A water purification process for removing dissolved solids of the type that are normally present in a municipal water supply or the like. The process uses a forced draft decarbonator (30) having an inlet (32) and a product outlet (34), a vacuum degasifier (36) having an inlet (38), a product outlet (40) and a water level sensor (42), and a reverse osmosis unit having an inlet, a product outlet and a brine outlet. Preferably, the vacuum degasifier is located downstream of the forced draft decarbonator (30) with the product outlet (34) of the forced draft decarbonator (30) being coupled to the inlet (38) of the vacuum degasifier (36). The reverse osmosis unit is located downstream of the vacuum degasifier (36) with the product outlet (40) of the vacuum degasifier (36) being coupled to the inlet of the reverse osmosis unit. Water to be purified is provided to the inlet (32) of the forced draft decarbonator (30) at a predetermined rate. According to the invention, the rate at which water to be purified is provided to the inlet (32) of the forced draft decarbonator (30) is a function of a predetermined water level in the vacuum degasifier (36). |
