	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.

	Here we present, the design and optimization of a 100 kV DC thermionic electron gun, and a transport channel that provides transverse focusing through a normal conducting solenoid and longitudinal bunching with the help of a single gap buncher for a 1.3 GHz, 40 kW, 1 MeV superconducting electron accelerator. The accelerator is proposed to treat various contaminants present in potable water resources. A 100 kV thermionic electron gun with LaB6 as its cathode material was intended to extract a maximum beam current of 500 mA. To minimize beam emittance, gun geometry i.e. cathode radius, and height and radius of the focusing electrode are optimized. The minimal obtained emittance at the gun exit is 0.3 mm.mrad. A normal conducting focusing solenoid with an iron encasing is designed and optimized to match and transport the beam from gun exit to the superconducting cavity. Finally, a 1.3 GHz ELBE type buncher is designed and optimized to bunch the electron beam for further acceleration.
