  • Patent number: 11326362
    Abstract: A floatation accessory for a pool vacuum is an apparatus that maintains an inverted position for a pool vacuum such that the mouth of the pool vacuum suctions debris along the surface of a pool. The apparatus includes a support platform, a first float, a second float, a support ridge, a handle, an elongated guard, and a suspension system. The support platform upholds the first float and the second float. The first float and the second float are used to float a pool vacuum that is engaged with the apparatus. The support ridge connects the first float and the second float and offsets the elongated guard from the mouth of a pool vacuum. The elongated guard offsets the mouth of a pool vacuum from the side walls of a pool. The suspension system loops a pool vacuum with the support platform, and consequently the first float and the second float.

  • Patent number: 11319230
    Abstract: An apparatus for treating municipal sewage by anaerobic/aerobic/anoxic (AOA) [1] process via simultaneous endogenous partial [2] denitrification coupled with anammox in anoxic zone is disclosed. The apparatus mainly includes a raw water tank (1) for sewage, an AOA reactor (2) and a sedimentation tank (3), the sludge flows back from the bottom of the sedimentation tank (3) to the anoxic zone (2.4) and the anaerobic zone (2.2) respectively, and biofilm filler is added to the anoxic zone (2.4). The sewage enters the AOA reactor (2), and the intracellular carbon source is stored in the anaerobic zone (2.2) to remove the organic matter in the raw water. Then it enters the aerobic zone (2.3) for nitrification, and the generated nitrate-nitrogen enters the anoxic zone (2.4) for endogenous partial denitrification. The filler in the anoxic zone (2.4) uses the generated nitrite-nitrogen by endogenous partial denitrification and the remaining ammonia-nitrogen in the raw water to perform anammox reaction.

  • Patent number: 11286186
    Abstract: A method for treating dye wastewater includes: firstly, homogenizing the dye wastewater to balance the quality of the dye wastewater from different processes; then subjecting the homogenized dye wastewater to anaerobic treatment to remove most of chemical oxygen demand (COD) and total suspended solids (SS) in the wastewater; and finally subjecting the dye wastewater after the anaerobic treatment to circulating anaerobic-oxic treatment in a membrane bioreactor (MBR). In the present invention, the MBR is filled with a quinone-based hollow fiber membrane. The quinone acts as an electron mediator to accelerate an enzymatic reaction for dye decolorization during the anaerobic process, thereby achieving the purpose of efficient decolorization. The oxic treatment process further removes the COD and SS in the wastewater, so that the effluent meets a first-level discharge standard.
