    Pool Water Testing / Spa Water Testing

    Anyone and everyone who is responsible for operating and maintaining a swimming pool or spa has to test, monitor, and control complex, interdependent chemical factors that affect the quality of water bathers are immersed in. Additionally, aquatic facilities operators must be familiar with all laws, regulations, and guidelines governing what these parameters should be.

    Oxidation Reduction Potential (ORP)/Redox

    Oxidation Reduction Potential or Redox is the activity or strength of oxidizers and reducers in relation to their concentration. Oxidizers accept electrons, reducers lose electrons. Examples of oxidizers are: chlorine, hydrogen peroxide, bromine, ozone, and chlorine dioxide. Examples of reducers are sodium sulfite, sodium bisulfate and hydrogen sulfide. Like acidity and alkalinity, the increase of one is at the expense of the other.

  • Water quality monitoring systems for public pools & sanitary

    Public health authorities in some countries regulate the quality of water in public pools and control water treatment tightly. A typical installation comprises several instruments with a common web-server for access via intranet or internet.

  • Industrial solutions for cooling water contamination

    Problem: Large quantities of water are used for cooling in industrial manufacturing. To prevent scaling, corrosion and biofilm in the cooling system, inhibitors and biocides are regularity dosed. Make-up water is continuously added to the system to balance the loss of water from evaporation. As water is added, the concentration of chemicals is diluted and the quality of water changes.

  • Cyanide Treatment with Hydrogen Peroxide

    Cyanides are used in a number of chemical synthesis and metallurgical processes (as simple salts or cyanide complexes). As a class, cyanides are highly toxic and must be destroyed or removed from wastewaters prior to discharge. The most common method for treating free or simple cyanide is alkaline chlorination. However, chlorination of cyanide results in highly toxic intermediates (e.g., cyanogen chloride) and, if organic material is present, chlorinated VOC’s. These compounds, together with the residual chlorine, create additional environmental problems. Consequently, there is a growing need for alternative, non-chlorine methods for destroying cyanides. Peroxygen compounds such as hydrogen peroxide, peroxymonosulfuric acid (1), and persulfates (1) are effective alternatives to alkaline chlorination for destroying free and complexed cyanides. The choice of peroxygen system depends on the reaction time available, the desired products (cyanate, or CO2 and NH3), the types of cyanides being treated (free, weak acid dissociable, or inert), and the system economics. Treatment with Hydrogen Peroxide While hydrogen peroxide will oxidize free cyanide, it is common to catalyze the reaction with a transition metal such as soluble copper, vanadium, tungsten or silver in concentrations of 5 to 50 mg/L (2).

  • Water quality monitoring systems for portable water plants

    Low maintenance and reliability are key requirements for analyzers in potable water plants. Cost of ownership is another big issue.

  • Water quality monitoring systems for high water purifier industry

    The monitoring of “Ultra Pure Water” or “High Purity Water” requires the lowest possible detection limits for process analyzers. Resistivity is often around 18 MΩ. Dedicated instruments can detect infinitely small amounts (ppt e.g. parts per trillion) of ions.

  • Wastewater solutions for wastewater UV disinfection performance

    Problem: Prior to environmental discharge, wastewater is disinfected to ensure pathogens present in the water are inactivated. Ultraviolet (UV) disinfection is becoming a widely accepted treatment technology for wastewater disinfection due to the deleterious effects of chlorine on aquatic life. The ability for the UV light to penetrate the water is directly related to the concentration of suspended particles and organic matter in water that absorb or scatter the light.

  • Drinking water solutions for the TOC removal efficiency

    Problem: Organic matter (UV254/TOC) in drinking water can react with chlorine to form harmful disinfection by-products (DBPs). Some removal of TOC is achieved through the conventional drinking water treatment processes, while carbon absorption may be used to further enhance the removal of TOC prior to chlorine disinfection.

  • Odor Scrubbers Applications with Hydrogen Peroxide

    Hydrogen Peroxide as a Replacement for Sodium Hypochlorite Hydrogen peroxide may be used in both mist scrubbers and packed tower scrubbers as a replacement for sodium hypochlorite (bleach). Like bleach, the process involves two concurrent mechanisms: 1) absorption of the odors (H2S) into the alkaline scrubbing solution; and 2) oxidation of the absorbed sulfide in solution. Step 1: H2S + NaOH → NaSH + H2O Step 2: 4H2O2 + H2S → H2SO4 + 4H2O Typical dose ratios are 5 parts H2O2 per part H2S or, when used in place of bleach, one gallon 50% H2O2 for every 10 gallons of 15% sodium hypochlorite (NaOCl). This generally translates into a break-even cost scenario. Sufficient caustic soda (NaOH) is added to maintain a pH of 10.0 - 10.5 in the scrubbing solution. There is also in practice a process which uses H2O2 in series with bleach to scrub composting odors. This process relies on a series of three packed tower scrubbers: the first is a pH neutral water wash (to remove ammonia and amine odors); the second uses a conventional caustic/bleach solution in which the bleach is purposely overdosed (to oxidize the complex organic sulfur odors); and the third uses a caustic/H2O2 solution (to remove the unreacted chlorine vapors carried over from the second stage). H2O2 + HOCl → HCl + H2O + O2 Typical dose ratios are 0.5 parts H2O2 per part hypochlorite (OCl-), with sufficient caustic soda (NaOH) added to maintain a pH of 8.5 in the scrubbing solution.

  • Gas infusion technology solutions for the groundwater remediation areas

    Gas inFusion is a mass transfer operation whereby sparingly soluble gases are dissolved in liquids in a completely bubbleless fashion. The efficiency of this manner of mass transfer allows the production of stable liquid streams containing enormous quantities of dissolved gas on scales ranging from cc/min to thousands of GPM at a fraction of the energy cost normally associated with gas dissolution.
