Abstract

Poly-ferric magnesium sulfate coagulant as another water purifying agent besides poly-aluminum multi-salt can be quantitatively produced through ferrous sulfate oxidation with high product concentration. This article starts with the selection of raw material, then elaborates process flow from a small-scale lab simulate experiment to a large-scale production of this high concentration water purifying agent. According to the corporate technical standard of this product, chemical compositions of the primary material (ferrous sulfate heptahydrate) and auxiliary materials (alkalizing agent, oxidizer, etc.), and the alkalinity of the product (B=8%), this article provides calculation of the raw materials’ input and output for producing 1 ton of the product liquid. The reaction is carried out step-by-step in a heating reactor equipped with acidic mist re-flux tower and filtration devices. The first step: ferrous sulfate oxidation by sodium chlorate; the second step: polymerization, precipitation, and filtration separation; the third step: arsenic and heavy metal check and precipitate separation by flocculating precipitant and metal chelating precipitant; last, use the laboratory test results to back calculating alkalinity (B%), coagulation strength (C%), and molecular formula of the final product liquid. This article not only rationalizes the feasibility with chemical/physical mechanisms this technique, formulation, production method, but also guides through the back calculation to provide data of the properties as a documentation of the certificate of analysis for the product.
