Process for producing an inorganic polymer flocculant containing aluminum chloride as a main component

摘要

0.2-1% of at least one iron salt in ferrous chloride, ferric chloride, ferrous sulfate, ferric sulfate, polychloride iron and polyphosphoric acid iron is added to aluminum chloride obtained by direct reaction between metallic aluminum and hydrochloric acid It is an object of the present invention to provide a flocculant having excellent flocculation effect and wide applicability to various kinds of water treatment, economical efficiency and work efficiency by producing a basic aluminum chloride flocculant of iron coexistence system by expanding the PH area to the acidic side to widen the flocculation width.
