CA 2483501

There is provided purification techniques applicable to the aqueous suspensions in order to remove the suspended particles. The present invention deals with purification of aqueous suspension having essentially different nature and solid phase content in particular with purification of technological stream of the aqueous suspensions formed in chemical, coalmining, oil, ore, pulp and paper industries and others. The flocculant applied is treated by a mixture of surfactants: ethylene glycol monoalkyl ether or propylene glycol monoalkyl ether or propylene glycol and halogen hydrides of ethylene or halogen hydrides of propylene, olefin oxide or mixtures thereof. Intensification effect is created due to increasing flocculant molecular mass.
