The invention relates to a process for treating sulphate-containing waste water (effluent) by addition of at least one precipitant. It is proposed to use as precipitant a water-soluble aluminate or an aluminate-containing substance. In a preferred embodiment of the invention, aluminate-containing aluminous cement and lime are added to the waste water. The process according to the invention produces a virtually sulphate-free waste water.
