Abstract: A method and apparatus for desalinating saltwater using concentration difference energy is disclosed. In order to desalinate saltwater that is contained within a product chamber, a drive cell is used to generate a drive voltage. The product chamber has a desalination voltage such that when a sufficient voltage is applied to the product chamber, anions and cations migrate out of the product chamber, thereby desalinating the water. The sufficient voltage, which includes the drive voltage and which is equal to or greater than the desalination voltage, is applied to the product chamber, consequently effecting desalination. Beneficially, concentration difference energy can be generated using a concentrated solution, which can be generated using, for example, solar energy.

Abstract: Improvements in product water throughput from a reverse osmosis (RO) membrane achieved by thinner feed spacers in the RO element (22), enhanced recovery (ratio of permeate to feed), pressure recovery of the retentate fluid pressure opposing the feed water pressure, and fluid pulsing of the RO element feed stream. These features are preferably combined to optimize the performance and cost per unit volume of water produced. The system of the invention preferably comprises a dual head reciprocating pump (20), an RO element (22) with a housing, and a differential pressure activated (“DPA”) valve (24). The DPA valve (24), in combination with offsetting fluid pressures on the two pump heads (28, 30), generate energy recovery. The frequency and amplitude of the reciprocating pump (20) create a pulse wave in the RO element (22) that improves permeate quality and throughput. A control system preferably monitors system parameters to optimize the reciprocating pump (20) speed and amplitude to tune the optimal frequency and amplitude required for maximum throughput and permeate quality from any given RO element (22) configuration.

Abstract: Provided are an apparatus and a method for purification of water in which impurities in contaminated water can be removed with a reduced amount of flocculant and with high efficiency. The apparatus comprises, in the order from the side where contaminated water is introduced, an electrolysis tank (1) for electrolyzing the contaminated water, a gas mixing tank (2) for mixing carbon dioxide into the contaminated water electrolyzed, a coagulation tank (3) for mixing Fe3+ supplied from a flocculant producing device (7) to coagulate impurities in the contaminated water, and a floatation tank (4) for floating and separating the impurities coagulated. The electrolysis tank (1) electrolyzes the contaminated water to lower zeta potential of colloid particles in the contaminated water, and then the contaminated water is mixed with Fe3+ in the coagulation tank (3), thereby reducing the amount of positively charged Fe3+ to be added for neutralizing the colloid particles.

Abstract: A floatable sanitizer employs a plurality of electrodes to contact a body of water in order to achieve a near maintenance-free sanitizing chemical generator. In one embodiment, the sanitizing chemical is chlorine and the chlorine is generated by an electrolytic process. The electrolytic reaction may be powered by photovoltaic cells, making the apparatus self-contained and able to float freely within a body of water. In one embodiment, the energy source is channeled through a polarity-reversing module. The polarity-reversing module alternates the direction of the current generated by the photovoltaic cells at a predetermined time interval. The reversing of the polarity reduces scale build-up and prevents corrosion of the metal electrodes.

Abstract: Deionizers using the electrode configurations of electrochemical capacitors are described, wherein the deionizing process is called capacitive deionization (CDI). During deionization, a DC electric field is applied to the cells and ions are adsorbed on the electrodes with a potential being developed across the electrodes. As electrosorption reaches a maximum or the cell voltage is built up to the applied voltage, the CDI electrodes are regenerated quickly and quantitatively by energy discharge to storage devices such as supercapacitors. In conjunction with a carousel or Ferris wheel design, the CDI electrodes can simultaneously and continuously undergo deionization and regeneration. By the responsive regeneration, the CDI electrodes can perform direct purification on solutions with salt content higher than seawater. More importantly, electrodes are restored, energy is recovered and contaminants are retained at regeneration, while regeneration requires no chemicals and produces no pollution.
