Powder blends are described comprising blends of particulate water soluble high molecular weight polymer flocculants. The polymer flocculants can include polyethylene oxide, polyacrylamide, 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.

Initial liquid containing fine bubbles is produced by mixing water and air (step S11). Fine bubbles have diameters of less than 1 μm. 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).

Ultrafine bubbles with a diameter of less than 1.0 μm are generated in liquid by causing film boiling in liquid by means of a heater.

An electrodeionization device (EDI device) with improved performance for removing weak acid components such as boron includes a deionization chamber partitioned by a pair of ion exchange membranes between an anode and a cathode. A grain size of 0.1 mm or more and 0.4 mm or less is defined as small grain size, and a grain size of more than 0.4 mm is defined as large grain size. In the deionization chamber, a large grain size layer made of an ion exchange resin of large grain size and a mixed grain size layer in which an ion exchange resin of large grain size and an ion exchange resin of small grain size are mixed are arranged along a flow of water to be treated.

A process for treating water includes the steps of passing the water through a conduit having spaced apart cavitation zones and a central laminar flow zone to increase negative hydrogen ions in the water, to increase electron activity, and to decrease molecular clustering, and thereby reduce surface tension of the water for improved hydration by a body consuming the water, including people, animals, and plants.

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.
