View Full Case Study Problem A Kansas manufacturing plant was forced to shut down after unusually high sodium levels in the Kansas River led to increased salinity in city water. Conductivity of the city water also increased from 500 µS/cm to 1,600 µS/cm. This heightened water conductivity was problematic during the rinsing process as it […]

View Full Case Study Problem A North Dakota power plant was not running at full capacity, which caused a water imbalance. This condition led to evaporation pond levels rising to near-overflow conditions. Plant personnel were concerned they could be put in a situation where any overflow would have violated EPA regulations, which could have led […]

View Full Case Study Problem For years, springtime had presented a distinct challenge for a large chemical-production complex in Alberta, Canada. With rain and melting snow, the facility could not handle the resulting high turbidity and TOC (Total Organic Carbon) in its feed water. Because of the elevated TOC levels, the facility was forced to […]
