摘要： Methods and systems for treating a waste stream (202) in a waste treatment system (204) involve performing a unit process (206) by contacting the waste stream (202) with oxyhydrogen-rich gas (214) generated on-site by an oxyhydrogen gas generator (207). The gas generator (207) preferably involves applying a pulsed electrical signal to a series of closely-spaced electrodes that are submerged in the waste stream (202) to dissociate a water component of the waste stream (202), thereby producing oxyhydrogen-rich gas (214, 220). Operation of the gas generator (207) in the waste stream (202) may accomplish one or more unit processes (206) for waste treatment, such as conditioning, stabilization, thickening, and dewatering, among others. At least a portion of the oxyhydrogen-rich gas (220) can be conveyed for a second use (222) in the waste treatment system, such as a source of combustible fuel for incineration or power generation, for example.

摘要： Disclosed is a method for cleaning aeration elements (1) provided with pores or bores in aerated basins (2) of wastewater treatment plants or water treatment plants. The aeration field (4) formed by the aeration elements (1) and the pipes (3) connecting said aeration elements to each other is completely filled with a cleaning agent in a fluid form by applying pressure that is high enough to send said cleaning agent through the pores or bores of the aeration elements (1). After applying the cleaning fluid on the pores or bores of the aeration elements (1) for a variable amount of time, the aeration field (4) is emptied again. In a further optional cleaning step, the aeration field (4) is cleaned once again with a rinsing fluid, preferably water. Also disclosed are the use of an alkaline cleaning agent with a pH value of at least 10, preferably 12, and advantageous compositions of the cleaning fluid used for cleaning aeration elements.

摘要： This invention is directed to methods for quickly inverting and dispersing a flocculant in an aqueous slurry to achieve settlement of solids and clarification of the slurry water. In particular, this invention relates to methods for quickly inverting a flocculant-containing emulsion in-line without significantly destabilizing the emulsion. The methods comprise dosing water with at least one water-in-oil emulsion containing at least one of a flocculant polymer and hydrophilic surfactant and subjecting the water and emulsion to a high shear, turbulent reverse flow, such that the combination of the surfactant and shear synergistically inverts the emulsion, so the flocculant may be directly injected into the slurry. In an alternative embodiment, the emulsion is fed directly to the slurry to be treated and subjected to high shear, such that the emulsion inverts in situ, releasing the flocculant into the slurry for solids/liquid separation.

摘要： Selon un procédé de production de particules agglomérées en polymères finement pulvérisés solubles ou gonflables dans l'eau, on déshydrate azéotropiquement des émulsions d'eau dans l'huile de polymères solubles ou gonflables dans l'eau en présence de 1 à 40% en poids, par rapport aux polymères, de glycols de polyalkylène, obtenus par fixation par addition d'oxydes d'alkylène ayant 2 à 4 atomes de carbone sur des alcools, des phénols, des amines ou des acides carboxyliques et contenant au moins deux unités d'oxyde d'alkylène polymérisées, puis on isole les particules agglomérées polymères. L'invention concerne également ces particules agglomérées en polymères finement pulvérisés solubles ou gonflables dans l'eau. Les particules agglomérées polymères solubles dans l'eau sont utilisées comme floculants, comme agents de rétention et comme déshydratants, alors que la poudre polymère gonflable dans l'eau est utilisée comme épaississant dans des systèmes aqueux, notamment comme épaississant de pâtes d'impression textile.

摘要： Abstract A method and device for dosing at least one water-soluble chemical (8) of a solid or semisolid form, for example in gel form, into injection water for use in an underground reservoir. Water is circulated in at least one circulation circuit (4), in which the water comes into contact with said at least one water-soluble chemical (8) of a solid or semisolid form. The water is circulated in the at least one circulation circuit (4) until the water has reached a desired concentration of the at least one chemical (8). The chemical-containing water is then dosed into the injection water.
