The invention is a solvent for powdered chemicals in a liquid process stream. This controlled dissolution occurs within a reactor by manipulating the level of the process liquid. This leveling is achieved by leveraging the opposing pressures of the discharge from a process circulation pump and the gas pressure, controlled by an automated pneumatic unit. The invention overcomes the drawbacks of prior art by offering, unlike solutions based on motorized dosing syringes or energy-intensive venturi systems, a purely fluidic, non-clogging solution without rotary or linear seals for dissolving powdered products in industrial chemical process liquids, as well as in public or private swimming pools of all sizes. This solvent is applicable to numerous industrial processes, particularly for chlorinating swimming pool water or any other liquid that reacts with a solid product.
