"Complex" Pyridine [not simple PDADMAC.] Yael Mishael – Clay Polymer Sorbents for the Removal of Organic Micro-Pollutants (TTM:2876)– Prof. Mishael developed a patented clay based ‘pyridine’ composite to remove organic pollutants with a higher efficiency then activated carbon. The composite is cheap to produce yet highly effective in removing drugs, herbicides and pesticides. Patent Position: https://www.lens.org/lens/patent/WO_2016_151592_A1 Yissum Online: http://www.yissum.co.il/technologies/project/2876 Below thoughts were edited and approved by Yael Mishael: The complex pyridine based polymer is ‘designed’ for catching micro pollutants @ ng/Liter concentrations (single molecule - pharmaceuticals, herbicide, pesticide), but there are no regulations in place for treatment of micropollutants from waste water.  So there is no incentive for companies/municipalities to add expensive capex to treat this wastewater (capex for pumps, filtration columns etc – irrespective of adsorption resin). There is not really a need for filtering freshwater (tap water) through a complex resin since freshwater is not tested for micro pollutants and is not likely to have this and again there is no regulation for this.   On the other hand the simple ‘PDADMAC’ polymer can be used for filtering any dissolvable organic matter (humeric/muddy), and can be used for clearing up opaque fresh water prior to drinking or treated wastwater. So the results are clearly visible and can be used in municipalities and private home filtration systems, and it was found to be more efficient and more cost effective in purifying organic matter than granulated activated carbon.

The technology : Sewage Sludge Extraction (SSE)system for Sludge Dewatering and Thickening is a novel rotary continuous feed mechanical sludge compression devise that simultaneously sucks, and compress sludge mix, on opposite sides of its internal rotating element in a toroidal chamber, to segregate water and sludge into continuous out flow stream through separate channels. Unlike conventional compression technologies this is a ‘Continuous feed Type’ machine , compact, completely enclosed system (keeping sludge sealed from the operators environment to maintain odour free operations) that can operate within necessary power limits and fit within cylindrical space constraints as specified for the Omni -Ingestor to treat rates of 3 litres/higher per second within a compact toroidal chamber with self-cleaning separation screens membranes for long maintenance free operation. The system significant technical advancement and inventive step is that this system is 1st of its kind ‘Rotary Positive Displacement’ devise that permits variable volume control between its rotating elements to deliver a compact & highly efficient, simple continuous feed mechanical compression devise with capability for real time variation in the degree of compression based on the type of sludge and to self-adjust the compression ratio to deliver highly thickened sludge from range of inputs.
