  • pH Tech Tips (.pdf)
    The Concentration ratio of hydrogen ions (H+) and hydroxyl ions (OH-) determine the pH value of a solution. Any hydrogen activity will produce a 59.16 mV/ pH unit across the glass membrane. The measurement is expressed on a scale of 0.0 to 14.0. Water with a pH of 7 is considered neutral (H+ ions
  • Amperometric Free Chlorine Measurement without pH Compensation
    Accurate measurement and control of free chlorine in water is critical in many applications. Amperometric sensors are a popular alternative to colorimetric analyzers since the measurement is continuous and no reagents are required, however most sensors are extremely sensitive to pH fluctuations
  • Irrigation Water PH Cpntrol, Irrigation Water Disinfection, Fertigation
    applications. that utilize chemical pumps and controllers to accomplish this treatment. Irrigation Water pH Control. In many parts of the country hard, alkaline water is present in both surface and underground systems. The. hardness and alkalinity produce scale (calcium carbonate) in the sprinklers
  • Aggressive pH Monitoring for Aggressive Chemical Processes
    of the process, enough acid is charged into the vessel to achieve a 0.6 pH. Water is then added to dilute the organic level to allow pH measurement and to control impurities. Organic solvent is then used for the extraction of organic impurities. From this point, caustic is added to the aqueous phase
  • The Control of pH & Oxidation Reduction Potential (ORP) in Cooling Tower Applications
    control minimizes this problem. Similarly, the combination of pH control and ORP control can maintain chlorine and/or. bromine residuals at the levels required to inhibit survival of bacterium and the biofilm. that supports them. Maintaining a constant low-level halogen residual also minimizes
  • Mitigation of FOD and Corrosion Fatigue Damage in 17-4 PH Stainless Steel Compressor Blades with Surface Treatment (.pdf)
    Compressor blades of a military aircraft turbine. engine made of 17-4 PH stainless steel have. been reported to have blade edge foreign object. damage (FOD), corrosion pitting, and erosion. damage that reduce fatigue life. This paper. reports the findings of a comprehensive. investigation
  • ADSORBSIA TM Media Reduces Arsenic Levels at Emerald Well, providing potable water to Arizona Community (.pdf)
    of 17 ppb. Aquacell, Inc., was selected by Cold Water Canyon to design a water. treatment system to lower arsenic levels at Emerald Well based on the water. quality conditions, including the silica content and pH of the water, at the site. (see Table 1). Table 1. Water Conditions at Emerald Well
  • Use of industrial waste water
    Chemical Co, St Louis, MO, USA) as substrate. The biomass concentration was gravimetrically determined after centrifugation of 5 ml aliquots of the respective cultures, washing twice with distilled water and drying at 105oC to constant mass. 3.5 Xylanase Temperature and pH OptimaThe pH
