1. An apparatus for regenerating a caustic solution, comprising:
a transportable container module having a floor and walls, the container module configured to contain liquid chemicals without leaking outside the module; the container module containing a regeneration system, the regeneration system configured to remove aluminum and to increase the concentration of sodium hydroxide in a caustic solution, the regeneration system comprising: a mixing tank inside the container module, the mixing tank configured to receive caustic solution from a cleaning tank outside the container module, the mixing tank further configured to receive water that is added to the caustic solution to optimize the concentration of total caustic; a crystallizer tank inside the container module, the crystallizer tank configured to receive the caustic solution from the mixing tank, the crystallizer tank containing a concentration by volume of alumina trihydrate crystals that mix with the caustic solution to form a crystallizer solution; a plurality of air mixing wands, the air mixing wands configured to mix the crystallizer solution by air agitation to create a chemical reaction that regenerates sodium hydroxide and precipitates alumina trihydrate crystals, wherein after said chemical reaction, the crystallizer solution comprises a supernatant of a regenerated caustic solution and a plurality of said alumina trihydrate crystals. |
