ENPAR Technologies uses state-of-the-art electrochemical technology, known as capacitive deionization, to effectively reduce the concentration of total dissolved solids in water. These include arsenic, nitrate, fluoride, sulfates, metals and other ionic compounds. The advantages of this system are its high removal efficiencies, high water recovery, low maintenance and energy costs. A novel application of this technology is to utilize the reject stream to detect chemical and biological pollutants present in low, but biologically significant, concentrations in water. This could improve the detection of diverse contaminants over current methods. This new University of Guelph/ENPAR collaboration aims to determine if the ENPAR ESD technology can remove two surrogate contaminants, the pesticide 2,4 D and the bacteriophage MS2 from different water sources representing chemical and biological contaminants, respectively. The development of a generalized method to concentrate chemical and biological contaminants from water would have industrial and regulatory importance. Successful implementation of the systems will contribute to Ontario's reputation as a leader in water treatment technologies and improve on Canada's position as an exporter of clean technologies.

ENPAR技术采用最先进的电化学技术，称为电容去离子，以有效地降低水中总溶解固体的浓度。这些包括砷、硝酸盐、氟化物、硫酸盐、金属和其他离子化合物。该系统的优点是其高去除效率，高水回收率，低维护和能源成本。该技术的一个新应用是利用废弃物流来检测水中低浓度但具有生物学意义的化学和生物污染物。这可以改善目前方法对不同污染物的检测。这项新的圭尔夫大学/ENPAR合作旨在确定ENPAR ESD技术是否可以从不同的水源中去除两种替代污染物，即农药2，4 D和噬菌体MS 2，分别代表化学和生物污染物。开发一种从水中浓缩化学和生物污染物的通用方法将具有工业和监管重要性。该系统的成功实施将有助于提高安大略作为水处理技术领导者的声誉，并提高加拿大作为清洁技术出口国的地位。
