  • Confirmation of the correlation between membrane fouling in microfiltration and biopolymer concentrations in various Japanese surface waters

    A variety of surface waters used for drinking water sources were collected from different parts of Japan to investigate a correlation between the concentration of hydrophilic biopolymer (e.g. proteins and polysaccharides) in the feed water and membrane fouling in microfiltration. Hollow-fiber membranes made from polyvinylidene fluoride with a nominal pore size of 0.1 μm were used in the ...

  • Case study - N°NG1 – Natural gas monitoring – Medor Exp

    Context & Challenges Natural gas used for household consumption typically contains odorant sulfur components for safety reasons. As natural gas is normally odorless, the sulfur components are artificially added. When natural gas is transported between various companies, regions or countries, gas companies have to verify that the sulfur species are present as specified. ...

  • Glyphosate and AMPA in drinking water

    Carcinogenic or not? The broad-spectrum herbicide glyphosate is used all over the world in agriculture. Alongside farming, the chemical is also used for weed-killing in domestic gardens and in public and private spaces kept free from «vegetal invasion», such as railway tracks. Glyphosate has been used since the 1970s in pesticides and was hitherto thought to be harmless at ...

  • Case study - N°AA2 – Ambiant air monitoring – WWP TRSMEDOR deodorisation

    Context & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® ...

  • Smart Infrastructure is Key for QA/QC

    Paperless, or more accurately integrated, labs enjoy streamlined operations with better data, while minimizing costs, validation and maintenance. Laboratories responsible for QA/QC are a sum of many parts, but no part is more important than data. Data is THE product, and the integrity of that data is more than critical to today’s pharmaceutical laboratories. So what happens when processes ...
