The need for industry to reduce the discharge of aqueous effluents at source, recycle the water associated with those effluents, and recover valuable product intermediates from them for process recycle becomes increasingly important, under mounting external pressures.The presets project aims to develop a novel and highly promising surfactant-based technique for the removal and concentration of aqueous pollutants and valuable components, including phenoxyacids (such as pesticides) and other organic acids, and heavy metal ions. It is based on a colloidal fkxxulation process known as AMF. In the process, pollutants associate selectively with surfactant micelles by ionic binding. The micelles are then made to flocculate through the addition of a strong multivalent electrolyte, which neutralises the micellar charge. The flocculate can then be separated by normal filtration; the pollutant is recovered by solvent extraction, and fkxxulaM and surfactant recycled to the AMF process.A current feasibility study on AMF at Nottingham has already demonstrated a 'proof of concept. This work will be extended by fully developing AMF as an economic, continuously operated water treatment process, with the ability to recycle selectively useful components from the effluent strum. As part of the study, a pilot plant will be constructed and operated in order to evaluate and optimise the efficiency of the removal and recycle process.
