摘要： An apparatus for removal of organic materials from water includes a reactor (40) for photocatalytic oxidation and/or ionization of organics in the water stream and an ion exchange column (82) for removal of CO, dissolved acids, and ionized organics formed in the reactor from the water stream. The reactor includes an elongated flow chamber having an inlet (57) at one end and an outlet (54) at the opposite end. A photocatalytic material is provided as a surface layer on a number of solid members in the chamber, typically a number of rods (58) extending generally parallel to the axis of the flow chamber. The catalyst may be TiO formed by oxidizing the surface of Ti rods. An elongated UV lamp (64) fitting within a tubular quartz window extends along the axis of the reaction chamber. An external circuit connects the electrodes and the water, such that a current flows in the water in the reaction chamber. A potential of up to 600 VDC may be applied between the solid electrodes and water in the chamber.

摘要： Methods and compositions are disclosed for treating swimming pool waters in order to remove one or more nutrients necessary for algal growth and to accelerate the breakdown of objectionable chloramines within chlorinated pool waters. The target nutrients of preference are those containing phosphorus or nitrogen. Phosphorus nutrients are preferably removed by ion-exchange with finely divided lanthanum carbonate, or by direct precipitation in the pool with liquid lanthanum chloride. Nitrogen nutrients (including, in particular, chloramines) may be removed (possibly with the aid of catalysts and in separate reactors). The same reagents used to scavenge phosphates are useful in this regard, the nitrogen being released from the pool water as a nitrogenous gas. To allow the fine lanthanum carbonates to be conveniently handled in the pool environment, they may be linked to larger carrier particles, such as those of diatomaceous earth, or they may be embedded within porous beads formed from polymers or gels. In this form the reagent can be either added to, retained within and backwashed from pool filters, or added directly to pools (with or without a flocculating agent) and sucked to waste after settling. A variety of formulations for these purposes is disclosed.

摘要： A first reaction/adjustment tank (1) has a lower portion (1a) containing a calcium carbonate mineral (9A), an upper portion (1b) containing a calcium carbonate mineral (9A) and a plastic filler (13A), and an air lift pump (16A) for circulating waste water from the lower portion (1a) to the upper portion (1b). Exhaust gas is introduced into a space (S1). A second reaction/adjustment tank (2) has a lower portion (2a) containing a calcium carbonate mineral (9B) and charcoal (23), and an upper portion (2b) containing charcoal (23) and a plastic filler (13B). Waste water circulates sequentially through the lower and upper portions (1a, 1b) of the first reaction/adjustment tank (1), and the lower and upper portions (2a, 2b) of the second reaction/adjustment tank (2). Exhaust gas circulates sequentially through the upper portion (1b) of the first reaction/adjustment tank (1) and the upper portion (2b) of the second reaction/adjustment tank (2).

摘要： Anorganische Metallverbindungen, insbesondere Salze, Oxyde oder Hydroxyde, werden aus cyanidhaltigen Elektrolyten und anderen Lösungen entfernt, indem der Lösung mindestens ein Teil ihrer Flüssigkeit entnommen und die entnommene Flüssigkeit in einem Kühlbehälter unter Rühren im Gebiet des metastabilen Bereiches bis zum möglichen Auskristallisieren der Salze bzw. Hydroxyde abgekühlt wird. Der so abgekühlten Lösung wird zur Einleitung der Kristallisation stossweise Energie zugeführt. Die auskristallisierten Metallverbindungen werden von der Flüssigkeit abgetrennt und die abgetrennte Flüssigkeit wird in die Lösung zurückgeleitet. Geeignete Energieträger für die stossweise Energiezufuhr sind insbesondere: Ultraschall, Gleichstrom, Wechselstrom, Mikrowellen, Magnetismus, Laserstrahlen, Infrarotstrahlen; und Ultraviolettstrahlen. Zweckmässig erfolgt dabei die Abkühlung bis zum Auftreten der durch das Freiwerden der Kristallisationswärme bedingten exothermen Reaktion; anschliessend wird die Temperatur vor dem Abtrennen der Metallverbindungen noch 2 bis 4 Minuten bei 0,5 bis 1 °C unterhalb dieser Temperatur gehalten. Die Kühlgeschwindigkeit beträgt vorzugsweise -0,5 °C/Minute, bei geringer Rührerdrehzahl.

摘要： A process for the removal and recovery of ammonia from liquid waste, characterized essentially by the following operations:

reacting the liquid waste with pure carbon dioxide, or with a gaseous mixture rich in carbon dioxide, or with at least one carbonate, to give ammonium carbonate;
reacting the resulting ammonium carbonate with calcium chloride to give calcium carbonate and ammonium chloride;
causing the resulting calcium carbonate to undergo thermal decomposition to give calcium oxide and carbon dioxide;
using, optionally, the carbon dioxide formed after thermal decomposition of calcium carbonate for said reaction with the liquid waste; and
using the calcium oxide, formed after thermal decomposition of calcium carbonate, for the production of pure ammonia, by reaction with the ammonium chloride obtained in said reaction between ammonium carbonate and calcium chloride.

The figure shows a flow sheet of a plant allowing the operations of an embodiment of the above process.

摘要： A system for treating groundwater contaminated with acidity or other contaminants is disclosed. The system involves excavating a trench into the aquifer in the path of the contaminant plume, and placing a body of active material in the trench. The active material depends on the particular contaminant: organic carbon may be used when the contaminant is ferrous sulphate, or hexavalent uranium oxide, or dissolved nitrate; pyrite or elemental iron may be used when the contaminant is eg chromium oxide. The active material causes the contaminant to transform or break down by chemical reaction into harmless precipitates and substances.
