Abstract: Provided is a purification material capable of highly efficiently removing contaminant components from water. A water purification material has a composition represented by a mixing ratio of zeolite, ferric hydroxide, activated carbon, titanium oxide, and magnesium hydroxide of 6 to 7:1 to 2:0.5 to 1:0.01 to 0.05:0.01 to 0.10 in terms of weight ratio.

Abstract: Provided is a purifying material capable of highly efficiently removing contaminant components from wastewater. A water purifying material having a composition of 30 to 40% total iron, 1 to 5% titanium, 0.1 to 1% magnesium, and 0.1 to 0.8% silica (silicon), and a method for manufacturing the water purifying material including: adding caustic soda to a solution containing 200 to 100 mg/L of bivalent iron, 20 to 100 mg/L of titanium ions, 5 to 50 mg/L of magnesium, and 3 to 30 mg/L of silica under conditions of 30 to 50° C. and pH 6.8 to 7.2 to carry out neutralization and reaction; separating and collecting an obtained solid at 100° C. or less; and drying the collected solid.

Abstract: A liquid oxidizing system has a closed circuit in which a liquid containing matter to be oxidized is circulated. The circuit is provided with an ejector for forming a jet stream of the liquid into which oxygen, or both oxygen and an oxidizing catalyst are supplied. The oxygen (and the catalyst) rapidly contacts the matter to be oxidized in the jet stream and oxidizes it. The system is not only applicable to the treatment of waste water, such as from factories, but also useful for making a product by oxidizing a liquid, e.g. iron polysulfate which is a good coagulant.
