	Here, we report our first step towards tackling this issue at the roots by irradiating the pharmaceutical effluents from a stages of their existing treatment plant with an Electron Beam (EB) with doses varying from 25 kGy to 200 kGy. We have used a normal conducting pulsed wave linear accelerator developed by SAMEER. It produced a pencil beam of electrons of energy 6 MeV with an average current of 16 micro-Ampere. To ensure optimum dose delivery, Fluka-Flair Simulations have been used. We have successfully demonstrated that electron beam irradiation along with the use of conventional techniques like coagulation after the irradiation can further increase the efficacy of the process with a final reduction in Chemical Oxygen Demand (COD) to be as large as 65% in some of the cases.

	To treat industrial effluents including contaminants of emerging concern (CECs), Irradiation treatment by electron beam accelerator has shown promising results. Our aim is to design and develop a superconducting linear electron accelerator. A 1.3 GHz, three cell conduction cooled, TM class superconducting cavity has been proposed to accelerate a 100 mA electron beam from 100 keV to 4.5 MeV. The main aim of the design is to optimize the cavity for low heat loss and high accelerating gradient. The optimized ratio of peak surface electric and magnetic field to accelerating field for cavity are Epk/E_acc= 2.72 and Hpk/E_acc= 4.11 mT/(MV/m). The optimized Geometry factor (G) and R/Q values for this cavity are 246.7 and 306.4 ohms respectively. Here we also addressed other multiphysics issues such as Lorentz force detuning (LFD), Higher order modes (HOMs) and Multipacting. The multiphysics analysis helps to estimate the degree of these challenges. The final Lorentz detuning factor of the cavity has been reduced to 0.12 Hz/(MV/m)2, HOMs of 2.18 and 2.9 GHz modes are dominating except the main mode and Multipacting phenomena is not found at 15 MV/m of accelerating gradient.
