A method for treating congestive heart failure (CHF) has been developed that restores kidney renal functions by artificial vasodilation of at least one kidney. A vasodilator drug is locally delivered to the kidney via a kidney perfusion catheter. The drug can be mixed with the patient's blood, saline or other suitable solvent and the mixture directly applied to the kidney through the catheter. The restoration of kidney function assists the heart by removing excess fluid, urine and toxin from the patient, and by normalizing the patient's renin-angiotensin system and other neurohormonal substances. The method is applicable to treat chronic and acute CHF.

The method for purifying liquids purifies a saline liquid, e.g., salt water, using a plurality of first phase reverse osmosis (RO) units and at least one final phase reverse osmosis unit. The plurality of first phase reverse osmosis units are arranged in series. At least some of the concentrate in a last reverse osmosis unit of the series is recycled back to the permeate or output side of that unit to provide a mixed permeate.
