Abstract:
A system and method for removing minerals from a water source and concentrating these minerals for ease of reuse or disposal includes passing the water from a suitable source through cascaded membrane filters, the reject outputs of each of which are connected to the inputs of the next membrane filter in the cascade. At the input of each of the membrane filters, a pre-filter in the form of a micro-filtration filter, an ultra filtration filter, or a slow sand filter, is used to remove sediment and impurities from the water stream prior to the application of the water to the input of the next membrane filter in the cascade.
