Intend to build a career as a key player in challenging and creative environment with committed & dedicated people of leading corporation, which will help me to utilize my potential completely for both the organization and my personal growth.
Work Experience:
Worked as a Project Assistant in CSIR-Central Mechanical Engineering Research Institute (CMERI) from 2015-2017. In this tenure, I prepared different low-cost adsorbents for removal of pollutants from groundwater, testing several water quality parameters like pH, TDS, Conductivity, Salinity, Hardness, Alkalinity, BOD, COD, TOC etc. Prepare lab reports and collected samples from different locations in Durgapur. I also performed column study for checking removal (%) of fluoride using various adsorbents by varying different operating parameters like bed height, initial concentration and flow rate.

Enhancing selenium removal using pre-treated natural clay: experimental investigation and predictive modeling Gude Ramesh, Biswajit Ruj, Bhaskar Bishayee, Rishya Prava Chatterjee, Ramesh Kumar, Moonis Ali Khan, Byong-Hun Jeon, Jayato Nayak, Sankha Chakrabortty Environmental Research Communications, 2024 A heat treatment methodology was adopted as a pretreatment strategy, altering the porous structure of the clay to minimize leaching for selenium adsorption in an aqueous system. Rigorous experiments were carried out in batch mode to determine optimal parameters across various variables, including contact time, adsorbent dosages, selenium concentrations, pH, temperature, and stirring speed during selenium removal using natural clay. Investigating several kinetic and isotherm models revealed the best fitting for the pseudo-second-order and the Langmuir isotherm. Endothermic and spontaneous characteristics of the adsorption process were shown during thermodynamic analysis. In this study, a predictive model for the efficiency of selenium separation was established using Response Surface Methodology (RSM). Additionally, an Artificial Neural Network (ANN), a data-driven model, was employed for comparative analysis. The predictive model exhibited a high degree of agreement with experimental data, demonstrated by a low relative error of <0.10, a high regression coefficient of >0.97), and a substantial Willmott-d index of >0.95. Moreover, the efficacy of pre-activated clay in selenium removal was assessed, revealing the superior performance of ANN models over RSM models in forecasting the efficiency of the adsorption process. This research significantly advances an effective and sustainable material for selenium removal, providing valuable insights into predictive modeling techniques applicable to similar contexts to boost scale-up confidence during industrial implementation in affected regions.
Reutilization of ferro-arsenic waste sludge for the development of concrete blocks through solidification: conservation of natural aggregates with policy suggestion Biswajit Ruj, Jayato Nayak, Swarup Ranjan Debbarma, Preetam Kumar Mondal, Bhaskar Bishayee, Rishya Prava Chatterjee, Sankha Chakrabortty Biotechnology and Genetic Engineering Reviews, 2024 In the present study, arsenic sludge and iron sludge extracted from a laboratory scale water treatment plant were aimed to reutilize for the development of concrete blocks. Three different grades (M15, M20 and M25) of concrete blocks were made by blending of arsenic sludge and improved iron sludge (50% sand and 40% iron sludge) in the range of density of 425 to 535 kg/m3 at an optimum ratio of 10:90 (arsenic: iron sludge) followed by mixing of designed quantity cement, coarse aggregates, water and additives. Concrete blocks developed based on this such combination exhibited 26 MPa, 32 MPa and 41 MPa compressive strengths, and 4.68 MPa, 5.92 MPa and 7.78 MPa tensile strengths for M15, M20 and M25, respectively. In comparison with the developed concrete blocks and the blocks made with 10% arsenic sludge and 90% fresh sand, the developed ones (employing 50% sand, 40% iron sludge and 10% arsenic sludge) showed more than 200% higher strength perseverance on average. Successful Toxicity Characteristic Leaching Procedure (TCLP) and compressive strength of the sludge-fixed concrete cubes classified it as a non-hazardous and completely safe to use value-added material. This process involves stabilization of arsenic-rich sludge generated from high-volume long-run laboratory-based arsenic-iron abatement set-up from contaminated water with successful fixation in solid matrix of concrete through complete substitution of natural fine aggregates (river sand) in cement mixture. Techno-economic assessment reveals such concrete block preparation at $0.09 each which is lesser than 1/2 of the present market price of same quality concrete block in India.
Tertiary treatment of coke-oven wastewater using suspended and immobilized whole live cells of constructed bacterial–microalgal consortium: modeling and optimization using ANN–GA hybrid methodology Abhilasha Rai, Bhaskar Bishayee, Annasha Dey, Abhay Kumar, Sandip Kumar Lahiri, Jitamanyu Chakrabarty, Susmita Dutta Water Science and Technology, 2023 Coke-oven wastewater (CW), containing an array of toxic pollutants above permissible limits even after conventional primary and secondary treatment, needs a tertiary (polishing) step to meet the statutory limit. In the present study, a suitable bacterial–microalgal consortium (Culture C) was constructed using bacterial (Culture B: Bacillus sp. NITD 19) and microalgal (Culture A: a consortium of Chlorella sp. and Synechococcus sp.) cultures at different ratios (v/v) and the potential of these cultures for tertiary treatment of CW was assessed. Culture C4 (Culture B:Culture A = 1:4) with inoculum size: 10% (v/v) was selected for the treatment of wastewater since the maximum growth (3.08 ± 0.57 g/L) and maximum chlorophyll content (4.05 ± 0.66 mg/L) were achieved for such culture in PLE-enriched BG-11 medium. During treatment of real secondary treated coke-oven effluent using Culture C4 in a closed photobioreactor, the removal of phenol (80.32 ± 2.76%), ammonium ions (47.85 ± 1.83%), fluoride (65.0 ± 4.12%), and nitrate (39.45 ± 3.42%) was observed after 24 h. In a packed bed bioreactor containing immobilized C4 culture, the maximum removal was obtained at the lowest flow rate (20 mL/h) and highest column bed height (20 cm). Artificial intelligence-based techniques were used for modeling and optimization of the process.
Removal of Fluoride from Synthetic Wastewater Using Carbonised Saw Dust and Suspended and Immobilised Culture of Pseudomonas oleovorans Strain NITD 20-A Comparative Study Bhaskar Bishayee, Abhilasha Rai, Biswajit Ruj, Susmita Dutta Asian Journal of Water Environment and Pollution, 2022 In the present research, three agents such as saw dust (carbonised), waste of the timber industry, suspended bacterial cells of Pseudomonas oleovorans strain NITD 20 and immobilised whole live bacterial cells were used individually for fluoride removal from synthetic wastewater. Carbonised saw dust was used first as an adsorbent at optimum conditions such as pH 7±0.2, initial fluoride concentration of 15 mg·L-1, particle size of 0.10 mm, adsorbent dose of 60 g·L-1, contact time of 10 h and stirring speed of 120 rpm, and it showed 79.04±0.196% fluoride removal. In the present study, both suspended and immobilised cells of ‘Pseudomonas oleovorans strain NITD 20’ were used for the defluoridation process. Immobilisation was done onto the carbonised saw dust. The maximum removal was observed for suspended cells at 94.5±2.1% and immobilised cells at 98±1.23% in 10 h and 8 h incubation periods, respectively, from 15 mg·L-1 fluoride containing synthetic wastewater.
