Equilibrium and Kinetic Modeling on Biosorption of Reactive Red 2 Using Tamarindus indica Fruit Hulls

Chemical Product and Process Modeling (2008)

S. Renganathan Muthulingam Seenuvasan S. Selvaraj Pavan Kumar Gautam M. Velan

Biosorption of Reactive Red 2 dye, from an aqueous solution was evaluated using Tamarindus indica fruit hulls in a batch system. The influence of pH (1-6), temperature (20-30°C) and initial dye concentration (20 to 120 mg/L) on the biosorption process was studied. Maximum biosorption was observed at initial pH of 2.0, temperature of 30°C and at the initial dye concentration of 120 mg/L. Equilibrium data were analysed for Langmuir, Freundlich and generalized isotherm model. The equilibrium data were found to fit very well with Freundlich isotherm model when compared to all other isotherm models studied in the present investigation. Batch biosorption kinetics was studied with different initial dye concentrations and rate of biosorption was determined using pseudo first and pseudo second order rate equations. From the result it was observed that pseudo second order rate expression fit the experimental data well for Reactive Red 2 when compared to a pseudo first order kinetic model.

Design and development of a pilot plant for the treatment of pharmaceutical wastewater containing molasses

Water Practice & Technology (2024)

Suresh Raju Penmetsa Bharat Kumar Allam Deepak Pise Pavan Kumar Gautam Sushmita Banerjee

Abstract The present work deals with the anaerobic treatment of molasses-bearing pharmaceutical wastewater using a specifically designed downflow anaerobic bioreactor (DFAB). The capacity of the designed DFAB was 1,000 L of adequate volume with necessary operational controls. Two types of anaerobic treatment, i.e. mesophilic and thermophilic treatments, were applied to the anaerobic biotransformation of wastewater under investigation. The efficiency of both treatments was compared in terms of reducing biochemical oxygen demand (BOD) and chemical oxygen demand (COD) load, as well as methane production. The anaerobic digestion process was carried out with the help of bacterial strains. The bacterial strains used in the mesophilic operation were acclimatised and utilised for the thermophilic treatment, which is a cost-effective and sustainable approach. A significant reduction in BOD and COD content of the wastewater was noticed after 10 days of retention time. Nearly 72–83% and 80–90% reduction in BOD values were recorded under mesophilic and thermophilic operations, respectively. Approximately 73–86% and 82–93% of COD content were reduced by mesophilic and thermophilic treatment, correspondingly. Methane production of 67 and 74% was achieved under mesophilic and thermophilic treatment, respectively. The designed DFAB showed remarkable treatment efficiency for wastewater and methane production.

Bio‐inspired Nanocomposites for Remediation of Pharmaceutical Pollutants

Pavan Kumar Gautam Saurabh Shivalkar Anirudh Singh M. Shivapriya Pingali Shrutika Chaudhary

Pharmaceutical pollutants cover a wide range of chemicals, including drugs, antibiotics, and hormones, and cause serious harm to humans and aquatic organisms even in low amounts. Therefore, treatment and removal of pharmaceutical contaminants from the wastewater is an utmost concern due to the damaging effects associated with them. Currently, the application of biologically prepared nanosized catalysts for the degradation of pharmaceutical pollutants has emerged as a promising technique due to its remarkable efficiency, low cost, and sustainability. In the present chapter, the use of different kinds of bio-inspired nanomaterials for the degradation of various micropollutants has been discussed. In addition, the factors influencing the synthesis of bioengineered nanoparticles have also been explained.
