Abstract: A process for the aeration of wastewater employs an aerator comprising a porous body having an average pore size from 5 to 250 μm produced by sintering a composition comprising polyethylene particles having a molecular weight of at least 3×105 g/mol as determined by ASTM-D 4020 and a weight average particle size, D50, from 20 to 650 μm. The porous aerator is provided in the wastewater and an oxygen-containing gas, such as air, is passed through the porous aerator into the wastewater to assist in purification of the wastewater.
