Control of slime growth on process surfaces Slime formation on wet surfaces of a paper machine is often initiated by bacteria. In addition to microorganisms, older slime deposits usually contain fibres, pitch, fillers, pigments and other papermaking chemicals that have been trapped in the growing slime from process water continuously running next to the surface.
