N1 - Funding Information:
The committed support of the National Science Foundation through grants (PHY-0077423) has made the development of this purification system possible. The I.N.F.N. also provided support to complete the installation in the underground laboratory at Gran Sasso. We also thank G.P. Bellini, G. Ranucci, and M. Pallavicini for their support and oversight at LNGS. The Borexino Steering Committee were vital in organizing and scheduling the successful filling and operation of the Borexino detector. We also wish to thank George Schlowsky, Tom Shaeffer, Stan Lam, and Jim DeNoble of Koch Modular Process Systems for their assistance with the design and construction of the purification system, as well as their guidance in refining operational parameters during start-up. Domenico Barone, Roberto Tartaglia, and Matthias Laubenstein provided invaluable guidance and assistance with the implementation of the safety systems. Ted Lewis and Lazlo Varga helped with much of the specialized machining necessary for the system. Stefano Nisi and Luca Ioannucci provided assistance with laboratory tests at LNGS.

N2 - Purification of the 278 tons of liquid scintillator and 889 tons of buffer shielding for the Borexino solar neutrino detector is performed with a system that combines distillation, water extraction, gas stripping, and filtration. This paper describes the principles of operation, design, and construction of that purification system, and reviews the requirements and methods to achieve system cleanliness and leak-tightness.
