Abstract

A de-watering system for liquid industrial waste from an industrial cleaning process is provided. The liquid industrial waste has an initial water content, and comprises detergents and solid waste. A de-watering bed (430) holds the liquid industrial waste. Air in a first zone (420) is enclosed by a transparent structure (410) and is heated by the sun during daytime. A first controllable opening (450) controls a rate of flow of air in the first zone (420). Water from the liquid industrial waste evaporates into heated air in the first zone (420). An air removal conduit (440) allows heated air to vent to the atmosphere. A control system (380) selectively opens the first controllable opening (450), to regulate the flow of air. De-watering continues until a selectable end point, based on residual water content of the waste, or a final concentration of non-water components.
