  • Patent number: 10633263
    Abstract: A conventional media filter such as a gravity sand filter is converted into a membrane filter. The media is removed and replaced by immersed membrane modules. Transmembrane pressure is created by a static head pressure differential, without a suction pump, thereby creating a membrane gravity filter (MGF). Preferred operating parameters include transmembrane pressure of 5-20 kPa, 1-3 backwashes per day, and a flux of 10-20 L/m2/h. The membranes are dosed with chlorine or another oxidant, preferably at 700 minutes*mg/L as Cl2 equivalent per week or less. The small oxidant does is believed to provide a porous biofilm or fouling layer without substantially removing the layer. The media filter may be modified so that backwash wastewater is removed from near the bottom of the tank rather than through backwash troughs above the membrane modules. Membrane integrity testing may be done while the tank is emptied after a backwash.

  • Patent number: 10618828
    Abstract: An apparatus for reducing and inhibiting scale formation in water conduits is disclosed. The scale reducing apparatus has at least two stages, each stage containing one or more conduits therein surrounded by magnets. The magnets form a strong, substantially uniform magnetic field in the conduit(s) which is substantially perpendicular to the flow of water therein. Dissolved ions in the water interact with the magnetic field and may as a result be forced into contact with one another to form one or more non-dissolvable solids. The reduction in dissolved ions reduces and/or inhibits the formation of scale in the water supply lines of a structure, thus increasing the life of the conduits, appliances, and other structures where scale may form.

  • Patent number: 10569199
    Abstract: A filter frame, a filter cartridge, and an assembling method of the filter cartridge are provided. The method has the following steps. A filter core and a filter frame are prepared. The filter frame has a glue-cutting segment. Glue is coated around an outer wall of the filter core, and then the filter frame, which is mounted around the filter core, is pushed toward the glue to make the glue-cutting segment press the glue until the glue is cut into two parts. The inner glue part disposed between the filter core and the filter frame seals the filter cartridge. The outer glue part is disposed on an outer side of the filter frame, and is superfluous and removed. The glue-coating is combined with the mounting of the filter frame, thereby saving time and effort.
