Fate of the persistent organic pollutant (POP) Hexachlorocycloheane (HCH) and reemediation challenges(International Biodeterioration & Biodegradation)
(Vartika Srivastava, Tanmay Srivastava, M. Sursh Kumar,140,,43-56,Year : 2019)
|
Persistent Organic Pollutants (POPs) are hazards to human health and exhibit harmful effects to the environment, owing to their typically lipophilic and bio-accumulative nature. Chlorinated compounds are most relevant within the classical POPs, which are both toxic and hazardous. Lindane, ‘γ’ isomer of hexachlorocyclohexane (γ-HCH), is one such organochlorine compound primarily used as a fumigant and an insecticide in agriculture. Due to its continuous use in the past decade throughout the world and severe environmental impacts in terms of toxicity and threats, there is an urgent need to develop cleaning up and remediation strategies for the lindane-contaminated sites. Being electron deficient due to its highly chlorinated nature, the degradation pathway of γ-HCH is previously thought to be generally under anaerobic condition via reductive dechlorination. But both aerobic and anaerobic degradation pathways are suggested for HCH isomers and biodegradation pathway of lindane has been completely elucidated in Sphingomonas paucimobilis UT26. Many bioremediation technologies viz. biostimulation, bioaugmentation, bioreactor systems have been employed so far for the treatment of HCH contaminated soil. However, the potential of these strategies has been tested at the laboratory scale and should be implemented for field-scale treatment of soil and aquatic systems contaminated with lindane and other HCH isomers. This review focuses on the fundamentals about the biodegradation and also various technologies utilized for full-scale remediation of HCH contamination in sediment and soils.

Environmental Applications of Boron-Doped Diamond Electrodes: 1. Applications in Water and Wastewater Treatment
(P. V. Nidheesh, G. DivyapriyaNihal, OturanClement Trellu,Mehmet A. Oturan,,,,Year : 2019)
|
Over the past few decades, environmental applications of the boron-doped diamond (BDD) electrode are reported to be vast and versatile. Applications of BDD electrodes in the field of electrochemical advanced oxidation prodesses (EAOPs) for the abatement of toxic persistent organic pollutants are significant owing to the easy and effective way of treatment This article focuses on highlighting and summarizing the applications of the BDD electrode for the treatment of different synthetic and real wastewaters , such as those involved in pharmaceuticals and personal care products, pesticides/herbicides, dyes, etc. We also review the processes and methodologies involving the synthesis of BDD electrodes and summarize the desirable characteristic features required for the application of EAOPs.

An overview of environmental sustainability in cement and steel production(Journal of Cleaner Production
)
(P.V. Nidheesh, M. Suresh Kumar,231,, 856-871,Year : 2019)
|
Eco-friendly industrial production is essential to save our environment. The present article reviews the sustainability aspects for steel and cement industries, as both are highly demanding. Carbon dioxide emissions from the steel industry can be reduced effectively by carbon sequestration methods. The generation of by-products from steel can be used as raw materials in manufacturing of paints, cement fertilizers etc. The major challenge in cement production is higher input of raw material and fuel in clinker production. These problems can be rectified by adopting suitable co-processing method. Energy requirement can be reduced by using blended cement with highly efficient clinker cooler, dryer, separators, calciner, pre-calciner and waste heat recovery system.

Photoelectro-peroxone process for the degradation of reactive azo dye in aqueous solution(Separation Science and Technology )
(Alphonsa C. Joy, R. Gandhimathi, S.V. Niveditha, S. T. Ramesh, P. V. Nidheesh,,,,Year : )
|
This study evaluated the degradation of reactive yellow F3R (RY F3R) dye by photoelectro-peroxone (PEP) process. The study showed that the PEP gave 97.66% colour and 84.64% TOC removals at 1.176 h−1 which were 14 and 1.4 times greater than photolysis and electro-peroxone processes, respectively. Quenching experiment showed that hydroxyl radical and singlet oxygen were predominant oxidizing species in RY F3R degradation. In addition, results of the colour and TOC removal by the application of PEP to real field textile wastewater showed that PEP offer an efficient and propitious technology for organic pollutant degradation

Continuous treatability of oily wastewater from locomotive wash facilities by electrocoagulation(Separation Science and Technology )
(T. Sravanth, S.T. Ramesh, R. Gandhimathi, P. V. Nidheesh,,,,Year : 2018)
|
The present work focuses on the feasibility of electrocoagulation (EC) process for the treatment of oil and grease wastewater generated from locomotive wash facilities. Experimental investigations have shown the influence of various factors affecting EC using continuous reactor. The effect of various operating parameters, like reaction time, electrode spacing, and applied voltage, was investigated and optimized using Box-Behnken design method. The optimized value of applied voltage and electrode spacing were found to be 28 V and 3 cm, and Chemical Oxygen Demand removal efficiency obtained was 91.9%. As a result, EC process can be an alternative method for the treatment of oily wastewater.

Optimization of batch electrocoagulation process using Box-Behnken experimental design for the treatment of crude vegetable oil refinery wastewater(Journal of Dispersion Science and Technology)
(Preethi Vijayaraghavan, S. T. Ramesh, R. Gandhimathi, P. V. Nidheesh,,,,Year : 2018)
|
The performance of the batch electrocoagulation process for the treatment of real crude vegetable oil refinery wastewater with high COD using sacrificial aluminum anode was explored in this research. Effects of operating factors such as electrolysis time (0–60 min), applied voltage (10–20 V) and electrode spacing (2–4 cm) on the COD removal were investigated. Mathematical model relating these key operating factors and the COD removal was developed using Box-Behnken design. 3-D response surface plots showed that the COD removal significantly increased with increase in electrolysis time and applied voltage till the optimum value. COD removal decreased, when very short or excessive electrode spacing was fixed. Experimental COD removal of 70.8% was attained at the optimized conditions and observed to be in reasonable agreement with the prediction by the Box-Behnken design.

Adsorption of an emerging contaminant (primidone) onto activated carbon: kinetic, equilibrium, thermodynamic, and optimization studies( Environment Monitoring and Assessment)
(,,,,Year : 2019)
|
The current study addresses the removal of an emerging environmental contaminant (primidone) in batch adsorption experiments using commercial-grade powdered activated charcoal (PAC). The experiments for the removal of primidone were performed to identify the effect of various adsorption parameters. The second-order rate expression best represented the adsorption kinetics data. The Freundlich isotherm equation was best fitted to the experimental adsorption data at equilibrium for removal of primidone using PAC. The values for change in entropy (ΔSo) were positive, which indicates that the degree of freedom of the process increases. The negative values of change in enthalpy (ΔHo) and change in Gibb’s free energy (ΔGo) indicate that the physical adsorption is a dominant phenomenon, and the process is feasible and spontaneous. The negative value of ΔHo also represented the exothermicity of the adsorption process. The Taguchi optimization technique calculated the influence of variation of different process parameters, viz., initial pH (pH0), PAC dosage (m), initial adsorbate concentration (C0), solution temperature (T), and process contact time (t), on the removal of primidone by adsorption from aqueous solution. Each of the above parameters was examined at three levels to study their effects on the adsorptive uptake of primidone using PAC (qe, mg g−1), and the optimum value necessary to maximize qe was determined. The findings from the ANOVA indicate that the PAC dose (m) is the most notable parameter contributing 62.16% to qe and a 71.96% to the signal to noise (S/N) ratio data, respectively. The confirmation experiments performed at the optimum parameter condition validated the applicability of the Taguchi design of experiments. The percent removal and adsorptive uptake at the optimal condition were 86.11% and 0.258 mg g−1, respectively.
