A Sustainable Greywater Treatment Method
Addressing the ever-demanding crisis of water scarcity, Dr Mohit Aggarwal, Assistant Professor from the Department of Civil Engineering, has published a paper titled “Polyculture Microalgae and Zno/GAC-nanocomposite System for Greywater Treatment” in the Q1 journal Biomass and Bioenergy with an impact factor of 5.8. In his research, Dr Aggarwal explores sustainable methods to treat wastewater with algae and nanoparticles, providing an efficient method to reuse greywater and reduce water consumption.
Abstract
This study explores sustainable greywater treatment using microalgae and a ZnO/GAC nanocomposite in a 15-day batch photobioreactor. The system achieved significant nutrient removal, with 80% TOC, 94.2% PO43−, and 99.6% NH4+ efficiencies. Microalgal growth was enhanced by the nanocomposite, reaching a density of 1.8 g/L. The resulting biomass had a high heating value of 18.32 MJ/kg. The ZnO/GAC nanocomposite maintained effective removal over four cycles. The treated greywater met reuse standards for toilet flushing, with pH 8.5, turbidity <4 NTU, and COD, NH4+, and PO43− of 34, 0.032, and 0.48 mg/L, respectively.
Explanation of the research in layperson’s terms
Water scarcity and pollution are serious problems, and our research aims to find an environmentally friendly way to treat greywater (wastewater from sinks, showers, etc.). We explored the use of algae combined with special nanoparticles (zinc oxide) to clean the water more effectively. The algae grow in the water and help remove harmful substances like carbon, phosphorus, and nitrogen. The nanoparticles make this process even more efficient.
After treatment, the water is clean enough to be reused, for example, in toilet flushing. This method not only helps clean wastewater but also provides a sustainable way to reuse it, which can reduce water consumption and help the environment.
Practical implementation/ Social implications of the research
Practical implementation
The system developed in this research can be implemented in decentralised greywater treatment units, especially in water-scarce areas. It provides a cost-effective, eco-friendly solution for treating household or industrial greywater. The treated water meets the quality standards for reuse in applications like toilet flushing or landscape irrigation, reducing freshwater demand.
Social implications
This research promotes water recycling, contributing to sustainable water management practices and helping to address water scarcity issues. This can improve access to water in communities with limited resources, reduce the pressure on freshwater supplies, and lower the environmental impact of wastewater discharge, leading to healthier ecosystems and communities. Additionally, adopting such systems on a larger scale can foster greater awareness of water conservation and responsible resource usage.

A Novel Breakthrough on Developing Heterogeneous Small-World LPWANs
The Department of Electronics and Communication Engineering is delighted to announce that Assistant Professor Dr Anirban Ghosh, PhD scholars Mr Naga Srinivasarao and Ms Manasa Santhi, and BTech student Mr Sk Abdul Hakeem have filed and published their patent, “A System and a Method for Low Transmission Delay and Energy Efficiency,” with Application No: 202441045389. The research cohort has demonstrated groundbreaking research on integrating Small-World Characteristics (SWC) into Low-Power Wide-Area Networks (LPWANs) through Reinforcement Learning.
Abstract
To support the rapid growth of Internet of Things (IoT) applications, networking technologies like Low-Power Wide-Area Networks (LPWANs) are evolving to provide extended network lifespan and broader coverage for Internet of Things Devices (IoDs). These technologies are highly effective when devices remain stationary under static conditions. However, practical IoT applications, ranging from smart cities to mobile health monitoring systems, involve heterogeneous IoDs that move dynamically, leading to changing network topologies. Typically, dynamic networks use multi-hop data transmission schemes for communication, but this method presents challenges such as increased data latency and energy imbalances. To address these issues, this patent introduces a novel approach that integrates recent advancements in social networks, specifically Small-World Characteristics (SWC), into LPWANs using Reinforcement Learning. Specifically, the SWCs are embedded into heterogeneous LPWANs through the Q-learning technique. The performance of the developed heterogeneous Small-World LPWANs is then evaluated in terms of energy efficiency (including the number of alive and dead IoDs, as well as network residual energy) and data transmission delay within the network.
Explanation of Research in Layperson’s Terms
The existing or the present technology moves around the applications that are either static or dynamic in nature, but the current invention considers a realistic IoT application that contains both static and dynamic nodes in the network. However, maintaining low data transmission delay and high network longevity over such a heterogeneous network is a challenge. By integrating SWCs over the developed heterogeneous networks using Q-learning technique helps in minimizing the data transmission delay and improves the network lifetime (energy efficient data transmission).
Practical Implementation of the Research
Applications that contain both static and dynamic nodes, such as smart health care systems, smart environmental monitoring systems, real-time traffic monitoring systems, and smart cities and homes, require less data transmission delay and high network longevity.
