research Efforts and Innovative Findings

The IIPE, in collaboration with researchers from Assam Science and Technology University in Guwahati, Gauhati University, Pragjyotish College, and the Institute of Advanced Study in Science and Technology, has undertaken extensive research to address the challenges associated with water treatment. Their findings have been published in the prestigious "Nature Scientific Reports" journal, under the title "Role of Plasma Process Gas on Permeate Flux Augmentation of Cellulose Nitrate Membrane for Mud Water Treatment."

The study focuses on the use of plasma process gas to improve the permeate flux (the rate at which water passes through a membrane) of cellulose nitrate membranes, thereby enhancing their effectiveness in treating muddy water. This innovative approach has the potential to revolutionize water treatment processes across various industries and applications.

The Surface Modification Technique of Membrane

Membranes are widely used for the filtration of contaminated water in various industries. However, one of the main concerns with membrane filtration is the lifespan and the frequency with which they need to be replaced. Membrane replacement can be a significant cost factor and can affect the efficiency of the filtration process.

The 'Surface Modification Technique of Membrane' developed by the IIPE and its collaborators aims to address these challenges by extending the lifespan of membranes and enhancing their performance. This technique involves modifying the surface properties of membranes through various methods, such as graft polymerization, plasma treatment, layer-by-layer assembly, chemical vapor deposition, UV irradiation, membrane annealing, atomic layer deposition, and covalent bonding.

By altering the surface characteristics of membranes, researchers can improve their hydrophilicity, permeability, selectivity, and overall efficiency in filtration processes. This not only reduces the need for frequent membrane replacement but also enhances the cost-effectiveness of water treatment operations across various industries.

Environmental Benefits and Industrial Applications

One of the key advantages of the 'Surface Modification Technique of Membrane' is its eco-friendly nature. Unlike traditional methods that often rely on harsh chemicals or solvents, this technique utilizes non-toxic gases in the surface modification process, minimizing environmental impact and aligning with sustainable practices.

According to Dipankar Pal, Assistant Professor of Chemical Engineering at IIPE, this innovative technology has potential applications in various water-intensive industries, including pharmaceuticals, food processing, textiles, and biotechnology. Additionally, it can play a crucial role in environmental monitoring and protection by reducing the detrimental effects of pollutants on water bodies.

The research initiative has received funding through an Institute Research Grant provided by IIPE, underscoring the institute's commitment to promoting innovative solutions and addressing pressing environmental and industrial challenges.

As the demand for clean and safe water continues to rise, the 'Surface Modification Technique of Membrane' developed by the IIPE and its collaborators represents a promising solution for sustainable and cost-effective water treatment. By addressing the limitations of conventional membrane filtration processes and offering an eco-friendly alternative, this innovative technique has the potential to make a significant impact on water management practices across various sectors.
