Abstract: A mobile surface contaminant extracting and water recycling apparatus comprises a standard truck, pickup, trailer or other wheeled container that is modified by the addition of a clay-based flocculent powder wastewater treatment unit. Mounted in combination with the wheeled container and the wastewater treatment unit is a vacuum steam cleaning unit. Steam is sent from the cleaning unit and sprayed by pressure guns onto the contaminated surface of a parking lot or other surface to be cleaned. The surface contaminants become emulsified in water condensed from the steam, which contaminated water then is vacuumed up by cleaning wands and returned by hose to the steam cleaning unit on the truck bed. From the steam unit, the contaminated water is piped to the adjacent truck-mounted wastewater treatment unit. The water is churned in the latter unit in the presence clay-based powder. The resultant floc sludge is deposited on top of porous cloth on a draining tray or trays.
