  • Why evaluate hydraulic fluid compatibility?

    When introducing a new control fluid to hydraulic systems, it is important to ensure that the new liquid or mixture is of equal or superior quality to the previous fluid. If the new mixture is incompatible, precipitate may form and result in an overall inferior fluid. This can speed up clogging or damage the system. When a manufacturer of construction machinery releases a new line of bulldozers ...

  • Pilot Study Application of Tertiary Clarification and Filtration to Meet Proposed Ultra Low Phosphorous Discharge Limits on The Spokane River

    The Spokane River flows through northern Idaho and eastern Washington. The Washington State Department of Ecology is proposing to implement an interim phosphorous TMDL (total maximum daily load) of 50 ppb, and a final TMDL of 10 ppb on all point source discharges to the river. Biological treatment alone is not sufficient to meet these levels, requiring the addition of tertiary physical/chemical ...

  • Dual layer hollow fiber PVDF ultra-filtration membranes containing Ag nano-particle loaded zeolite with longer term anti-bacterial capacity in salt water

    Dual layer polyvinylidene fluoride (PVDF), antibacterial, hollow fiber, ultra-filtration composite membranes with antibacterial particles (silver (Ag) nano-particles loaded zeolite (Z-Ag)) in the outer layer were prepared with high water flux and desired pore sizes. The amounts of Ag+ released from the composite membranes, freshly made and stored in water and salt solution, were measured. The ...
