Novel pilot scale photocatalytic treatment of textile & dyeing industry wastewater to achieve process water quality and enabling zero liquid discharge
Research Paper
| June 22, 2021
This paper presents a novel end-to-end pilot scale photocatalytic treatment of real textile & dyeing industry effluent, which involved innovative approach in primary treatment, followed by Heterogenous Photocatalysis (HP) involving nano-TiO2/UV as secondary treatment and suitable filtration leading to treated water meeting process water quality enhancing water re-use efficiency. This enables Zero Liquid Discharge (ZLD); which is the need of the hour in tackling problems of po.int source pollution and Water Conservation in developing countries like India.

Nanoscale 2D semi-conductors – Impact of structural properties on light propagation depth and photocatalytic performance
Research Paper
| June 21, 2021
The performance of photocatalytic materials are largely dictated by the crystalline and optical properties of the semi-conductors. The density of photo-generated electron and hole pairs is greatly influenced by the light penetration in photocatalytic material, leading to specific degradation kinetics. In this work, the relationship between the metal oxide film thickness and the overall materials optical and photocatalytic performances are systematically established for the first time.
Surfactant-modified titania for cadmium removal and textile effluent treatment together being environmentally safe for seed germination and growth of Vigna radiata
Research Paper
| June 21, 2021
The present work describes synthesis, detailed characterization, and application of bare and surfactant-modified titania nanomaterials (NMs) for various wastewater treatment applications as individual cases like cadmium (Cd) removal, methylene blue (MB) dye degradation, and treatment of real textile and dyeing industry effluent. These NMs are used as adsorbents and photocatalysts in an indegenously developed end-to-end treatment process and a photocatalytic reactor for treatment of textile wastewater.
Improving energy efficiency and economic feasibility of photocatalytic treatment of synthetic and real textile wastewater using bagasse fly ash modified TiO2
Research Paper
| June 21, 2021
TERI (The Energy and Resources Institute) has recently developed a novel wastewater treatment technology called TERI Advanced Oxidation Technology (TADOX), which provides an end-to-end treatment of textile and dyeing industry wastewater within a few hours without any kind of bioremediation in the treatment trail. It involves UV/n-TiO2 Photocatalysis during secondary treatment; Photocatalysis, is a promising approach for treating difficult wastewater, however there is always effort to reduce cost and electrical energy consumption.
Electro-catalytic membrane reactors for the degradation of organic pollutants – a review
Research Paper
| June 21, 2021
The occurrence and accumulation of persistent organic pollutants (POPs) in wastewater represent global challenges since they are bio-refractory pollutants, which cannot be remediated with classical wastewater treatment systems. Amongst emerging technologies, POPs may be treated by electrochemical advanced oxidation processes to remediate selective contaminants through specific degradation pathways.

आप अपनी संतानों से प्रेम करते हैं न, तो ये ईंट पत्थर के बंगले काम न आएंगे जिसे आप जोड़ रहे …काम आएगी शुद्ध हवा, साफ पानी, हरे जंगल, चहकते पक्षी…खेलते हिरण…झपटते शेर…यानी सम्पूर्ण जैवविविधता…!!!
Exploring Endophytes Using “Omics”: An Approach for Sustainable Production of Bioactive Metabolites.
Research Paper
| June 15, 2021
Bioactive secondary metabolites from endophytic fungi provide a robust foundation for novel natural metabolic scaffolds with a plethora of applications. These filamentous fungi contain gene clusters that encode highly significant metabolites; however, many of these clusters remain concealed in laboratory-like settings. Consequently, disparate strategies encompassing genetic manipulation(s) and or metabolomic interventions are obligatory for activating such silent gene clusters and improving metabolite yield.
Linkages between Gender, Entrepreneurship, and Access to Energy - What Factors Explain Women Empowerment?
Research Paper
| June 15, 2021
The gender-energy-entrepreneurship nexus involves the challenges of engendering the energy value chain and the multifaceted challenges of empowering women through energy. It is widely acknowledged that access to a range of modern energy services would provide women the opportunity to operate and expand their enterprises, increase the stability of the business and customise their products to the demands of the market. These may also help to create a potential pathway for women’s empowerment through a shift in power relations that perpetuate inequalities.
Altered River Flows and Nature's Fury: Need for Efficient Water Resources Management
Article
| June 14, 2021
The theme of this year's World Environment Day is Ecosystem Restoration. Ecosystem restoration can take many forms, such as growing trees, greening cities, rewilding gardens, changing diets or cleaning up rivers and coasts.
