20150048013 | Fixed Bed for Aerobic or Anaerobic Wastewater Purification - The invention relates to a fixed bed for aerobic or anaerobic wastewater purification, comprising an upper frame having support elements fixed to opposite side rails and/or intermediate rails for attaching textile, foldable, non-degradable supports for microorganism, a lower frame having support elements for fixing the textile supports to the lower frame, and means connecting the frames at a corner region. The invention is a fixed bed where all parts of the fixed bed can be assembled to form a relatively small packaging unit that already contains the inserted textiles. Frames are provided with spacers at least in the corner regions, the height of which spacers corresponds to the material height of the folded supports between two frames and the supports are fixed by means of the supports members to the side rails and/or intermediate rails of the frames in a preassembly step before folding. | 02-19-2015 |
20150068960 | HIGH-CAPACITY BIOLOGICAL CONTACT ROTOR - The present invention relates to a shaft/frame system for high capacity rotors for wastewater treatment for sanitation purposes and to reduce the pollutant organic load; of the type formed by a drive shaft with supports at the ends and for its coupling to a drive motor, comprising a plurality of intermediate annular collars and two end annular collars distributed equidistantly from one another, adapted to fixedly receive a plurality of radially distributed structural arms, characterized in that said structural arms are substantially T-shaped and are joined each other to form rings adapted to receive and fix each other, packs of media consisting of a plurality of biomass support sheets, which are self-supported by four tubes fixed in T-shaped structural elements; wherein said tubes are hollow, and internally accommodate a volume of air and are obturated at both ends by means of plugs, with one or more threaded blind bore(s) adapted to receive the fixation means, with which it is fixed to the T-shaped structural elements, which exert a buoyancy force when turning the rotor by effect of the contained air. In addition to have elements that helps to the resistant bonding with reduced stresses in the T-shaped structure. | 03-12-2015 |
20150353398 | SYSTEM FOR WASTEWATER TREATMENT USING AQUATIC PLANTS - A wastewater treatment system includes a treatment zone having wastewater therein, the zone having multiple depths connected by slopes. Buoyant support structures are disposed in the treatment zone and receive aquatic plants. Hydraulic curtain assemblies are disposed in the treatment zone and define lanes in the wastewater environment. Biological curtains are connected to the support structures and have a body or material for formation of biofilms. | 12-10-2015 |

20160122214 | BIO-BLOCK - A bio-block has a main body provided with at least one through hole. The through hole foil is two openings in two surfaces of the main body respectively and has a diameter of 2.5±0.25 mm and a depth of 10.0±1.0 mm When the main body is immersed in a liquid, the surface tension or viscosity generated at the two openings of the through hole guides the liquid rapidly into the through hole and makes the liquid stay in the through hole without flowing through the through hole immediately. Thus, the bio-block retains the liquid in the through hole. The liquid in the through hole can be used to grow microorganisms or plankton such as bacteria, microalgae, and SS-type rotifers. Given the same volume, the bio-block can cultivate various microorganisms and plankton in larger quantities and at higher speed than similar products. | 05-05-2016 |
