摘要:The invention relates to the development of oligomer-type biodegradable saponified polyamide resins in emulsion intended for wastewater treatment. The invention is used mainly for continuous flows owing to the reactivity pattern of the prepolymer and the operation thereof depends on the double-layer theories (Guy Chapman) and the electrochemical and magnetic states of the waste that can be suspended in the water, thereby forming a micellar system which, owing to the electrochemical and chemical potential difference, separates the suspendable solids and thereby provides separated wastewater flows suitable for reuse. The invention is novel in that the resin is a highly reactive cationic-type resin which quickly separates the water flows with the aid of anionic flocculants, the efficiency thereof being due to the reactivity of the micelles formed during synthesis. The invention can be adapted to processes for the treatment of water in containers without generating a drop in efficiency or in the quality of the wastewater produced for reuse, while meeting quality standards.
