  • Binary vs Quaternary Pumps

    How is a Gradient Created? Any liquid chromatograph is an amalgamation of a certain set of components that delivers to the scientist a monograph of the sample they are analyzing.  Traditionally, an LC system consists of a pump, an injector, a column heater, a detector and even more commonly these days a mass spectrometer or mass detector.  In ...

  • Destabilization dynamics of clay and acid-free polymers of ferric and magnesium salts in AMD without pH adjustment

    The physicochemical treatment was employed to treat acid mine drainage (AMD) in the removal of turbid materials using clay only (exp A) and a combination of clay, FeCl3 and Mg(OH)2 (exp B) to form a polymer. A 5 g sample of clay (bentonite) was added to 1.2 L of AMD and treated in a jar test at 250 rpm for 2 min and reduced to 100 rpm for 10 min. A 200 mL sub-sample from the 1.2 L mother ...

  • A parametric study of alum recovery from water treatment sludge

    Alum recovery from water treatment sludge is a promising technique applied to decrease usage of fresh coagulants in the water treatment industry. In addition, alum recovery reduces sludge volume for easy handling. The undertaken work investigated the parametric conditions for alum recovery procedure by acidification. The results show that alum recovery reaches up to 69.03%, and the reduction ...

  • ACQUITY Arc System: Transferring Validated HPLC Methods within USP Guidelines

    The thought of transferring established high performance liquid chromatography (HPLC) methods onto a another vendor’s LC, or a new platform like UHPLC/UPLC, may cause a bit of anxiety for those that may be unaware of how easy it can be. The reason that the topic of analytical method transfer induces so much angst is that for the transfer of an LC method to succeed, the method has to work as ...

  • Savanna wastewater treatment plant case study

    Performance History and Discussion Jackson, MS selected In-Pipe Technology Company, Inc. for the Savanna WWTP with goals to reduce the quantity of waste sludge for disposal and control FOG in the collection system and at the plant. Jackson, the capital and largest city in Mississippi, was looking for ways to reduce sludge expenses from polymer to hauling and disposal fees. In-Pipe ...

  • WWTP Sludge reduction case study

    Introduction The City of Spring Valley, IL was seeking bioaugmentation to reduce the economic burden of sludge dredging and disposal and to evaluate the possibility of restoring the microbiological activity in the lagoon. The lagoon was flooded several times from the near-by Illinois River, which created different strata of inorganic silt/organic sludge and densely packed sludge at the ...

  • WEFTEC’ 2013 Lagoon wastewater treatment using Innovative bioaugmentation technology case study

  • The design of static mixer heat transfer equipment for adhesives, sealants, resins and polymers.

    The fluids handled within the adhesives and sealant industries are amongst the most difficult to handle of any in the main process industries globally. The characteristics which make them particularly difficult to handle include: High viscosities (typically 1-2000 Pa.s, or 1000 to 2 million cP). Often non-Newtonian (viscosity is not constant and varies with shear rate). Some ...

  • Discrete mixed subdomain least squares (DMSLS) meshless method with collocation points for modeling dam-break induced flows

    This paper presents a new meshless numerical scheme to overcome the problem of shock waves and to apply boundary conditions in cases of dam-break flows in channels with constant and variable widths. The numerical program solves shallow water equations based on the discrete mixed subdomain least squares (DMSLS) meshless method with collocation points. The DMSLS meshless method is based on the ...
