The Gift of Water purification process is quite simple and similar to most public systems used in the United States today. The system incorporates both a physical filtration step for particle removal and a chlorination step for disinfection. This dual approach leads to high-quality treated water.
The Gift of Water system follows a two-bucket approach. The process involves prechlorination to disinfect the raw water from bacteria, followed by a 1 micron (μm) polypropylene string filter to remove suspended solids and larger disease-causing protozoa in the first bucket. The second bucket involves granular activated carbon (GAC) to remove organics and residual disinfectants, and then post-chlorination to keep the product water safe from recontamination. Users access the treated water via a tap in the bottom bucket.
