  • Combination carrier granules
    Patent number: 5169644
    Abstract: New combination carrier granulars are disclosed which comprise a granular carrier material having a compact surface and having applied thereto at least one liquid biocidally active compound, at least one solid biocidally active compound, polyvinyl acetate and polyvinyl alcohol. These combination carrier granules exhibit unexpectedly better activity than prior art materials and have unexpectly high abrasion resistance.

  • Process for purifying waste water
    Patent number: 4663047
    Abstract: The purification process is carried out in two stages. In the first stage, pulverulent active carbon in finely-divided form is added to the waste water. The solids materials are then separated by conventional mechanical separating processes. The liquid phase prepurified in this manner is then allowed to trickle in a second stage through an active carbon adsorption tower, air being forced at the same time through the adsorption tower. The process has proved particularly valuable in the purification of pesticide-containing waste water.
