A system for dissolving solid chemical may include three reservoirs positioned in a vertically stacked arrangement. A solid chemical reservoir configured to receive solid chemical to be dissolved may be nested in a solution generator reservoir into which water is introduced to erode the solid chemical. A dissolved chemical reservoir can be positioned under the solid chemical reservoir and the solution generator reservoir. The dissolved chemical reservoir can store solution generated using the system. In some examples, a recirculation circuit is used to recirculate water introduced into the solution generator reservoir until a solution having a target concentration of the chemical being dissolved is achieved. The recirculation circuit may include a recirculation line having an outlet aimed at the bottom wall of the solid chemical reservoir.

Novel fluorophores and their use as fluorescent tags for polymers used in wastewater treatment. The fluorophores are quaternary amine salts that can be used to synthesize fluorescent tagged polymers that are stable at varying pH, have significant water solubility, and may be fluorescent at wavelengths greater than 550 nm. The fluorophores readily undergo polymerization with vinylic monomers to form fluorescent tagged polymers with excellent incorporation of fluorophore into the polymer framework. The fluorescent tagged polymers are useful to monitor and optionally dose industrial wastewater.
