Abstract: A filter system comprises a hollow fiber membrane filter having pores; and an electrostatic adsorption filter partially or wholly having positive charges to be ion adsorbed with nanoparticles of negative charges by an electrostatic attraction, the nanoparticles which exist in the water, and the electrostatic adsorption filter configured to remove in advance the nanoparticles from the water to be supplied to the hollow fiber membrane filter, to prevent a water passing amount of the hollow fiber membrane filter from being rapidly reduced. According to the present invention, the viruses existing in raw water may be removed in accordance with a size exclusion mechanism of the hollow fiber membrane filter, and the nanoparticles, which cause the reduction of the water passing amount of the hollow fiber membrane filter, may be removed using the electrostatic adsorption filter.

Abstract: The present invention relates to a process for the preparation of Calcium Silicate Hydrate anion exchange membrane (cement paste) with an ionic conductivity of the order of 10−3 S/cm. The membrane can be formulated by mixing Ordinary Portland Cement (OPC) and water with the cement to water ratio of 1:0.45. After initial setting time, the membrane undergoes curing in 7% calcium chloride solution and the Cl− ions in the membrane is converted to OH− form by immersing into saturated Ca(OH)2 solution with pH 14 and it has been washed to remove the excess alkali. This membrane has high mechanical strength (Ultimate Tensile Strength: 6.3 MPa) and does not deteriorate even at high temperature (up to 450° C.) and alkaline atmosphere (pH 11.5-14). Also disclosed is a method of producing in-situ formation of membrane electrode assembly. This invention encompasses a process for producing and using the membrane in water electrolysis and fuel cell.

Abstract: The invention relates to purifying unwanted moderately saline water. The methods of the present invention including passing moderately saline water through an ion exchange media saturated with ammonium salts to produce fertilizer water. In addition, the present invention relates to a method of passing moderately saline water through a dual bed cation and anion exchange process for producing purified water. The first cation exchange media is saturated with acids of hydrochloric, nitric or sulfuric acids. Meanwhile, the second ion exchange media is saturated with ammonium hydroxide. Passing the moderately saline water through the first ion exchange media creates an acid rich water which is then passed through the second ion exchange media to remove chloride, sulfate, nitrate, and nitrite anions. Through a regenerative cycle, a fertilizer water is produced which is rich in ammonium chloride, ammonium nitrate or ammonium sulfate.

Abstract: Chlorous acid is generated from a chlorite salt precursor, a chlorate salt precursor, or a combination of both by ion exchange. The ion exchange material facilitates the generation of chlorous acid by simultaneously removing unwanted cations from solution and adding hydrogen ion to solution. Chlorine dioxide is generated in a controlled manner from chlorous acid by catalysis. Chlorine dioxide can be generated either subsequent to the generation of chlorous acid or simultaneously with the generation of chlorous acid. For catalysis of chlorous acid to chlorine dioxide, the chlorous acid may be generated by ion exchange or in a conventional manner. Ion exchange materials are also used to purify the chlorous acid and chlorine dioxide solutions, without causing degradation of said solutions, to exchange undesirable ions in the chlorous acid and chlorine dioxide solutions with desirable ions, such as stabilizing ions, and to adjust the pH of chlorous acid and chlorine dioxide solutions.
