A transportable water purification unit with a reverse water purification unit (ROWPU) (20), particularly for military use, is arranged to process municipal and other chlorinated water without damage to the reverse osmosis filtration elements. A modular transportable dechlorination device (22) is coupled between the inlet of the ROWPU and a source of chlorinated water, such as municipal fire hydrant, swimming pool, etc. The dechlorination device has a number of tubes (36) mounted on a frame (38), at least some containing integral reticulated metallic dechlorination elements, the tubes being interconnected by quick connect removable U-fittings at their ends, whereby access is obtained to the reticulated elements (44), which can be in cartridges, and the order of the tubes along the flowpath can be altered. The reticulated dechlorination elements preferably comprise a Cu-Zn (brass) alloy and have a surface area to volume ratio of 1500 to 500, preferably 300 to 350. The device allows a tactical-type water treatment installation to couple to any source notwithstanding chlorination, to purify water that may have been contaminated or even poisoned by chemical or biological agents. |
