  • Patent number: 11724948
    Abstract: Increased control and efficiency over the wastewater purification can be achieved through creating conditions that allow the operator to selectively prioritize the digestive function of microorganism in the activated sludge. The gas-dispersion return sludge is created using pure oxygen or oxygen containing trace amounts of ozone as a reactive gas, which is blended with return sludge to create a mixture of gas and liquid, which is passed through an atomizer or a cavitation pump to instantly render the reactive gas to an ultra-fine bubble state. At least a portion of the ultra-fine bubbles dissolve within the gas-dispersion return sludge, activating the dormant microorganisms. Due to a complete or an almost complete absence of biodegradable material in the gas-dispersion return sludge, the microorganism prioritize their digestive function, and when exposed to biodegradable pollutants present in wastewater, digest the pollutants using biochemical pathways different from the ones used in nature.

  • Patent number: 11668213
    Abstract: An apparatus and a method are provided for a high capacity oil filter configured to remove contaminants from engine oil flowing within an internal combustion engine. The oil filter comprises a hollow canister having a length and a diameter suitable for housing a large filtration medium. A base gasket forms a fluid-tight seal between the oil filter and the engine. A base plate circulates oil from the engine through the oil filter. An anti-drainback valve prevents oil from draining out of the filter and passages within the engine when the engine is not operating. A key aspect of the present disclosure is that the relatively large dimensions and the configuration of the filtration media provide a large surface area for entrapping contaminants flowing with the engine oil.

  • Patent number: 11618702
    Abstract: By completely removing the gas dissolved in the water, the ultra-high-pressure collision between the water flows is realized. This ultra-high pressure collision not only breaks the hydrogen bond between water molecules, but also breaks the structure of water molecules, making water (H2O) instantly become H+, OH?, O? ionic state, or even become independent hydrogen atom (H) and oxygen atom (O) states, and then return to the normal water molecule (H2O) state in an instant. By maintaining high pressurized state (maturity), stabilize the link between above-mentioned original water molecules (H2O). Through above-mentioned process of instantaneous breaking and instantaneous recovery, every water molecule is caused to become full of activity.
