Syntheses, chemical effluents, control

The soluble Si and Al, present in the final effluent after the TSA, as completed by following the procedures described in Chap. 5 [3], can be altered if pure SiOa and/or AI2O3, in different proportions, are added in the effluent externally. A controlled chemical reaction, in the chemically modified effluent, might be helpfiil to yield improved zeolites, which in turn would facilitate synthesis of comparatively different grades of zeolites as compared to those obtained from the TSA. This endeavor is also expected to have a zero effluent, as an additional advantage of the fly ash zeolite synthesis process.
