HaloSense Zero

Key Benefits
Many water companies want to measure free chlorine residuals without the need for chemical buffers traditionally associated with such measurements. Acetate and phosphate buffers are expensive and environmentally unfriendly. Buffer delivery systems are maintenance intensive and have fairly costly consumables and there are health and safety considerations in the handling of the acids and high disposal costs if the acid treated water is unable to be fed back into the water supply. Amperometric cells and most polarographic probes only respond to hypochlorous acid, (HOCl). HOCl dissociates into hypochlorite (OCl–) in a pH dependent manner. This is why most chlorine monitors need acid buffers in most applications. The typical pH of water measured on a water treatment works may range from 7 to 9.2. Chemical buffering reduces the pH to between 5 and 6 and ensures that the majority of the residual chlorine is present as HOCl (see graph below).
  • Low purchase cost
  • Low cost of ownership
  • Reduced pH dependency (largely pH independent)
  • Stable and reliable
  • Bufferless
  • Reagentless

UV254Sense

Key Benefits
  • UVA (ultra-violet absorbance) is an excellent surrogate parameter for TOC, DOC, COD and color.
  • UVT (ultra-violet transmission) allows for the calculation of optimal UV dose for disinfection systems, improving efficiency.
  • Accurate detection without the cost of reagents.
  • Few ongoing service or maintenance requirements.
  • Allows feed forward optimization of coagulation control, resulting in decreases in chemical consumption, reduction in sludge removal costs and minimization of DBP formation potential.
  • Strong ROI with pay back on the analyzer being seen by many customers within a few months.
  • UVA measurement ensures performance of various contaminant removal technologies such as membranes (RO, NF, UF), ion exchange (nitrates and TOC removal) and granular activated carbon (GAC).
  • Real time UVA analyzers can provide a final check of effluent water quality and can alarm an operator in case of non-compliance.
  • A UVA monitor can monitor the percentage removal of organics across any treatment system.
  • Can be combined with a CRONOS® or CRIUS® for a multi-parameter UV254 analyzer solution that suits your needs.
  • Standard Features
  • Online continuous operation

    AquaSense

    Swimming pools and spas use chlorine as a disinfectant and so use an analyzer to control the amount of chlorine that gets dosed. The AquaSense Swimming Pool Controller and Spa Controller measures the pool chlorine levels and the pH of the pool and then controls the chlorine and pH levels by controlling the chemical dosing. The AquaSense offers bufferless and reagentless operation and is suitable for commercial, municipal and community swimming pools. The AquaSense has been designed to three criteria:
    • Improved Safety – better sensors lead to better process control which leads to less variation in chlorine residuals even with highly variable bathing load.
    • Improved Control – better process control leads to reduced chemical usage, lower costs and an improved bathing experience.
    • Reduced Costs – lower chemical costs, less expensive controllers, inverter control leading to hugely reduced electrical usage costs are just a few of the ways that the AquaSense can save you money which can pay for a new controller in just a few months.
    Key Benefits
    • Inverter control for massive electricity and CO2 savings
    • Stable and reliable residual chlorine and pH measurement and control
    • Low purchase cost
    • Low cost of ownership
    • SMS text alarms
    • Remote access via Internet
    • Suitable for fresh water, salt water and outdoor pools with cyanuric acid
    • Private label option for re-sellers
    • Other inputs to data log and alarms
