hardness test Applications

  • Phosphonate Testing in Hard Water

    Testing phosphonates in hard water can be difficult due to interference from high levels of calcium. Here we present a phosphonate test method for hard water samples. The method is based on a chemical masking of the calcium. The WAT hard water phosphonate test uses C30 Spectrophotometer to measure the chromogen PMB and digital thermoreactor to digest the phosphonate compound. The thermoreactor capacity of 16 simultaneous vials provides for running critical data quality assurance samples.

  • SONARtrac - Dredging - Hopper Vessels

    Soil density, hardness, lithology, and sediment particle size distribution can create slurry of variable makeup and density. At a constant pump speed, the slurry will have a variable flow velocity, which is undesirable and potentially dangerous. If the velocity is too low, there is a risk of sand outs in the pipeline. If the velocity is too high, the pump will wear and be inefficient. Traditional velocity flow meters with wetted parts are prone to wear, causing measurement inaccuracies, and require frequent, costly replacements. In addition, the presence of entrained gases may disturb the readings of traditional flowmeters and cause slurry density measurements to be inaccurate.

  • Monitoring surface water for wastewater treatment industry

    Pollution Risk: Surface water encompasses storm water derived from hard standing areas, river water and reservoirs. All types of surface water are at risk from ingress of pollution and therefore need to be monitored. On-line continuous monitoring can identify and alarm pollution so corrective action can be taken
