A process is provided which can be used to treat aqueous streams comprising soluble biomaterials, especially proteins, wherein the concentration of soluble biomaterials is substantially reduced. The process comprises adjusting the pH of a substantially aqueous to less than or equal to pH 3 to produce a first pH-adjusted stream, which is in turn adjusted to greater than pH 3 to produce a second pH-adjusted stream followed by addition of a flocculant to produce a flocculated material.
