Solid chemical dissolution system with small footprint and limited offgassing

A system for dissolving solid chemical comprising:

• (a) a solid chemical reservoir configured to receive a solid chemical to be dissolved, the solid chemical reservoir having:
• (i) a product support surface having a plurality of apertures configured to allow diluent to flow therethrough;
• (ii) at least one sidewall extending vertically upwardly from the product support surface;
• and
• (iii) a liquid outlet opening extending through the at least one sidewall that is offset from the product support surface;
• (b) a solution reservoir positioned vertically below the solid chemical reservoir with the liquid outlet opening of the solid chemical reservoir being in fluid communication with the solution reservoir;
• (c) a liquid blocking wall positioned between the product support surface of the solid chemical reservoir and an interior of the solution reservoir to define a liquid filling space between the liquid blocking wall and the product support surface of the solid chemical reservoir;
• and
• (d) a recirculation circuit that includes (i) a recirculation pump and (ii) a recirculation line having an outlet in the liquid filling space between the liquid blocking wall and the product support surface of the solid chemical reservoir, the recirculation circuit being configured to draw liquid from the solution reservoir and discharge the liquid through the outlet of the recirculation line into the liquid filling space, thereby causing the liquid to flow through the plurality of apertures of the product support surface to contact the solid chemical thereon before discharging through the liquid outlet opening back into the solution reservoir.
