Conclusions

Results of a study of the process of cleaning up zinc-containing wastewater on a pilot unit in the Mogilev “Khimvolokno” Industrial Association artificial fibre plant have shown the possibility of removing zinc ion from wastewater with phosphoric acid solutions. Basic parameters of the precipitation and clarification stages have been determined.

It has been found that the precipitate formed in the wastewater clean-up process can be used to enrich phosphate fertilizers with zinc.

The proposed technology for cleaning up wastewater will make it possible to solve the problem of utilizing the zinc-containing wastes from the Mogilev “Khimvolokno” Industrial Association.
