  • Treating Industrial Water with Membrane Technology

    A variety of industries are finding that it makes sense to reevaluate the way they treat industrial process water, both to improve the quality of their products and increase the efficiency of their processes. Purification systems utilizing crossflow membrane filtration, such as reverse osmosis (RO), nanofiltration (NF) or ultrafiltration (UF) can be a good alternative to traditional filtration ...


  • Evaluation of UV System Performance and Challenges of UV Validation Testing at the Laguna County Sanitation District

    ABSTRACTThe Laguna County Sanitation District (LCSD) Water Reclamation Plant, with a design capacity of 3.7 mgd, produces tertiary water that was designed to meet California Title 22 unrestricted re-use criteria. The disinfection in LCSD is provided by an in-line Aquionics Model 7500 medium pressure UV system containing four UV banks. California Department of Health and Services (CDHS) require ...

  • Two Case Histories of Industrial Water Reuse Via Membrane Technology

    Abstract This paper describes two successful applications of ultrafiltration (UF) and reverse osmosis (RO) membrane technology used to reclaim water, reduce waste water discharge costs. The first case history covers oily waste water treatment at a major aluminum beverage can manufacturing plant. The second case describes treatment of waste water from a multi-plating bath section of a major ...
