ABSTRACT:
A portable system for on-site monitoring and treatment of water comprising a protective enclosure adapted to be positioned proximate a site of collected water, an internal fluid flow system disposed within the enclosure comprising a first conduit extending from a dirty water inlet on the enclosure to a pair of dirty water outlets and a second conduit extending from a return water inlet on the enclosure to a filtered water outlet and a clean water outlet. Probes are provided in the conduits for monitoring fluid parameters therein and communicating those parameters to a controller within the enclosure. The controller compares the measured parameter levels with predetermined acceptable levels and actuates valve members in said conduits in response to the measured parameter levels to selectively communicate the respective conduits with respective outlets for the treatment of water passing through the system.
