Second installment of an article on water purification for textile mills, from Posselt's Textile Journal, November 1907. It covers removal of suspended impurities by plain sedimentation and by coagulation with alum or sulphate of alumina, including the chemical reactions and a table of suspended matter removed over time. It then explains sand filtration, from a simple home-made tank filter to patent self-washing filters with valve control and automatic alum feed.
