  • An antimicrobial polycationic sand filter for water disinfection

    A new sand filtration water disinfection technology is developed which relies on the antimicrobial properties of hydrophobic polycations (N-hexylated polyethylenimine) covalently attached to the sand's surface. The efficacy of the filter disinfection process was evaluated both with water spiked with E. coli and with real aqueous effluent from a wastewater treatment plant. For the ...

  • Ion Exchange Systems.

    When properly applied, ion exchange for concentrated ion recovery is by far the best available technology. Where effluent streams can be filtered and ions requiring different regenerants can be segregated, ion exchange is usually the most cost effective and least capital intensive solution. We provide 4 levels of integration to cover most applications and capital budgets. The variations in the ...

  • Reverse Osmosis: How Does It Figure Into a Dialysis Water System?

    Better than 95% of all dialysis centers use water purification equipment to purify water for dialysis. The centerpiece of these water purification systems has become reverse osmosis. In conjunction with sound pretreatment, RO has proven itself to be the safest, most reliable, and most economical method of purifying water for dialysis. Water plays an important, life-sustaining role for dialysis ...

  • Crossflow Membrane Filtration High-Purity Water Systems

    INTRODUCTION As the electronics industry continues to provide us with such products as high resolution television, notebook size portable computers and cars with automatic navigation systems, it becomes necessary to produce semiconductors with finer device geometries to allow for efficient placement of more circuits per a given area. This requires increased control of a semiconductor's material ...

  • Profile of Ozone/Bromine Sanitation Systems for City of Tucson Municipal Pools

    Due to the inherent risks associated with the use of chlorine gas as a sanitizer for the City of Tucson’s twenty-six municipal swimming pool sites, I found myself in search of an alternative water sanitation method. The challenge was clear; find a system that would be safer to manage than gas chlorine, yet yield the same favorable sanitation and water quality results. Since all the sites ...
