Industrial Water recycling refers to a planned reuse of the waste water from an industrial outlet. The treatment of waste water involves several processes and has to meet the required standard of purification. Of course the the reuse of the water will determine the level of purification treatment needed on the industrial waste water. If the water is to be used for drinking purposes, there will be several layers of purification treatment involved, against its use in agricultural farming. This is done by some of the leading companies who have presence in Baltimore.
