摘要： A reverse osmosis system and method for operating the same includes a fluid reservoir, a valve and a brine feed tank in fluid communication with the fluid reservoir through an input. The brine feed tank has brine feed fluid therein. The system also includes a high pressure pump and a pressure vessel in fluid communication with the fluid reservoir through the high pressure pump. The pressure vessel comprises a permeate outlet. The brine feed tank is in fluid communication with the pressure vessel. During a permeate production cycle, the high pressure pump pumps additional fluid under high pressure from the fluid reservoir into the pressure vessel using a high pressure pump. The pressure vessel communicates brine fluid into the brine feed tank. The high pressure pump raises a pressure in the pressure vessel until an amount of permeate is produced from a permeate output of the pressure vessel.

摘要： An apparatus includes a filtration skid configured to generate a filtrate through at least one of microfiltration and ultrafiltration. The apparatus further includes a desalination skid fluidly connected to the filtration skid. The desalination skid is configured to perform reverse osmosis desalination on the filtrate to generate a permeate, where the filtrate travels from the filtration skid to the desalination skid without traversing a storage tank. In one embodiment, the apparatus further comprises a controller, where the filtration skid and the desalination skid are integrated to provide self-adaptive operation of the filtration skid and the desalination skid in response to control by at least one of a supervisory controller and a local controller. In one embodiment, the control responds to at least one of temporal variability of feed water quality, a permeate production capacity target, and a permeate quality target.

摘要： A reverse osmosis (R.O.) water purifier system that collects and stores pure water at low pressure and dispenses it at high pressure. Impurities left behind when the water passes through a R.O. module are disposed of by two methods: the fast flush method and the slow flush method. In the fast flush method, water entering a R.O. module may take two paths to escape therefrom. The first path constrains it to travel through a semi-permeable membrane in the module which filters out undissolved solids and which restrains the passage of dissolved liquids. The second path allows it to travel through the R.O. module, without passing through the membrane, thereby carrying out those impurities left behind by the water passing through the membrane. The purified water is directed to one side of a compartmented storage tank and the waste water from the module is directed to a control valve. From the control valve, the waste water may be directed through a restriction to a drain or it may be directed to the other compartment of the storage tank where the purified water is held. In the slow flush method, water enters a control valve, travels to the R.O. module, and has two paths of escape therefrom. The first path contrains it to go through the semi-permeable membrane in the R.O. module, and through a check valve to storage or outlet. The second path allows the water to escape through the R.O. module, thereby carrying to a drain the impurities left behind.
