Abstract
Described is a method to recycle laden fluid containing explosives or neutralized chemical agents. For example, the explosive laden fluid is passed through four filtering stages; a clarifier, a filter press, a sand filter and, ultimately, a reverse osmosis device. The feed water to the reverse osmosis device is a saturated solution of explosive or neutralizing chemical agent. The resulting permeate is about 10 ppm of explosive or neutralizing chemical agent.
