  • Patent number: 10941065
    Abstract: This combined dehydration device continuously supplies primarily dehydrated sludge to a sludge supply part, the combined dehydration device including: a multiple rotary disk-type solid-liquid separation device and an electroosmosis dehydration device. In the multiple rotary disk-type solid-liquid separation device, a plurality of rotary shafts in which a plurality of rotary disks are fitted and mounted are arranged from the upstream side toward the downstream side and pivotally supported; while the rotary disks are rotated, water to be treated including sludge is supplied from over the rotary disks at the upstream side and is subjected to a primary dehydration treatment; and first dehydrated sludge on the rotary disks is fed and discharged from a sludge discharge part located at the most downstream portion of the rotary disks. In the electroosmosis dehydration device, a sludge supply part is provided at the upstream side of an endless filtration fabric spread between rollers.

  • Publication number: 20210030934
    Abstract: Disclosed is a milk suction and collection device integrally manufactured and formed by silicone. The milk suction and collection device includes a main body which is hollow inside to define a milk storage chamber and is further provided with a milk pouring port operative to be selectively blocked. A breast protecting film is provided on a side in a thickness direction of the main body and is configured to be fitted with an outer periphery of a breast, and is further provided with a milk collecting port communicating with the milk storage chamber. The side of the main body of the milk suction and collection device provided with the breast protecting film is operative to be fitted with the breast because the milk suction and collection device is integrally manufactured and formed by silicone. When the milk pouring port is closed, a breast pumping function is achieved by squeezing the main body. When the milk pouring port is opened, a milk collecting function is achieved.

  • Publication number: 20200222285
    Abstract: A breast pump comprising: a container comprising a deformable body and a lid, the container further comprising an inlet and a vent, wherein the vent is provided with a vent valve which is configured to allow air flow out of the container through the vent but not into the container through the vent; a nipple shield for receiving milk expressed from a user's breast; and a flexible conduit fluidly connecting the nipple shield and the inlet of the deformable container, wherein, in use, milk expressed from the breast flows from the nipple shield through the conduit to the container.

  • Patent number: 6773597
    Abstract: The invention offers a method and apparatus for solubilizing excess sludge, having a high solubilizing ability, a low total cost, and capable of reducing the size of facilities. The method for reducing excess sludge comprises adding a solubilizing agent to excess sludge generated by microbial treatment of organic sewage, applying ultrasonic waves, applying a reduced pressure swelling step, then returning the result to the microbial treatment, whereby the volume of the excess sludge can be reduced. The apparatus for reducing excess sludge comprises means for adding a solubilizing agent to excess sludge generated by applying a microbial treatment to organic sewage, ultrasonic wave applying means for applying ultrasonic waves, and reduced pressure swelling means provided downstream of the ultrasonic wave applying means for applying a reduced pressure swelling process to the excess sludge.
