The present invention relates to an apparatus for water descaling. The system comprises hydrodynamic cavitation reactors with a cavitator selected from the group consisting of an orifice plate, venturi and a rotating cavitator, in combination with an infrared radiation emitter. Combination of hydrodynamic cavitation reactor with infrared radiation achieves effective salt precipitation from the hard water with reduced pressure drop and reduced number of recirculation, resulting in higher savings due to reduced energy costs.

A system includes a cooling tower, an algae inhibitor skid, and at least one pump fluidly connected between the cooling tower and the algae inhibitor skid. The algae inhibitor skid includes a first water tank containing a first water supply fluidly connected to the cooling tower and barley straw suspended within the first water tank above the first water supply.

A water savings system and method for reducing the amount of water needed for adiabatic cooling including the use of a softener and a reverse osmosis device, in which tap water, softened if necessary, is delivered to a reverse osmosis device and softened water alone, reverse osmosis reject water, or softened water combined with reverse osmosis reject water is delivered to spray nozzles for cooling, and reverse osmosis pure water is stored and used periodically to flush the coils to inhibit and/or prevent corrosion from dissolved salts and other solids in the spray water.

Some implementations of the present disclosure prevent, reduce or at least slow equipment fouling using passivation as a treatment prior to contacting metallic components with hydrocarbon containing fluid, that is, an environment where fouling occurs. For example, one implementation includes a method of passivating heat exchangers in a SAGD process or system using the compositions and compounds of the present disclosure. The composition may be applied to a component prior to its first inclusion in an online system or following placing the system offline for maintenance. The composition may be used to treat metallic equipment surface(s), for example, via contacting them with a suspension or solution of the composition described herein, prior placing the system online. The method may further include treatment of the process fluid, for example, via injection or batch treatment of the composition with the compositions described herein into the process fluid.

A method of reducing activity of sulfur and/or nitrogen metabolizing bacteria is provided. The method includes adding a composition of an alkali metal salt of chlorite and/or an alkali metal salt of chlorate and hydrogen peroxide to process water of a cooling tower and increasing a concentration of the composition from about 0 ppm to about 300 ppm in about 1 to about 100 minutes. The method results in significant savings of caustic and reduces sulfur and/or nitrogen metabolizing bacteria in the process water.

A method for differentially lysing a liquid sample or target material using an augmented oxidizing agent (AOA), which includes a quantity of electronically modified oxygen derivatives (EMODs). The method reduces or eliminates total dissolved solids (IDS), total suspended solids (TSS), Biologic Oxygen Demand (BOD), microbial concentration, biofilms and other content in the liquid target material known or suspected to contain animal fluids, blood and blood cells and suspected or known to contain eukaryotic cells, microbial cells, bacteria, viruses, spores, fungi, prions, organic matter, minerals, proteins or associated structures. The BOD, TDS and TSS can be lowered or eliminated as desired. This action is directly proportional to the quantity of EMODs in the AOS applied to the liquid target material.

A method of chemical extraction and power generator cooling includes receiving an aqueous solution with dissolved inorganic carbon. The method further includes extracting the dissolved inorganic carbon from the aqueous solution and collecting the dissolved inorganic carbon. The aqueous solution is then acidified and supplied to the power generator to cool the power generator.

The present disclosure is drawn to evaporation panel assemblies, systems, and methods. For example, a modular evaporation panel system can include a plurality of evaporation panels with individual evaporation panels including evaporation shelves that are laterally elongated, vertically stacked, and spaced apart; vertical support columns positioned along the evaporation shelves to vertically support and separate the evaporation shelves; female-receiving openings defined by multiple evaporation shelves and multiple support columns; and male connectors positioned at lateral ends of the evaporation panels. The male connectors can be releasably receivable by the female-receiving openings of an adjacent evaporation panel, thereby providing modular assembly and disassembly of multiple evaporation panels relative to one another.

A method of increasing operational efficiency of a power plant includes determining an average rate of accumulation of scale-forming compounds in a cooling water source, directing water from the cooling water source having a first concentration of scale forming compounds through a treatment system to produce a treated water having a lower concentration of scale-forming components than the first concentration by operating the treatment system with operating parameters selected such that a rate of removal of the scale-forming components from the water in the treatment system is greater than the average rate of accumulation of the scale-forming components, directing the treated water back into the cooling water source, and circulating water including the treated water from the cooling water source through a cooling system of the power plant.

Embodiments provide methods and strictures for purification or volume reduction of a brine by an advanced vacuum distillation process (AVMD) to achieve higher flux by passage of vapors through an AVMD distillation unit. In one example, brine is circulated in a tank. The tank may include one or more membrane pouches that are submerged in the circulating brine or placed above the water level of the hot circulating brine. In other embodiments the membrane pouches are outside of the tank that includes the hot circulating brine but still in communication with it. The circulating brine is heated, allowing creation of water vapor. Using a vacuum, the water vapor is drawn through the membrane, where it may be condensed and subjected to further beneficial use. This process can concentrate to levels to generate crystals or solids, which can be separated and utilized.
