Initial liquid containing fine bubbles is produced by mixing water and air (step S11). Fine bubbles have diameters of less than 1 m. The density of bubbles in the initial liquid is measured (step S13), and when the measured density is less than a target density (step S14), the initial liquid is heated and reduced in pressure so that the liquid is vaporized (step S15). As a volume of the liquid decreases, the density of fine bubbles increases, and high-density fine bubble-containing liquid is easily obtained. Alternatively, by increasing the density of fine bubbles in the initial liquid with using a filter that does not pass all fine bubbles, high-density fine bubble-containing liquid is easily acquired (step S15). When the density of bubbles in the initial liquid is greater than the target density, the initial liquid is diluted (step S16).

Powder blends are described comprising blends of particulate water soluble high molecular weight polymer flocculants. The polymer flocculants can include polyethylene oxide, polyDadmac, Dadmac-acrylamide copolymers, copolymers thereof and combinations thereof. The powder blends allows the use of fine powders while reducing potential air quality and safety issues. The powder blends can be used for waste water purification, fiber dewatering, and the like. The powder blends can be diluted by a water dilution flow prior to entering a waste water stream.

The present disclosure provides a system and a method for producing deuterium depleted water. The system includes a chlor-alkali electrolysis cell, a compressor, a cooling water scrubber tower, a hydrogen combustor, a boiler, a cooling condensation apparatus, a crude deuterium depleted water storage tank, a water purification apparatus and a water filling machinery. The method includes: generating hydrogen from a chlor-alkali electrolysis of salt water in the chlor-alkali electrolysis cell; increasing the pressure of the generated hydrogen; purifying and cryogenically cooling the generated hydrogen; combusting the mixture of hydrogen and oxygen to generate water steam; condensing the water steam to produce the crude deuterium depleted water in the cooling condensation apparatus; storing the produced crude deuterium depleted water in the crude deuterium depleted water storage tank; purifying the produced crude deuterium depleted water through the water purification apparatus; packaging the purified deuterium depleted water with the water filling machinery.

This invention relates to a method and an apparatus for energizing and aerating fluids, comprising the step of subjecting a starting liquid to a process in order to produce an energized liquid the molecules of which are clustered and can have a specific wavelength, magnetic field, and hydrating properties.

Water charging machine wherein the water being treated is moved through a geometric series of spheres, creating a series of waterfall-like events within this invention. Oxygen may be introduced into the stream of water either upstream of this invention, or into the inside of this invention, or both, to provide a long shelf life incorporation of the gaseous oxygen into the water through vortex and waterfall actions. The water and oxygen is also exposed to a negative or positive magnetic field and a piezoelectric field as it travels through this invention, to provide a substantial Zeta potential.

Methods and systems for recovering nutrient-enriched products from wastewater are provided. Liquid permeate streams recovered from a membrane-type bioreactor may be further treated to remove carbonate species, and then contacted with at least one calcium-containing coagulant. The resulting solids-containing product may be enriched in one or more nutrients, such as phosphorous, and can be used in subsequent applications. such as fertilizers. The resulting liquid stream may also be treated to provide a treated water stream. Methods and systems described herein provide energy-efficient, sustainable processes for treating wastewater and recovering valuable products therefrom.
