Stainless Steel for Potable Water Treatment Plants (10087)
By R.E. Avery, S. Lamb, C.A. Powell and A.H. Tuthill. Types 304L and 316L welded stainless steel piping has been successfully used in over 100 PWTPs and related potable water applications in North America. The principal reason to use stainless steel is its outstanding resistance to contaminate potable water with metal ions. Stainless steel has been used since 1965 for the large, central-control, gravity filter in water treatment plants with good performance in over 75 installations.
