The Hydrogen Cycle uses the reverse osmosis process (RO) to purify water before its use in the electrolyzers to produce the hydrogen. The RO process uses five stages of filtering to remove all the suspended solids in the water.
The first three stages in the RO process removes 95% of the suspended solids in the water. At this stage the water is suitable for human consumption. This portion of the RO process can be scaled up independent to provide potable water to meet community needs. The final operation in creating the potable water is to bathe the processed water and UV (ultraviolet) light to kill any bacteria that might still be in the water.
The final two stages of the RO filtering process complete the removal of all suspended solids in the water, which is now DI water (distilled water). This portion of the process is size to meet the demands of the electrolyzer and hydrogen production.
