Abstract: 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.

Abstract: A method for efficiently removal of oxidised selenium from liquid, such as FGD wastewater. The method involves adding a non-iron-based reducing agent (e.g. sodium dithionite) and preferably Fe(II) ions to the liquid at a pH of above 7.5 or 8 and precipitating elemental selenium from the liquid.

Abstract: The present disclosure relates to a formulation and a process for the removal of inorganic impurities from waste water. The formulation consists of a blend of at least one alkali metal aluminate, at least one cationic organic coagulant and optionally at least one alkalinating agent in pre-determined proportions. The process for decontamination using the afore-stated formulation includes steps such as admixing, settling, microfiltration and optionally acidification, ultrafiltration and reverse osmosis. The disclosure further provides an apparatus for the removal of inorganic impurities from waste water.
