摘要： The present invention provides a magnetic biochar-quaternary phosphonium salt bactericidal material, a preparation method therefor and usage thereof, and belongs to the field of water treatment. The preparation method comprises: 1) using corn straw biochar as a precursor to prepare magnetic biochar by a co-precipitation method; and 2) adding the magnetic biochar into deionized water, then adding a quaternary phosphonium salt, performing the magnetic stir at room temperature, raising the temperature after sufficient impregnation, carrying out a hydrothermal reaction, and then cooling to the room temperature to obtain the bactericidal material. The temperature is raised to 60° C.˜70° C. The recycling of the biochar material is effectively realized, the long-acting sterilization of the quaternary phosphonium salt bactericide and the magnetic recovery and recycling of the materials are realized, the residue of the bactericide is reduced, and a foundation is laid for the effective removal of microorganisms in wastewater.

摘要： Devices, systems and methods for removing minerals from a conductive protonic fluid and creating oxidizers therein. A non-alternating flow of electrons in a conductive protonic fluid selectively precipitates hardness causing heavy minerals from the fluid. The decrease in hardness causing minerals leads to the protonic fluid moving towards a thermodynamic equilibrium that prevents precipitation of the noted hardness causing minerals. By-products from the process, like halogens, help oxidize other minerals and treat bio-life within the source. Systems include a vessel containing the conductive protonic fluid, a conductive protonic fluid flow mechanism, a power supply, a control mechanism, and one or more reaction chambers. The reaction chamber has at least one reaction chamber wall having a conductive surface and a conductive element. The power supply provides an electric field to the conductive protonic fluid in the reaction chamber such that the conductive surface and the conductive element have opposing charges which separate the conductive protonic fluid into negative and positive ions creating an ion gradient between the conductive element and conductive surface, resulting in a pH gradient between the conductive surface and the conductive element, thereby enhancing precipitation of the minerals on a positive end of the ion gradient.

摘要： Membrane filtration systems can be used to purify liquid streams for downstream use. In practice, foulant can build-up on the surface of a membrane within a filtration system over time. The effectiveness of the filtration system will deteriorate if the fouling is not properly controlled. In some examples, a method of controlling membrane fouling in a pressurized membrane system involves supplying a feed stream that is predominately air mixed with water to the membrane. In other words, the feed stream a greater volume of air than water, even though it is the water being processed by the membrane. Supplying the pressurized membrane system with a feed stream that contains a greater volume of air than water can yield significantly better performance than supplying the membrane with a feed stream that contains a greater volume of water than air.

摘要： A wastewater management system includes a series of water treatment modules to treat wastewater and produce reusable and/or potable water and other beneficial byproducts of the wastewater treatment process. A pretreatment module, a filtration module, an evaporator module, an odor control module, a UV-light module, an autoclave module, a sonolysis module, an ozone module and a chlorination module are combined in multiple combinations along with holding tanks, condensers, flash tanks and other components to address water purification and reclamation needs based upon specific wastewater conditions. The system captures condensate from AC systems and rainwater from rainwater gutter systems processes the water to produce reusable and/or potable water with or without re-mineralization. Any CO2 produced by the water treatment system is captured and processed using naturally-occurring flora. The wastewater treatment system includes multiple closed-loop subsystems to minimize energy usage and maximize water purification and reclamation for reuse.

摘要： A method of controlling cooling water treatment at a cooling tower may involve measuring operating data of one or more downstream heat exchangers that receive cooling water from the cooling tower. For example, the inlet and outlet temperatures of both the hot and cold streams of a downstream heat exchanger may be measured, optionally along with a flow rate of the cooling water stream passing through the heat exchanger. Data from the streams passing through the heat exchanger may be used to determine a heat transfer efficiency for the heat exchanger. The heat transfer efficiency can be trended over a period of time and changes in the trend detected to identify cooling water fouling issues. A chemical additive selected to reduce, eliminate, or otherwise control the cooling water fouling can be controlled based on the changes in heat transfer efficiency detected at the downstream heat exchanger.
