A system and method for continuously treating blowdown water derived from one or more boilers using a microwave reactor, a cooling system, and an ion exchange filter to remove insoluble solids, organic matter, bacteria, and other impurities. The recovered water is stored, treated with a corrosion inhibitor, an oxidizing biocide, a non-oxidizing biocide, and a scale inhibitor, before being recycled for reuse in the boiler system.

A water quality management device is provided with a water quality index value acquisition unit which acquires water quality index values including a makeup water quality index value indicating water quality of makeup water and a circulating water quality index value indicating water quality of circulating water, and a determining unit which determines an amount of concentration control associated with a concentration rate of a circulating water system based on the water quality index values acquired by the water quality index value acquisition unit.

A method for generating process steam using condensate recycled in the form of feed water is described and illustrated. In order to be able to achieve a higher efficiency with the method, it is proposed that the process steam is delivered to a consumer device (V) to form a condensate by at least partial condensation of the process steam, that the condensate from the consumer device (V) is fed to a feed water treatment for treatment, that feed water from the feed water treatment is separated into a steam phase and a liquid phase in a flash tank, that the liquid phase of the feed water is evaporated in an evaporator to form a raw steam, and that the steam phase of the feed water and the raw steam are compressed in at least one compressor to form process steam.

A method for operating a steam power plant having a water-steam circuit, according to which method the process wastewater produced is collected from the water-steam circuit, in a separated manner according to the degree of contamination thereof, in a number of partial wastewater quantities is provided. At least a first partial wastewater quantity having a first degree of contamination and at least a second partial wastewater quantity having a second degree of contamination are formed in the process. The second degree of contamination is higher than the first degree of contamination. The first partial wastewater quantity and the second partial wastewater quantity are mixed together in such a manner that a combined process wastewater is produced, which is fed to a wastewater treatment plant.

A method for processing a liquid medium, wherein the medium to be processed is conducted through a liquid circuit and the medium to be processed is heated up in the liquid circuit with the aid of a heat exchanger. A liquid-vapor separation process is carried out in a separating device, and a liquid obtained in the liquid-vapor separation process is conducted into the heat exchanger as a heating medium.

A system for producing steam includes a source of superheated water with superheated water output; a membrane filtration system in fluid communication with the superheated water output and including a membrane filter with a permeate side and an opposing retentate side. The membrane filter includes a separation membrane constructed to reject organic molecules. The system may be used for removing organic compounds, such as anti-corrosion agents or contaminants, from superheated water to produce steam. A method for producing steam includes directing a cross-flow of heated pressurized water including a first concentration of an organic compound across a membrane filter. The membrane filter includes a separation membrane constructed to reject the organic compound; and one or more support layers adjacent the separation membrane. A steam permeate including a second concentration of the organic compound is collected, where the second concentration is lower than the first.
