摘要： The present disclosure includes a process and method for brine concentration. A Nano filtration (NF) membrane removes divalent ions while permeating monovalent ions. In a sequential concentration process (membrane and thermal), the monovalent ions reach crystallization. The brine concentrator system can treat the brine of the desalination plants or the effluent of the industrial and chemical plants. The disclosed system can treat the produced water of the oil and gas sector. Two options are disclosed herein. In the first option, an RO system is used to recover water from an FO concentrator where in the second option the advanced MED-AB technology is used to recover water from the FO brine concentrator. The merit of the second option is explored where waste heat energy is available.

摘要： A method of separating contaminants from at least one continuous fluid stream. The method includes steps that are performed inside of a solids dissociation apparatus (SDA) and inside of a solids separation apparatus (SSA) for separating contaminants from at least one continuous fluid stream. The method includes steps of eviscerating the contaminants in the at least one continuous fluid stream inside of SDA upon pumping the at least one continuous fluid stream in SDA, generating a traveling sonic wave in SDA, and cavitating the at least one continuous fluid stream in SDA. The method also includes steps of removing the eviscerated contaminants of a first configuration from the at least one continuous fluid stream by SSA upon generating a standing sonic wave in SSA and forcing the eviscerated contaminants into at least one set of ports of at least one removal stage of a tower of SSA.

摘要： The invention relates to a method and a system for purification of water in a water purification system. The water purification system comprises first and second mixing reactors, first and second flotation reactors and first and second filters all serially and fluidly connected in a flow direction of the water as well as an electrolyzer. During the process, electrochemical synthesis of the reagents takes place in the cathode and anode chambers of the electrolyzer, respectively. Moreover, the electrochemically synthesized catholyte and anolyte are dosed into the water kept in the first and second mixing reactors, respectively. Then the mixtures in the first and second mixing reactors are mixed. After that, the flow of the treated water leaving the mixing reactors is passed through the first and second flotation reactors and afterwards through the first and second filters downstream of the first and second mixing reactors.

摘要： A particle measuring apparatus is provided that has improved measurement accuracy regardless of particle diameters and that ensures prompt measurement. A particle measuring apparatus has: first and second particle counters that obtain a number of particles that are contained in water that flows in a predetermined section of an ultrapure water production apparatus; and particle number calculation means that calculates the number of the particles that are contained in the water that flows in the predetermined section for each particle diameter range based on measurement results of the first and second particle counters. The first particle counter and the second particle counter have different counting efficiencies.
