Research in Coagulation Properties of AQUA-AURAT™18 and Aluminium Sulphate at Independent and Combined Application

Summary

Results of the experimental studies on coagulation of pollutants of various types (suspended substances, dyes and humic substances) with coagulant AQUA-AURAT™18 and aluminium sulphate at combined application depending on their ratio and order of insertion in comparison with composite coagulant AQUA-AURAT™105 are presented. It is shown, that the combined use of aluminium sulphate and AQUA-AURAT™18 at consecutive insertion or in the form of composition intensifies the process of water treatment for suspended and dissolved acid substances (humates and acid dyes) comparing with the independent use of coagulants at a lesser or equal dose. The composite coagulant AQUA-AURAT™105 is more efficient for removal of suspended substances from wastewater than dissolved organic pollutants of acid type.
