It is estimated that about two-thirds of the US ...


  • Project (in process) - thunderbird farms - Arizona arsenic & fluoride removal

    Background In 2008 AdEdge was selected by Atwell Hicks Engineers and Thunderbird Improvement district to provide a 500 gpm treatment system for this Arizona community serving 1,500 population to treat elevated levels of arsenic and fluoride. Non compliant levels are 13 ppb As and 3.20 mg/L F respectively. Raw water quality information is provided in the table below. Several options were ...

  • Thermoplastic Water System

    The use of thermoplastic plastics in pharmaceutical and biotech water and process systems is gaining greater acceptance. Water systems are often more efficiently operated when thermoplastics such as Polyvinylidene Fluoride (PVDF) and Polypropylene (PP) are employed as compared to ones constructed of stainless steel. It is important to consider the unique properties of thermoplastics when ...
