摘要
The present invention discloses a process for producing aluminum polysulfate silicate using aluminum oxide and a silicon dioxide scavenging catalyst. More specifically, the present invention relates to a process for producing a polyphosphoric acid, which is capable of producing at a cost lower than the production cost of a currently used commercial coagulant by using aluminum oxide and a silicon dioxide spent catalyst, satisfying the criteria of a water treatment agent notified by the Ministry of Environment, A process for producing aluminum silicate is disclosed.;
