Abstract
A combination of an air lift pump and a mechanical pump is used to lift a fluid from a lower level to a higher level. In preferred embodiments compressed air is released below the level of a submerged mechanical pump having an impeller, such that the compressed air impinges upon the low pressure side of the impeller. The combination may be used advantageously in conjunction with a semipermeable membrane disposed within a deep channel to lift a purified fluid.
