Abstract
Methods and systems for chemical management. In one embodiment, a blender is coupled to a processing system and configured to supply an appropriate solution or solutions to the system. Solutions provided by the blender are then reclaimed from the system and subsequently reintroduced for reuse. The blender may be operated to control the concentrations of various constituents in the solution prior to the solution being reintroduced to the system for reuse. Some chemicals introduced to the system may be temperature controlled. A back end vacuum pump subsystem separates gases from liquids as part of a waste management system.
