    摘要： The present invention relates to an air diffusion device comprising a tubular main pipe for receiving a supply of air from an air supply device, and a branch pipe connected to the main pipe, wherein the branch pipe is connected at one end to the main pipe and open at the other end, one or more air diffusion holes are formed in the branch pipe, at least some of the air diffusion holes are formed so as to be at the top in the vertical direction when the main pipe is laid horizontally, and the branch pipe is configured so that the opening at the other end faces downward in the vertical direction. According to the present invention, it is possible to provide an air diffusion device in which water to be treated is caused to flow into an air diffusion pipe, thereby allowing closing of the air diffusion holes to be suppressed and sediment to be easily removed in the branch pipe as well as an air diffusion method and water treatment device in which this air diffusion device is used.

    摘要： Systems and methods for monitoring biofilm growth are provided. A method comprises supporting at least one coupon in a water reservoir, wherein the water reservoir feeds water into a tower interior, removing the at least one coupon from the water reservoir, and measuring a level of biofilm growth on the at least one coupon. The level of biofilm growth on the at least one coupon is predictive of a level of biofilm growth within the tower interior. Providing an indicator of predictive biofilm growth may allow measures to be taken to prevent biofilm growth in other sectors or areas of the tower.

    摘要： A method of producing stable disinfectant for use as a biocidal composition. The method comprises: A) providing reagents, B) asynchronously feeding the at least two of the reagents into a wide space, and C) allowing all the reagents to come into contact and mix with each other. The reagents comprise: a) an amine source of disinfectant in concentrated form, b) an oxidizing halogen compound in concentrated form, and c) a diluent. The use of asynchronous feeding and a wide space results in a dynamic biocide regimen. This regimen results in a changing environment that infestations have difficulty adapting to. This method also imparts superior results due to the avoidance of channeling effects which would otherwise weaken the effects of the biocide.

    摘要： A process for desalinating water is disclosed. The process comprises the steps of passing a feed stream of saline solution 2′ in a first desalination step through a reverse osmosis membrane desalination plant 3′ comprising at least one reverse osmosis desalination unit 4′ to form a first product water stream 5′ having a reduced salt concentration relative to that of the feed stream of saline solution 2′ and a first byproduct stream 6′ having an increased salt concentration relative to that of the feed stream of saline solution 2′ characterized in that the first byproduct stream 6′ is passed in a second desalination step through a falling film crystallization unit 7 to form a second product water stream 8 having a reduced salt concentration relative to that of the first byproduct stream 6′ and a second byproduct stream 9 having an increased salt concentration relative to that of the first byproduct stream 6′. The invention further relates to an apparatus 1 for carrying out said process. The present invention further relates also to the use of the process or apparatus 1 for the reduction of the volume of the first byproduct stream 6′ of a reverse osmosis membrane desalination plant 3′, preferably an in-land desalination plant 3′, or in a device or plant or process for producing desalinated water, for salt production, for co-production of power and desalinated water, or for air conditioning.
