  • BIOPOLYMER EXTRACTION
    Publication number: 20170088637
    Abstract: In a prior art reactor set up dense aggregates of microorganisms are formed, typically in or embedded in an extracellular matrix. Such may relate to granules, to sphere like entities having a higher viscosity than water, globules, a biofilm, etc. The dense aggregates comprise extracellular polymeric substances, or biopolymers, in particular linear polysaccharides. The present invention is in the field of extraction of a biopolymer from a granular sludge, a biopolymer obtained by such method, and a use of such method.

  • Method for the treatment of waste water with sludge granules
    Publication number: 20060032815
    Abstract: The invention relates to a method for the treatment of waste water comprising an organic nutrient. According to the invention, the waste water is in a first step fed to sludge granules, after the supply of the waste water to be treated the sludge granules are fluidised in the presence of an oxygen-comprising gas, and in a third step, the sludge granules are allowed to settle in a settling step. This makes it possible to effectively remove not only organic nutrients but optionally also nitrogen compounds and phosphate.
