  • METHOD AND SYSTEM FOR CONTROLLING HYDROPHOBIC CONDITIONS AND FOULING IN WATER INTENSIVE PROCESSES
    Publication number: 20240092668
    Abstract: In a water treatment system, a pretreatment chemical is added to water stream in a pretreatment process including a coagulation, flocculation and separation to reduce amount of dissolved and/or particulate matter in the water stream. Hydrophobic conditions in the water stream are monitored upstream or downstream from adding the pretreatment chemicals. Dosing of the pretreatment chemical to the water stream is controlled based on the monitored hydrophobic conditions. Thereby a membrane fouling in subsequent membrane filtration stage can be minimized.

  • Method for detecting transparent exopolymer particles in a water sample
    Publication number: 20160202189
    Abstract: Method for detecting transparent exopolymer particles in a water sample. The method comprises step of obtaining a water sample and introducing a fluorochromatic reagent to the water sample. The fluorochromatic reagent is specific to vicinal hydroxide groups of transparent exopolymer particles, whereby the fluorescence signal of the reagent changes when it comes into contact with transparent exopolymer particles, i.e. TEP. Finally the fluorescence signal from the water sample is detected and the TEP level of the sample is determined.
