Abstract

The invention relates to a purification composition comprising: a. 2-20 wt. pcnt , calculated by weight of dry matter, of an aluminium chlorohydrate compound, having a basicity in the range of 60 pcnt -85 pcnt ; b. 2-20 wt. pcnt , calculated by weight of dry matter, of an iron flocculant; c. 0.1-5 wt. pcnt , calculated by weight of dry matter, of an anionic polyacrylamide having a molecular weight of more than 100 kDa; d. 40-96 wt. pcnt , calculated by weight of dry matter, of a particulate filler; wherein the dry weight ratio of the aluminium chlorohydrate to the iron flocculant lies in the range of 1:1 to 1:5. The invention further relates to a method of clarifying soiled water for obtaining clarified water suitable for use in laundry.
