Abstract

In a method for treating a contaminated fluid stream, a characteristic of a flow of the composition to a carbon adsorption zone is sensed. The sensing is remotely monitored to determine a treatment for the contaminated fluid stream. The contaminated fluid stream is then treated according to the monitoring. A system for treating a contaminated fluid stream comprises a sensor that senses a characteristic of a flow of a contaminated fluid stream prior to treatment and a monitor to receive information concerning the characteristic from the sensor and to consequently control the carbon adsorption zone to treat the contaminated fluid stream. The monitor is situated at a location remote from the carbon adsorption zone.
